These clamps are highly useful in various applications, including automotive systems, industrial machinery, and marine lines. They also serve plumbing work, PEX tubing jobs, repair tasks, 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 leading manufacturer of Oetiker Clamp products, including the Stepless® family. Many stepless ear clamps, such as Oetiker® Group 167 parts, are sold in quantities of 100. 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 provide a simple, dependable solution for hose connections. The continuous band helps apply even compression around the full hose circumference. This uniform pressure reduces high-stress points and helps preserve long-term seal integrity.
Uniform Clamping Pressure And Fewer Leaks
A reliable hose seal depends on even radial pressure around the connection. Stepless Ear Clamps apply 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.
Durable Stainless Construction And Rust Resistance
Stainless steel construction provides robust corrosion resistance in harsh environments. Quality Stepless Ear Clamps are useful in automotive, marine, and industrial systems where parts must withstand vibration, moisture, and service wear. Some models meet ASTM-related guidelines for plumbing and PEX installations, ensuring long-term reliability.
How Smooth Edges Help Protect Hose Materials
Narrow band width and burr-free edges reduce abrasion during installation and service. A burr-free Oetiker Clamp can hold flexible tubing securely without aggressively cutting into the hose surface. Together, smooth edges and even pressure help reduce premature hose failure and extend service life.
| Feature | Main Benefit | Frequent Use |
|---|---|---|
| Even radial compression | Balanced pressure with fewer potential leak paths | Coolant hoses, fuel lines, and plumbing tubing |
| Corrosion resistant | 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 | Soft hose materials and flexible tubing |
| Step-free ear clamps | Step-free band design for steady retention | High-retention applications |
| Oetiker Clamp | Proven designs and industry acceptance | OEM and aftermarket installations |
How To Select The Right Stepless Ear Clamp And 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. Proper Stepless Ear Clamp selection helps prevent leaks, minimizes hose damage, and improves service longevity. The following steps help narrow the size range and improve the chance of a secure, long-lasting fit.
Measure the hose outside diameter only after the fitting has been fully seated inside the hose. 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. For a listed range such as 1.547″–1.673″ (39.3mm–42.5mm), the measured assembled O.D. should ideally fall near the center of that range. That sizing approach helps avoid clamps that are too loose or too aggressively compressed.
Interpreting a Pinch Clamp Size Chart means examining minimum and maximum closure diameters and aligning series details with your application. Consider ear width, band width, and band thickness to ensure mechanical fit and force 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.
Clamp material and published specifications directly affect service life, compatibility, and compliance. Stainless steel is commonly selected because it resists corrosion and holds up well in demanding environments. Confirm adherence to plumbing or PEX standards when necessary and verify manufacturer SKUs for exact matches.
Before placing an order, review the packaging quantity, SKU, and listed size range. Many Stepless Ear Clamps are sold in 100-piece bags. Ensure part numbers from Oetiker Inc. and suppliers match your needs for correct quantities and appropriate band width.
Installation And Best Practices For Long-Term Reliability
Proper installation is essential to a hose assembly’s longevity. 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
Begin by fully inserting the fitting into the hose. 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. With dual-ear designs, crimp one ear and then the other so compression remains even 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. Avoid improvised tools that create uneven crimps or sharp edges. For repeated production work, bench-mounted or powered crimpers can improve consistency and reduce operator fatigue.
Quantity And Packaging Notes For Buyers
Many industrial suppliers package Stepless Ear Clamps in 100-piece bags. Purchasing by the bag helps maintain inventory for repairs, maintenance, assembly work, and production runs.
Before ordering, check the SKU, bag weight, clamp range, material, and series details. Installation Parts Supply offers common clamp sizes and installation tools, but part numbers should still be verified and spare clamps should be ordered for rework or replacements.
| Product Item | Typical Pack | Sample Shipping Weight | Notes For Buyers |
|---|---|---|---|
| Small Stepless Ear Clamp | 100 per bag | ~2 lb | Check the O.D. range and material, then stock extras for repairs |
| Medium-size stepless clamp | 100 per bag | ~3 lb | Match bag quantities to expected usage and production timing |
| Large Stepless Ear Clamp | 100 per bag | approximately 4 lb | Confirm SKU, size range, and ear reduction requirement |
| Clamp crimping tool | single tool per box | approximately 1.5 lb | Choose tool rated for clamp series to ensure repeatable crimps |
