For hose connections that need a dependable seal, Stepless Ear Clamps are a purpose-built fastening choice. Their design uses a continuous band without steps or steps. Compared with many traditional clamp styles, this design helps reduce pressure points, hose distortion, and leak potential.
Stepless Ear Clamp
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. 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 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 Are Ideal 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.
Uniform Clamping Pressure And Fewer Leaks
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 choose Oetiker Clamp products for their consistent clamping force, which is critical for PEX, coolant, or fuel lines.
Durability And Corrosion Resistance
Stainless steel construction offers robust corrosion resistance in harsh environments. Automotive, marine, and industrial systems depend on the durability of quality Stepless Ear Clamps. Some models meet ASTM-related guidelines for plumbing and PEX installations, ensuring long-term reliability.
How Smooth Edges Help Protect Hose Materials
A narrow band and smooth, burr-free edges help reduce rubbing, cutting, and abrasion during use. 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 helps improve its service life.

| Clamp Feature | Practical Benefit | Common Application |
|---|---|---|
| Consistent clamping pressure | Balanced pressure with fewer potential leak paths | Fuel systems, cooling lines, and PEX tubing |
| Stainless corrosion protection | Improved lifespan in marine, outdoor, or damp areas | Marine lines and exposed equipment |
| Smooth clamp edges | Lower abrasion risk during installation and service | Soft hose materials and flexible tubing |
| Continuous-band ear clamps | Step-free band design for steady retention | High-retention applications |
| Oetiker Clamp | Proven designs and industry acceptance | Factory assembly and repair work |
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. Proper Stepless Ear Clamp selection prevents leaks, limits hose damage, and supports service longevity. The following steps help narrow the size range and improve the chance of a secure, long-lasting fit.
To measure hose O.D., take the measurement after the fitting is fully inserted. 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. If the Oetiker Inc. spec ranges from 1.547″–1.673″ (39.3mm–42.5mm), select a clamp that positions your measured O.D. near the midpoint. That sizing approach helps avoid clamps that are too loose or too aggressively compressed.
A Pinch Clamp Size Chart should be read by comparing the minimum and maximum diameter range with the actual assembled hose size. 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 instance, the 167 Series Stepless® Ear Clamps have ear width of 10.0mm, band width of 7mm, and band thickness of 0.6mm. The clamp ear should reduce by at least 40% during crimping so adequate clamping force is achieved.
Material and specification choices affect 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.
How To Install Stepless Ear Clamps For Reliable Service
A hose assembly will last longer when the clamp is sized, positioned, and crimped correctly. 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. Use a dedicated ear clamping tool to seat the clamp and avoid twisting the band. For dual-ear designs, compress the first ear, then the second to obtain uniform compression around the hose.
Target ear deformation should produce clamp ears reduction of at least 40 percent. A properly sized clamp will not force the ear to fully close. 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.
Wear eye protection and gloves when crimping clamps to guard against metal burrs and tool slips. 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.
Quantity And Packaging Notes For Buyers
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.
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.
| Clamp Item | Usual Package | Approximate Bag Weight | Buyer Notes |
