For hose connections that need a secure seal, Stepless Ear Clamps are a smart fastening choice. Because the band is continuous and step-free, pressure is distributed more evenly around the hose. This eliminates pressure points and greatly reduces leak risk compared to traditional clamps.

These clamps are essential 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.
Oetiker Inc. is a trusted 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. Each bag weighs approximately 4 lbs, simplifying inventory management for buyers.
Why Hose Fittings Benefit From Stepless Ear Clamps
Stepless Ear Clamps provide a simple, 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.
Uniform Clamping Pressure And Fewer Leaks
Even radial pressure is essential for preventing leaks. Stepless Ear Clamps deliver 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. Automotive, marine, and industrial systems depend on the durability of quality Stepless Ear Clamps. Certain models may align with ASTM-related plumbing or PEX requirements, supporting reliable long-term service where specifications apply.
How Smooth Edges Help Protect Hose Materials
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. Together, smooth edges and even pressure help reduce premature hose failure and extend service life.

| Design Feature | Main Benefit | Common Application |
|---|---|---|
| Even radial compression | Even sealing force, fewer leaks | Fuel lines, coolant hoses, PEX tubing |
| Rust-resistant construction | Better durability where moisture or salt is present | Boat systems, outdoor machinery, and wet-area fittings |
| Burr-free edges | Lower abrasion risk during installation and service | Rubber tubing, flexible hose, and PEX lines |
| Continuous-band ear clamps | Uniform grip around the hose circumference | Demanding hose assemblies |
| Oetiker-style 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. When the correct Stepless Ear Clamp is chosen, the connection is less likely to leak, crush the hose, or fail early. Here are straightforward steps to help you make the right choice and ensure a perfect fit.
To measure hose O.D., take the measurement after the fitting is fully inserted. Write down the assembled outside diameter in either inches, millimeters, or both. 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. This avoids both under- and over-compression.
Interpreting a Pinch Clamp Size Chart requires 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.
Use the chart to compare ear width, band width, and band thickness. For instance, the 167 Series Stepless® Ear Clamps have ear width of 10.0mm, band width of 7mm, and band thickness of 0.6mm. 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 making a purchase, consider packaging and ordering details. 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.
How To Install Stepless Ear Clamps For Reliable Service
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. Position the clamp so the ear is accessible. A dedicated ear clamping tool helps crimp the ear without twisting, distorting, or damaging 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. When the clamp is correctly sized, the ear should not have to close completely to achieve sealing force. 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.
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
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 related tools; verify part numbers and order spare clamps to cover rework or replacements.
