Stepless Ear Clamps deliver a unique solution for hose connections, helping create a tight seal. Because the band is continuous and step-free, pressure is distributed more evenly around the hose. This reduces pressure points and substantially reduces leak risk compared to traditional clamps.
Pinch Clamp Size Chart
Stepless Ear Clamps are common in automotive, industrial, and marine hose assemblies where a dependable seal matters. They are also important in plumbing, PEX tubing installations, and home workshop projects. Most models are made from stainless steel, with Group 167 Stepless® clamps often having a 7 mm band width for consistent performance.
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. 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 Work Well For Hose Fittings
For many hose assemblies, Stepless Ear Clamps provide a simple and reliable sealing method. Their continuous band design ensures uniform compression around the hose. This uniform pressure minimizes high-stress points and supports long-term seal integrity.
Leak Prevention Through Uniform Compression
Even radial pressure is critical 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 provides robust corrosion resistance in harsh environments. Quality Stepless Ear Clamps are useful in automotive, marine, and industrial systems where parts must withstand vibration, moisture, and service wear. 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 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 | Benefit | Common Application |
|---|---|---|
| Consistent clamping pressure | More consistent sealing force and reduced leak risk | Fuel lines, coolant hoses, PEX tubing |
| Rust-resistant construction | Long service life in wet or salty environments | Boat systems, outdoor machinery, and wet-area fittings |
| Rounded, hose-safe edges | Lower abrasion risk during installation and service | Flexible hoses, rubber and PEX tubing |
| Step-free ear clamps | Uniform grip around the hose circumference | Demanding hose assemblies |
| Oetiker clamp design | Trusted clamp engineering for repeated installations | Factory assembly and repair work |
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. 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. 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 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. 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.
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. 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 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.
Installation And Best Practices For Long-Term Reliability
A hose assembly will last longer when the clamp is sized, positioned, and crimped correctly. Use safe Stepless Ear Clamp installation steps, choose the correct crimping tool, and keep enough clamps on hand to avoid repair or production delays.
Proper Clamping Procedure
Start by assembling the hose and fitting. 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. 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.
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. 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 installation tools, but part numbers should still be verified and spare clamps should be ordered for rework or replacements.
| Product Item | Typical Pack | Example Bag Weight | Ordering Notes |
|---|---|---|---|
| Stepless Ear Clamp, small | 100 per bag | approximately 2 lb | Confirm O.D. range and material; keep spares for repairs |
| Medium-size stepless clamp | Bag of 100 | approximately 3 lb | Buy by bag to support maintenance and production planning |
| Large-size stepless clamp | 100 per bag | about 4 lb | Review part number, clamp range, and crimping specification |
| Clamp crimping tool | 1 per box | ~1.5 lb | Use the correct tool to avoid uneven deformation and damaged clamps |
