Stepless Ear Clamps offer a unique solution for hose connections, helping create a tight seal. 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.
Oetiker Inc
Stepless Ear Clamps are common in vehicle, industrial, and boat-related hose assemblies where a dependable seal matters. 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. Each bag weighs approximately 4 lbs, simplifying inventory management for buyers.
Why Stepless Ear Clamps Work Well For Hose Fittings
Stepless Ear Clamps deliver a straightforward, dependable solution for hose connections. Their continuous band design ensures 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
A reliable hose seal depends on even radial pressure around the connection. Stepless Ear Clamps create uniform pressure, avoiding the gaps that worm-gear clamps often create. Engineers frequently specify Oetiker Clamp products for their consistent clamping force, which is critical for PEX, coolant, or fuel lines.
Durability And Corrosion 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. Certain models may align with ASTM-related plumbing or PEX requirements, supporting reliable long-term service where specifications apply.
Burr-Free Edges And Reduced Hose Damage
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. Together, smooth edges and even pressure help reduce premature hose failure and extend service life.

| Clamp Feature | Benefit | Frequent Use |
|---|---|---|
| Uniform compression | More consistent sealing force and reduced leak risk | Coolant hoses, fuel lines, and plumbing tubing |
| Corrosion resistant | Better durability where moisture or salt is present | Marine lines and exposed equipment |
| Burr-free edges | Reduced cutting, rubbing, and hose damage | Flexible hoses, rubber and PEX tubing |
| Step-free ear clamps | Step-free band design for steady retention | High-retention applications |
| Oetiker Clamp | Recognized performance and broad industry use | Original equipment and replacement applications |
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 reduces leaks, minimizes hose damage, and supports service longevity. 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. 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. 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. 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 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. Follow safe installation steps for Stepless Ear Clamp, use the right tools, and plan quantities to avoid delays in maintenance or production.
Proper Clamping Procedure
Begin by fully inserting the fitting into the hose. Place the clamp where it can seal properly and where the ear can be reached by the crimping tool. 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.
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 installation, inspect the band, hose, and fitting for even contact, visible gaps, cuts, or other damage.
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.
Quantity And Packaging 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.
| Item | Common Pack | Example Bag Weight | Notes For Buyers |
|---|---|---|---|
| Small Stepless Ear Clamp | 100 per bag | about 2 lb | Check the O.D. range and material, then stock extras for repairs |
| Medium Stepless Ear Clamp | 100 per bag | ~3 lb | Buy by bag to support maintenance and production planning |
| Stepless Ear Clamp, large | 100 per bag | about 4 lb | Review part number, clamp range, and crimping specification |
| Clamp crimping tool | one tool per package | approximately 1.5 lb | Select a tool matched to the clamp series for consistent crimping |
