For hose connections that need a secure seal, Stepless Ear Clamps are a smart fastening choice. Their design includes a continuous band without steps or steps. This eliminates pressure points and greatly reduces leak risk compared to traditional clamps.
Stepless Ear Clamps
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. 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. 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. 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 deliver a straightforward, dependable solution for hose connections. The continuous band helps apply even compression around the full hose circumference. This uniform pressure minimizes high-stress points and promotes long-term seal integrity.
Uniform Compression And Leak Prevention
Even radial pressure is important 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 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.
Reduced Hose Damage And Burr-Free Edges
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 extends its service life.

| Feature | Main Benefit | Typical Application |
|---|---|---|
| Consistent clamping pressure | Balanced pressure with fewer potential leak paths | Fuel systems, cooling lines, and PEX tubing |
| Stainless corrosion protection | Long service life in wet or salty environments | Boat systems, outdoor machinery, and wet-area fittings |
| Burr-free edges | Less hose abrasion, reduced puncture risk | Flexible hoses, rubber and PEX tubing |
| Stepless Ear Clamps | Step-free band design for steady retention | Demanding hose assemblies |
| Oetiker-style clamp | Trusted clamp engineering for repeated installations | Factory assembly and repair work |
Selecting The Correct Stepless Ear Clamp Size
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.
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. That sizing approach helps avoid clamps that are too loose or too aggressively compressed.
Interpreting a Pinch Clamp Size Chart involves 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 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 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 clamps come in bags of 100. Make sure the Oetiker Inc. part number and supplier listing match the quantity, material, range, and band width you need.
Installation And Best Practices For Long-Term 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
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.
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.
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.
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.
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 | Usual Package | Sample Shipping Weight | Buyer Notes |
|---|---|---|---|
| Small Stepless Ear Clamp | Bag of 100 | ~2 lb | Confirm O.D. range and material; keep spares for repairs |
| Stepless Ear Clamp, medium | Bag of 100 | about 3 lb | Order by bag quantity to match production schedules |
| Large Stepless Ear Clamp | 100-piece bag | about 4 lb | Review part number, clamp range, and crimping specification |
| Clamp crimping tool | one tool per package | about 1.5 lb | Select a tool matched to the clamp series for consistent crimping |
