Stepless Ear Clamps deliver a specialized solution for hose connections, supporting a tight seal. Because the band is continuous and step-free, pressure is distributed more evenly around the hose. Compared with many traditional clamp styles, this design helps reduce pressure points, hose distortion, and leak potential.

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 Stepless Ear Clamps Work Well For Hose Fittings
Stepless Ear Clamps offer a practical, dependable solution for hose connections. 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 Clamping Pressure And Fewer Leaks
Even radial pressure is critical for preventing leaks. 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. Quality Stepless Ear Clamps are useful in automotive, marine, and industrial systems where parts must withstand vibration, moisture, and service wear. Some models meet ASTM-related guidelines for plumbing and PEX installations, ensuring long-term reliability.
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 supports minimal cutting into flexible tubing while maintaining firm retention. Together, smooth edges and even pressure help reduce premature hose failure and extend service life.

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 improves 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. For best results, choose a clamp range that places the measured hose O.D. near the middle of the listed range.
The 167 Series Stepless® Ear Clamps provide 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. This helps prevent both under- and over-compression.
Interpreting a Pinch Clamp Size Chart means 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 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.
Material and specification choices affect longevity and compliance. Stainless steel is commonly selected because it resists corrosion and holds up well in demanding environments. 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.
How To Install Stepless Ear Clamps For Reliable Service
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.
Recommended Clamping Steps
Start by assembling the hose and fitting. Place the clamp where it can seal properly and where the ear can be reached by the crimping tool. 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.
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 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 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. 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. Buying by bag keeps inventory steady for routine maintenance and production needs.
Check bag weight and SKU before ordering to confirm size range and material. Installation Parts Supply offers common clamp sizes and related tools; verify part numbers and order spare clamps to cover rework or replacements.
