For hose connections that need a secure seal, Stepless Ear Clamps are a purpose-built fastening choice. Because the band is continuous and step-free, pressure is distributed more evenly around the hose. Compared with many traditional clamp styles, this design helps reduce pressure points, hose distortion, and leak potential.

These clamps are essential in various applications, including automotive systems, industrial machinery, and marine lines. They are also important in plumbing, PEX tubing installations, and home workshop projects. Many models use stainless steel construction, and Group 167 Stepless® clamps commonly feature a 7 mm band width to help provide consistent compression.
Among clamp manufacturers, Oetiker Inc. is strongly associated with Oetiker Clamp products and the Stepless® clamp family. Many Oetiker® Group 167 stepless ear clamps are packaged in 100-piece quantities for convenient ordering. For instance, Oetiker® 16705828, suitable for 1.547″–1.673″ / 39.3 mm–42.5 mm diameters, is packaged 100 per bag. With each bag weighing about 4 lbs, buyers can more easily plan storage, shipping, and inventory control.
Why Hose Fittings Benefit From Stepless Ear Clamps
Stepless Ear Clamps offer a practical, dependable solution for hose connections. Their continuous band design ensures uniform compression around the hose. This uniform pressure lowers high-stress points and promotes long-term seal integrity.
Leak Prevention Through Uniform Compression
A reliable hose seal depends on even radial pressure around the connection. Unlike some worm-gear clamps, Stepless Ear Clamps help avoid pressure gaps and uneven compression. Engineers frequently specify Oetiker Clamp products for their consistent clamping force, which is critical for PEX, coolant, or fuel lines.
Durable Stainless Construction And Rust Resistance
Stainless steel helps these clamps resist corrosion in wet, salty, hot, or demanding environments. Automotive, marine, and industrial systems depend on the durability of quality Stepless Ear Clamps. Certain models may align with ASTM-related plumbing or PEX requirements, supporting reliable long-term service where specifications apply.
How Smooth Edges Help Protect Hose Materials
A narrow band and smooth, burr-free edges help reduce rubbing, cutting, and abrasion during use. A burr-free Oetiker Clamp supports minimal cutting into flexible tubing while maintaining firm retention. Together, smooth edges and even pressure help reduce premature hose failure and extend service life.

| Design Feature | Main Benefit | Typical Application |
|---|---|---|
| Uniform compression | Balanced pressure with fewer potential leak paths | Coolant hoses, fuel lines, and plumbing tubing |
| Rust-resistant construction | Long service life in wet or salty environments | Marine fittings, outdoor equipment |
| Rounded, hose-safe edges | Reduced cutting, rubbing, and hose damage | Rubber tubing, flexible hose, and PEX lines |
| Continuous-band ear clamps | Step-free band design for steady retention | Applications requiring reliable hose retention |
| Oetiker clamp design | Recognized performance and broad industry use | Original equipment and replacement applications |
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.
Quantity And Packaging Notes For Buyers
Industrial suppliers typically sell Stepless Ear Clamps in bag quantity packs of 100. Purchasing by the bag helps maintain inventory for repairs, maintenance, assembly work, and production runs.
Check bag weight and SKU before ordering to confirm size range and material. Installation Parts Supply offers common clamp sizes and related tools; verify part numbers and order spare clamps to cover rework or replacements.
| Item | Typical Pack | Example Bag Weight | Buyer Notes |
|---|---|---|---|
| Stepless Ear Clamp, small | 100-piece bag | approximately 2 lb | Confirm O.D. range and material; keep spares for repairs |
| Medium-size stepless clamp | 100-piece bag | ~3 lb | Match bag quantities to expected usage and production timing |
| Stepless Ear Clamp, large | 100-piece bag | about 4 lb | Confirm SKU, size range, and ear reduction requirement |
| Ear clamping tool | 1 per box | ~1.5 lb | Select a tool matched to the clamp series for consistent crimping |
