How To Choose A Stepless Ear Clamp Using A Pinch Clamp Size Chart

The correct clamp selection begins by measuring the assembled hose carefully and comparing the result with a Pinch Clamp Size Chart. When the correct Stepless Ear Clamp is chosen, the connection is less likely to leak, crush the hose, or fail early. Here are straightforward steps to help you make the right choice and ensure a perfect fit.

To measure hose O.D., take the measurement after the fitting is fully inserted. Record the assembled outside diameter in inches or millimeters. For best results, choose a clamp range that places the measured hose O.D. near the middle of the listed range.

Oetiker 167 Series Stepless® Ear Clamps are a useful example for understanding range selection. If the Oetiker Inc. spec ranges from 1.547″–1.673″ (39.3mm–42.5mm), select a clamp that positions your measured O.D. near the midpoint. That sizing approach helps avoid clamps that are too loose or too aggressively compressed.

Interpreting a Pinch Clamp Size Chart involves examining minimum and maximum closure diameters and aligning series details with your application. Ear width, band width, and band thickness also matter because they affect clamping force, fit, and pressure distribution.

The chart should be used to compare the clamp’s ear width, band width, and band thickness before ordering. For instance, the 167 Series Stepless® Ear Clamps have ear width of 10.0mm, band width of 7mm, and band thickness of 0.6mm. Ensure the ear will reduce by at least 40% upon crimping for sufficient clamping force.

Clamp material and published specifications directly affect service life, compatibility, and compliance. Stainless steel is often chosen for its corrosion resistance and durability. Confirm adherence to plumbing or PEX standards when necessary and verify manufacturer SKUs for exact matches.

Before making a purchase, consider packaging and ordering details. Many clamps come in bags of 100. Make sure the Oetiker Inc. part number and supplier listing match the quantity, material, range, and band width you need.

How To Install Stepless Ear Clamps For Reliable Service

A hose assembly will last longer when the clamp is sized, positioned, and crimped correctly. Use safe Stepless Ear Clamp installation steps, choose the correct crimping tool, and keep enough clamps on hand to avoid repair or production delays.

Proper Clamping Procedure

Start by assembling the hose and fitting. Position the clamp so the ear is accessible. Use a dedicated ear clamping tool to seat the clamp and avoid twisting the band. With dual-ear designs, crimp one ear and then the other so compression remains even around the hose.

The target crimp should reduce the clamp ear by at least 40 percent. A properly sized clamp will not force the ear to fully close. After crimping, inspect the band for even contact and check the hose and fitting for damage or gaps.

Safety And Tooling Tips For Clamp Installation

Choose a crimping tool designed for the clamp series so the ear deforms correctly without damaging the hose. Oetiker® ear clamping tools are often used in professional workshops because they help produce repeatable crimps.

Wear eye protection and gloves when crimping clamps to guard against metal burrs and tool slips. Do not use makeshift tools that may create uneven compression, sharp marks, or damaged clamp ears. For repeated production work, bench-mounted or powered crimpers can improve consistency and reduce operator fatigue.

An Asse 1022 Dual Check Valve provides a practical way to support potable-water backflow protection where local code allows it. It helps prevent contaminants and corrosive substances, such as carbonic acid, from entering drinking water. Approved devices are essential for safeguarding potable supplies and following local and national codes.

Asse 1022 Dual Check Valve
Backflow preventer manufacturers, including Watts, make devices that are built to meet ASSE performance requirements and recognized certifications. Depending on the model and application, approvals may include NSF/ANSI 61, UL, FM, or similar third-party listings. Those credentials help verify material safety, pressure durability, and overall assembly performance. Although some authorities require higher-protection assemblies, an Asse 1022 device may be a approved low-hazard option where the local authority permits it.

The Asse 1022 Dual Check Valve is valued for its small footprint, simple installation, and low maintenance costs. This guide compares Asse 1022 devices alongside higher-protection standards, including Asse 1013. It also covers how to select, install, and maintain units to stay compliant with plumbing codes and industry recommendations.

Understanding Backflow And The Role Of Dual Check Valves

Backflow creates a serious risk because water can reverse direction inside a plumbing system. This reverse movement can introduce contaminants into plumbing and compromise drinking-water safety. Water authorities and adopted plumbing codes require backflow protection to help prevent this kind of contamination.

