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. 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 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 Stepless Ear Clamps Work Well For Hose Fittings
Stepless Ear Clamps deliver a straightforward, dependable solution for hose connections. Their continuous band design supports uniform compression around the hose. By reducing localized stress, the clamp helps protect the hose and maintain a more durable seal.
Leak Prevention Through Uniform Compression
Even radial pressure is critical for preventing leaks. 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 delivers 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 minimize abrasion during installation and service. A burr-free Oetiker Clamp can hold flexible tubing securely without aggressively cutting into the hose surface. This combination lowers the risk of hose failure and helps improve its service life.

| Design Feature | Practical Benefit | Common Application |
|---|---|---|
| Even radial compression | More consistent sealing force and reduced leak risk | Coolant hoses, fuel lines, and plumbing tubing |
| Rust-resistant construction | Better durability where moisture or salt is present | Marine lines and exposed equipment |
| Burr-free edges | Less hose abrasion, reduced puncture risk | Rubber tubing, flexible hose, and PEX lines |
| Continuous-band ear clamps | Continuous band for consistent grip | Applications requiring reliable hose retention |
| Oetiker Clamp | Recognized performance and broad industry use | Original equipment and replacement applications |
How To Select The Right Stepless Ear Clamp And Pinch Clamp Size Chart
Choosing the right clamp begins with precise measurement and a thorough review of the Pinch Clamp Size Chart. Proper Stepless Ear Clamp selection reduces leaks, minimizes hose damage, and supports service longevity. 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 make 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 reduces both under- and over-compression.
Interpreting a Pinch Clamp Size Chart means 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 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 impact 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 making a purchase, consider packaging and ordering details. 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.
Best Installation Practices For Long-Term Clamp 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
Start by assembling the hose and fitting. Position the clamp so the ear is accessible. A dedicated ear clamping tool helps crimp the ear without twisting, distorting, or damaging the band. For dual-ear designs, compress the first ear, then the second to obtain uniform compression 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 tool models are common choices in professional shops for reliable results.
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 high-volume operations, consider bench-mounted or powered crimpers to standardize force 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 installation tools, but part numbers should still be verified and spare clamps should be ordered for rework or replacements.
| Clamp Item | Common Pack | Approximate Bag Weight | Notes For Buyers |
|---|---|---|---|
| Small Stepless Ear Clamp | 100 per bag | ~2 lb | Verify range, series, and material before ordering spares |
| Medium Stepless Ear Clamp | Bag of 100 | approximately 3 lb | Buy by bag to support maintenance and production planning |
| Stepless Ear Clamp, large | 100-piece bag | about 4 lb | Verify SKU and size; check clamp ears reduction spec |
| Ear clamping tool | 1 per box | ~1.5 lb | Select a tool matched to the clamp series for consistent crimping |
Trusted Brands And Buying Sources For Oetiker Clamp Products
