These clamps are widely used 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. As one example, Oetiker® 16705828 fits 1.547″–1.673″ / 39.3 mm–42.5 mm diameter ranges and is commonly supplied 100 per bag. Each bag weighs approximately 4 lbs, simplifying inventory management for buyers.
Why Stepless Ear Clamps Are Ideal For Hose Fittings
For many hose assemblies, Stepless Ear Clamps provide a simple and reliable sealing method. Their continuous band design ensures uniform compression around the hose. This uniform pressure lowers high-stress points and supports long-term seal integrity.
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. Engineers frequently choose 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 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 reduce abrasion during installation and service. A burr-free Oetiker Clamp helps provide minimal cutting into flexible tubing while maintaining firm retention. This combination lowers the risk of hose failure and extends its service life.

| Feature | Practical Benefit | Common Application |
|---|---|---|
| Uniform compression | Even sealing force, fewer leaks | Fuel lines, coolant hoses, PEX tubing |
| Stainless corrosion protection | Better durability where moisture or salt is present | Marine lines and exposed equipment |
| Burr-free edges | Less hose abrasion, reduced puncture risk | Soft hose materials and flexible tubing |
| Step-free ear clamps | Continuous band for consistent grip | Applications requiring reliable hose retention |
| Oetiker clamp design | Proven designs and industry acceptance | Original equipment and replacement applications |
How To Choose A Stepless Ear Clamp Using A Pinch Clamp Size Chart
Choosing the right clamp begins 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. 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. Write down the assembled outside diameter in either inches, millimeters, or both. 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. 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.
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. 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 commonly selected because it resists corrosion and holds up well in demanding environments. 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. Ensure part numbers from Oetiker Inc. and suppliers match your needs for correct quantities and appropriate band width.
How To Install Stepless Ear Clamps For Reliable Service
Proper installation is critical 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.
Proper Clamping Procedure
Begin by fully inserting the fitting into the hose. 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
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.
When crimping clamps, wear gloves and eye protection to reduce risk from slips, edges, or metal fragments. 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
Many industrial suppliers package Stepless Ear Clamps in 100-piece bags. Buying by bag keeps inventory steady for routine maintenance and production needs.
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.
| Item | Usual Package | Approximate Bag Weight | Notes For Buyers |
|---|---|---|---|
| Small-size stepless clamp | Bag of 100 | approximately 2 lb | Verify range, series, and material before ordering spares |
| Stepless Ear Clamp, medium | 100-piece bag | approximately 3 lb | Match bag quantities to expected usage and production timing |
| Large-size stepless clamp | 100-piece bag | about 4 lb | Review part number, clamp range, and crimping specification |
| Ear clamp installation tool | 1 per box | about 1.5 lb | Use the correct tool to avoid uneven deformation and damaged clamps |