Backflow usually happens because of one of two hydraulic conditions. Backsiphonage occurs when supply pressure falls, creating suction that can draw water in reverse. Backpressure happens when downstream pressure exceeds supply pressure and forces water in the wrong direction. Knowing the difference between backsiphonage and backpressure matters because each condition can call for a different type of protection.

In homes, common cross-connections include irrigation systems, garden hoses, boilers, and chemical injection points. Commercial settings add booster pumps, closed-loop HVAC systems, and process equipment. Without proper protection, these connections can become sources of pollutants.

Dual check valves, including the Asse 1022 model, are designed for low-hazard protection. They are used where reverse flow might affect taste, odor, or water quality without creating a direct health hazard. An Asse 1022 Backflow Preventer can be a compact solution for approved low-hazard applications described by plumbing codes and water authorities.

Correct selection and installation depend on the applicable codes, listings, and standards. ASSE performance requirements, together with ANSI-accredited standards development, help support product acceptance. Installers must follow local plumbing code language, including references such as the 2018 UPC and AWWA M-14, when installing Asse 1022 devices.

Common approved uses may include residential irrigation, HVAC makeup water, and selected commercial low-hazard cross-connections. When the hazard level is higher, authorities typically require a more protective assembly.

Issue	Typical Cause	Recommended Protection
Reverse flow from suction	Main pressure loss from firefighting, broken lines, or supply interruption	Asse 1022 Backflow Preventer for low-hazard use, or air gap where code requires
Reverse flow from downstream pressure	Booster pumps, elevated tanks, or thermal expansion	Asse 1022 where low-hazard is approved, or RPZ where health hazards exist
Risk to potable water quality	Fertilizers, boiler chemicals, cleaning agents, or process liquids	Classify the hazard and use Asse 1022 or a higher-protection assembly

How Backflow Occurs In Plumbing Systems

Backflow is the backward movement of water from any source into the public supply. It may be caused by negative supply pressure, backsiphonage, or excess downstream pressure. Both conditions can introduce contaminants and threaten potable water quality.

Why Dual Check Valves Suit Low-Hazard Protection

Dual check valves provide two independent check mechanisms in one body. That built-in redundancy helps protect low-hazard cross-connections from reverse flow. Asse 1022 devices are tested for low-hazard or nuisance-level risks and are commonly used where the authority allows this type of protection.

Understanding The Asse 1022 Dual Check Valve

An Asse 1022 Dual Check Valve is a compact backflow prevention device used for low-hazard potable-water applications. It uses two independent spring-loaded checks arranged in series. This arrangement prevents reverse flow and provides redundant sealing. It maintains serviceability and reduces contamination risk during pressure shifts or brief backpressure events.

Key Features And How The Valve Works

Spring-loaded check mechanisms help the valve close positively when flow or pressure changes. Many models include serviceable internal parts and replaceable seats. This design reduces maintenance time and lifecycle costs.

Manufacturers produce Asse 1022 units in materials such as bronze, brass, corrosion-resistant alloys, and engineered plastics. Available sizes are designed to match common pipe diameters, pressure ratings, and potable-water system requirements.

Compact bodies, service access, and built-in test ports can make installation and inspection faster. The Asse 1022 Backflow Preventer fits tight spaces where larger assemblies cannot. Properly sized models can meet flow demands for common low-hazard applications.

Standards And Certifications That Support ASSE 1022 Devices

ASSE standards define baseline performance tests, functional requirements, and operating thresholds. Those tests are used to verify dependable operation under defined conditions. Many listed products exceed minimum requirements, which may reduce failure risk and support longer maintenance intervals.

NSF/ANSI 61 certification helps confirm that wetted materials are suitable for drinking water and do not leach harmful contaminants. UL/FM approvals can support confidence in durability, pressure resistance, and stress-tested performance. These listings give engineers, inspectors, and installers additional assurance when specifying equipment.

When combined with ANSI-accredited development, these approvals improve the Asse 1022 Dual Check Valve’s acceptance in plumbing codes and project specifications. For project teams seeking verified material safety and tested performance, ASSE 1022 features, NSF/ANSI 61, and UL/FM marks create a strong compliance package.

