For hose connections that need a secure seal, Stepless Ear Clamps are a smart fastening choice. Their design includes a continuous band without breaks or steps. Compared with many traditional clamp styles, this design helps reduce pressure points, hose distortion, and leak potential.
Stepless Ear Clamps
Stepless Ear Clamps are common in automotive, 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. With each bag weighing about 4 lbs, buyers can more easily plan storage, shipping, and inventory control.
Why Stepless Ear Clamps Work Well For Hose Fittings
For many hose assemblies, Stepless Ear Clamps provide a simple and reliable sealing method. The continuous band helps apply even compression around the full hose circumference. By reducing localized stress, the clamp helps protect the hose and maintain a more durable seal.
Uniform Compression And Leak Prevention
Even radial pressure is critical for preventing leaks. Stepless Ear Clamps apply 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.
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. Certain models may align with ASTM-related plumbing or PEX requirements, supporting reliable long-term service where specifications apply.
Reduced Hose Damage And Burr-Free Edges
Narrow band width and burr-free edges limit abrasion during installation and service. 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 supports its service life.

| Clamp Feature | Benefit | Frequent Use |
|---|---|---|
| Even radial compression | Even sealing force, fewer leaks | Coolant hoses, fuel lines, and plumbing tubing |
| Rust-resistant construction | Better durability where moisture or salt is present | Boat systems, outdoor machinery, and wet-area fittings |
| Smooth clamp edges | Lower abrasion risk during installation and service | Flexible hoses, rubber and PEX tubing |
| Continuous-band ear clamps | Uniform grip around the hose circumference | Demanding hose assemblies |
| Oetiker Clamp | Proven designs and industry acceptance | Original equipment and replacement applications |
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. Proper Stepless Ear Clamp selection reduces leaks, minimizes hose damage, and boosts service longevity. The following steps help narrow the size range and improve the chance of a secure, long-lasting 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. 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. This reduces both under- and over-compression.
A Pinch Clamp Size Chart should be read by comparing the minimum and maximum diameter range with the actual assembled hose size. 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. The clamp ear should reduce by at least 40% during crimping so adequate clamping force is achieved.
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. Ensure part numbers from Oetiker Inc. and suppliers match your needs for correct quantities and appropriate band width.
Best Installation Practices For Long-Term Clamp Reliability
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.
Recommended Clamping Steps
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. 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 installation, inspect the band, hose, and fitting for even contact, visible gaps, cuts, or other damage.
Recommended Tools And Safety Tips
Use purpose-built crimping tools sized for your clamp series to ensure correct deformation without nicking the hose. Oetiker® ear clamping tool models are common choices in professional shops for reliable results.
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 high-volume operations, consider bench-mounted or powered crimpers to standardize force and reduce operator fatigue.
Packaging And Quantity 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.
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 |
|---|---|---|---|
| Stepless Ear Clamp, small | Bag of 100 | approximately 2 lb | Verify range, series, and material before ordering spares |
| Medium Stepless Ear Clamp | 100 per bag | approximately 3 lb | Match bag quantities to expected usage and production timing |
| Large-size stepless clamp | 100-piece bag | approximately 4 lb | Verify SKU and size; check clamp ears reduction spec |
| Ear clamp installation tool | one tool per package | ~1.5 lb | Use the correct tool to avoid uneven deformation and damaged clamps |
