Stepless Ear Clamps provide a highly practical solution for hose connections, helping create a tight seal. Because the band is continuous and step-free, pressure is distributed more evenly around the hose. This reduces pressure points and greatly reduces leak risk compared to traditional clamps.

These clamps are highly useful in various applications, including automotive systems, industrial machinery, and marine lines. They are also important in plumbing, PEX tubing installations, and home workshop projects. Most models are made from stainless steel, with Group 167 Stepless® clamps often having a 7 mm band width for consistent performance.
Oetiker Inc. is a well-known manufacturer of Oetiker Clamp products, including the Stepless® 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 Stepless Ear Clamps Are Ideal For Hose Fittings
Stepless Ear Clamps offer a practical, dependable solution for hose connections. Their continuous band design ensures uniform compression around the hose. By reducing localized stress, the clamp helps protect the hose and maintain a more durable seal.
Uniform Compression And Leak Prevention
A reliable hose seal depends on even radial pressure around the connection. Stepless Ear Clamps deliver uniform pressure, avoiding the gaps that worm-gear clamps often create. For PEX tubing, coolant hoses, and fuel lines, engineers often choose Oetiker Clamp products because consistent clamping force is especially important.
Corrosion Resistance And Long-Term Durability
Stainless steel helps these clamps resist corrosion in wet, salty, hot, or demanding environments. Automotive, marine, and industrial systems gain from the durability of quality Stepless Ear Clamps. Some models meet ASTM-related guidelines for plumbing and PEX installations, ensuring long-term reliability.
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 can hold flexible tubing securely without aggressively cutting into the hose surface. This combination minimizes the risk of hose failure and helps improve its service life.
| Feature | Benefit | Frequent Use |
|---|---|---|
| Uniform compression | Balanced pressure with fewer potential leak paths | Coolant hoses, fuel lines, and plumbing tubing |
| Stainless corrosion protection | Better durability where moisture or salt is present | Boat systems, outdoor machinery, and wet-area fittings |
| Burr-free edges | Reduced cutting, rubbing, and hose damage | Flexible hoses, rubber and PEX tubing |
| Continuous-band ear clamps | Uniform grip around the hose circumference | Demanding hose assemblies |
| Oetiker clamp design | Proven designs and industry acceptance | Original equipment and replacement applications |
Selecting The Correct Stepless Ear Clamp Size
Choosing the right clamp starts with precise measurement and a thorough review of the 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. The following steps help narrow the size range and improve the chance of a secure, long-lasting fit.
To measure hose O.D., take the measurement after the fitting is fully inserted. Record the assembled outside diameter in inches or millimeters. Opt for a clamp whose range has your hose O.D. in the middle for even pressure.
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. This reduces both under- and over-compression.
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. The clamp ear should reduce by at least 40% during crimping so adequate clamping force is achieved.
Material and specification choices affect longevity and compliance. Stainless steel is often chosen for its corrosion resistance and durability. When plumbing or PEX standards apply, confirm the specification and verify the manufacturer SKU before purchasing.
Before placing an order, review the packaging quantity, SKU, and listed size range. Many Stepless Ear Clamps are sold in 100-piece bags. Make sure the Oetiker Inc. part number and supplier listing match the quantity, material, range, and band width you need.
Best Installation Practices For Long-Term Clamp Reliability
A hose assembly will last longer when the clamp is sized, positioned, and crimped correctly. Follow safe installation steps for Stepless Ear Clamp, use the right tools, and plan quantities to avoid delays in maintenance or production.
Correct Stepless Ear Clamp Procedure
Start by assembling the hose and fitting. Place the clamp where it can seal properly and where the ear can be reached by the crimping tool. Use a dedicated ear clamping tool to seat the clamp and avoid twisting the band. For dual-ear designs, compress the first ear, then the second to obtain uniform compression around the hose.
Target ear deformation should produce clamp ears reduction of at least 40 percent. A properly sized clamp will not force the ear to fully close. After installation, inspect the band, hose, and fitting for even contact, visible gaps, cuts, or other damage.
Tools And Safety Tips
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.
Packaging And Quantity 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.
| Clamp Item | Typical Pack | Example Bag Weight | Notes For Buyers |
|---|---|---|---|
| Stepless Ear Clamp, small | 100-piece bag | ~2 lb | Confirm O.D. range and material; keep spares for repairs |
| Medium Stepless Ear Clamp | Bag of 100 | ~3 lb | Match bag quantities to expected usage and production timing |
| Stepless Ear Clamp, large | Bag of 100 | about 4 lb | Confirm SKU, size range, and ear reduction requirement |
| Clamp crimping tool | one tool per package | about 1.5 lb | Choose tool rated for clamp series to ensure repeatable crimps |
