For hose connections that need a firm seal, Stepless Ear Clamps are a reliable fastening choice. 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.
Stepless Ear Clamp
Stepless Ear Clamps are common in automotive, industrial, and marine hose assemblies where a dependable seal matters. They also serve plumbing work, PEX tubing jobs, repair tasks, 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 Stepless Ear Clamps Work Well For Hose Fittings
Stepless Ear Clamps offer a practical, dependable solution for hose connections. Their continuous band design creates 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
Even radial pressure is important for preventing leaks. 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.
Corrosion Resistance And Long-Term Durability
Stainless steel construction offers 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.
Reduced Hose Damage And Burr-Free Edges
Narrow band width and burr-free edges reduce abrasion during installation and service. A burr-free Oetiker Clamp helps provide minimal cutting into flexible tubing while maintaining firm retention. This combination reduces the risk of hose failure and supports its service life.

| Design Feature | Main Benefit | Frequent Use |
|---|---|---|
| Uniform compression | Even sealing force, fewer leaks | Fuel lines, coolant hoses, PEX tubing |
| Rust-resistant construction | Better durability where moisture or salt is present | Marine lines and exposed equipment |
| Rounded, hose-safe edges | Reduced cutting, rubbing, and hose damage | Flexible hoses, rubber and PEX tubing |
| Continuous-band ear clamps | Step-free band design for steady retention | High-retention applications |
| Oetiker clamp design | Trusted clamp engineering for repeated installations | 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 practical steps to help you make the right choice and ensure a perfect 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. Opt for a clamp whose range has your hose O.D. in the middle for even pressure.
The 167 Series Stepless® Ear Clamps serve as a prime example. 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. This helps prevent both under- and over-compression.
A Pinch Clamp Size Chart should be read by comparing the minimum and maximum diameter range with the actual assembled hose size. 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 example, 167 Series Stepless® Ear Clamps may list a 10.0mm ear width, 7mm band width, and 0.6mm band thickness. The clamp ear should reduce by at least 40% during crimping so adequate clamping force is achieved.
Material and specification choices influence longevity 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 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
Proper installation is essential to a hose assembly’s longevity. Use safe Stepless Ear Clamp installation steps, choose the correct crimping tool, and keep enough clamps on hand to avoid repair or production delays.
Correct Stepless Ear Clamp 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.
Target ear deformation should produce clamp ears reduction of at least 40 percent. When the clamp is correctly sized, the ear should not have to close completely to achieve sealing force. After installation, inspect the band, hose, and fitting for even contact, visible gaps, cuts, or other damage.
Recommended Tools And Safety Tips
Use purpose-built crimping tools sized for your clamp series to ensure correct deformation without nicking the hose. Oetiker® ear clamping tools are often used in professional workshops because they help produce repeatable crimps.
When crimping clamps, wear gloves and eye protection to reduce risk from slips, edges, or metal fragments. 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.
Buying Quantities And Packaging Details
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.
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 | Sample Shipping Weight | Notes For Buyers |
|---|---|---|---|
| Small-size stepless clamp | Bag of 100 | about 2 lb | Check the O.D. range and material, then stock extras for repairs |
| Stepless Ear Clamp, medium | 100-piece bag | approximately 3 lb | Buy by bag to support maintenance and production planning |
| Stepless Ear Clamp, large | 100 per bag | about 4 lb | Review part number, clamp range, and crimping specification |
| Ear clamp installation tool | 1 per box | about 1.5 lb | Choose tool rated for clamp series to ensure repeatable crimps |