ASSE 1022 Compared With ASSE 1013, ASSE 1012, And ASSE 1024

This outline compares common backflow protection options to help match device features with risk and code needs. It explains practical differences among RPZ assemblies, double-check devices, and other dual-check products used in U.S. plumbing systems.

Device selection should start with a clear hazard-level assessment. ASSE 1022 double-check assemblies suit low-hazard services such as irrigation and some HVAC makeup lines. By contrast, Asse 1013 RPZ units are designed for high-hazard cross-connections where contaminants could create a health risk. Asse 1024 covers reduced-pressure principle devices for severe contamination scenarios. Asse 1012 may apply when local rules call for specific dual-check devices or service-line configurations.

How ASSE 1022 Differs From ASSE 1013 And ASSE 1024

ASSE 1022 double-check devices rely on two check valves, and where applicable shutoff valves, to control backflow in low-hazard uses. ASSE 1013 RPZ assemblies add a relief valve that vents to atmosphere under certain pressure conditions, creating a higher protection margin. Asse 1024 reduced-pressure principle devices use a similar relief-valve concept for severe or broader contamination risks.

Testing frequency and complexity differ between these products. Asse 1013 RPZ units commonly require annual testing, post-event checks, and relief-valve verification. ASSE 1022 double-check devices require periodic testing of the check mechanisms, generally with simpler procedures than RPZ assemblies.

When ASSE 1012 And Other Dual-Check Standards Apply

Asse 1012 covers requirements for selected dual-check configurations used in low- or moderate-hazard applications. Choose this standard when local code or the water authority allows a dual-check format but requires a recognized standard beyond ASSE 1022.

Code requirements differ from one jurisdiction to another. Many municipalities following the 2018 UPC require ASSE 1013 RPZ for high-hazard cross-connections. Utilities may accept ASSE 1022 in low-hazard cases or require Asse 1012-certified dual-check devices for certain service lines. Before installation, confirm the required protection level with the local water authority or authority having jurisdiction.

Device Feature	ASSE 1022	ASSE 1013 RPZ	Asse 1024 Reduced Pressure Principle	Asse 1012
Primary use	Low-hazard irrigation and selected HVAC makeup lines	High-hazard cross-connections and health-risk protection	Serious contamination threats requiring reduced-pressure protection	Specific dual-check uses allowed by local authority
Protection level	Lower protection level	High	High hazard	Application-dependent low-to-moderate protection
Relief valve	Not included	Required relief valve	Yes, required	No, unless specified
Inspection requirement	Periodic testing of both checks	Annual and post-event testing with relief verification	Regular testing with relief-valve checks	Periodic testing per authority rules
Typical applications	Low-hazard cross-connections where allowed	High-hazard systems involving toxic or harmful fluids	Serious contamination scenarios with possible health impact	Specific service uses approved by local code or utility
Common code treatment	Permitted where local authority approves low-hazard use	Mandated for high-hazard by many water authorities	Required for serious contamination threats	Applied when the authority requires this dual-check standard

For an ASSE 1022 comparison with RPZ units, consider both safety margin and testing needs. RPZ versus double-check decisions depend on hazard assessment, local code, and water authority rules. If requirements are uncertain, follow the higher protection level required by the authority having jurisdiction.

Installation Maintenance And Code Compliance

Proper Asse 1022 installation begins with thorough planning. Place dual check valves in an easily accessible area and follow the manufacturer’s orientation guidelines. Leave adequate clearance for service access, testing ports, shutoffs, and unions. That clearance allows certified testers or service technicians to reach fittings without unnecessary disassembly.

Use sound piping practices so the installation does not create a new cross-connection risk. Avoid installing devices where downstream cross-connections could undermine the protection. Install shutoffs, unions, drains, and service fittings as required by the manufacturer and local code. Make sure unions and test cocks remain accessible for routine service and backflow testing.

Maintenance schedules are set by local regulations and water authority directives. Many jurisdictions require annual inspection or testing by certified backflow professionals. Clear records of service, repairs, and test results help demonstrate compliance during audits, inspections, and permit reviews.

Certified testers provide documented evidence that satisfies most regulatory requirements. Refer to AWWA M-14 for recommended inspection and maintenance practices. Following these guidelines can reduce downtime and detect wear before leaks or failures occur.

Selecting devices with recognized listings can simplify inspection and approval. Products with ASSE approvals and NSF/ANSI 61 certifications are often easier for inspectors to accept. UL/FM compliance may also be important for commercial, industrial, or fire-protection connections that require third-party recognition.

Before starting, identify the applicable plumbing code edition and local water authority requirements. Certain jurisdictions may require an RPZ rather than a dual check valve. Confirm permitting requirements and verify that the selected Asse 1022 installation meets local standards before work begins.

Establish a consistent record-keeping routine. Store manufacturer cut sheets, test certificates, and repair invoices with a map of the device location. This makes future inspections easier and supports clear compliance during regulatory reviews.

Product Selection Guidance And Where To Buy

Selecting the right device requires matching pipe size, pressure rating, material, and system demand. Make sure the Asse 1022 Dual Check Valve fits the pipe diameter and peak flow. Check pressure ratings against maximum working pressure, surge conditions, and site-specific operating conditions.

Material compatibility is essential for potable water systems. Choose brass, bronze, or NSF/ANSI 61-certified plastics to avoid corrosion or leaching. Check manufacturer data for chemical resistance, especially if local water chemistry is aggressive or unusual.

Verifying certifications can make approval and inspection easier. Confirm that the product lists ASSE 1022 compliance and NSF/ANSI 61 certification. If local codes demand UL or FM approval, confirm those marks before purchase.

Supplier reputation matters when purchasing an ASSE 1022 device. Authorized dealers provide genuine parts, documentation, and warranty support. Installation Parts Supply is a reliable distributor that stocks certified units and can assist with model selection.

Warranty coverage and pricing rules can affect the final purchase cost. Review manufacturer warranty limits and any MAP rules that hide prices online. Some suppliers show final pricing only in the cart while still preserving warranty coverage through authorized sales channels.

Choose Materials

• Match pipe size and flow to the Asse 1022 Dual Check Valve model.
• Use NSF/ANSI 61-certified components for potable-water systems whenever required or available.
• Verify pressure rating and surge tolerance for the Asse 1022 Backflow Preventer.

How To Choose A Supplier

• Purchase from certified or authorized dealers so documentation is available for inspections.
• Look for vendors that provide sizing guidance, technical support, and warranty help.
• Installation Parts Supply often provides certified stock and model guidance.

Buying Factor	What to Check	Reason It Matters
Pipe size and flow	Pipe diameter, GPM requirements, model sizing chart	Prevents pressure loss and ensures proper operation
Material	Brass, bronze, or NSF/ANSI 61-certified plastics	Protects potable water quality and resists corrosion
Pressure and surge capacity	Manufacturer pressure limits and site surge conditions	Ensures safety under normal and peak conditions
Compliance markings	ASSE listing, NSF/ANSI 61, and UL/FM marks where needed	Simplifies permitting and meets code requirements
Supplier	Supplier reputation, product authenticity, and technical help	Reduces risk of counterfeit parts and improves after-sale support
Warranty & Pricing	Manufacturer warranty details, MAP pricing policies	Helps buyers understand total cost and warranty protection

Final Thoughts

ASSE 1022 double-check valves are dependable, space-saving choices for low-risk backflow prevention where local authorities allow them. An Asse 1022 Dual Check Valve uses two spring-loaded check mechanisms and approved materials that may meet NSF/ANSI 61 and ASSE requirements. This helps reduce contamination risk in approved uses such as irrigation systems and certain HVAC makeup lines.

Choosing the right device depends on hazard level and code compliance. An Asse 1022 Backflow Preventer is appropriate for low-hazard scenarios where it is allowed. For high-hazard applications, authorities may require ASSE 1013, ASSE 1024, or another reduced-pressure assembly. Correct selection can simplify permitting, reduce rework, and improve potable-water protection.

For backflow-prevention compliance, follow manufacturer instructions and local plumbing-code requirements. Where applicable, this may include the 2018 UPC, local amendments, and water authority rules. Buy certified products from trusted suppliers or authorized dealers. Confirm ASSE listings, NSF/ANSI 61 certification, and UL or FM approvals when those marks are required.

Reliable backflow protection depends on correct selection, accurate installation, and routine maintenance. When supported by certified devices and qualified testers, these steps help protect potable water. They also make regulatory acceptance, inspection, and documentation easier. Following these practices helps an Asse 1022 Dual Check Valve or other approved backflow solution perform reliably over time.
