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.
Oetiker Inc. is a well-known manufacturer of Oetiker Clamp products, including the Stepless® 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 Hose Fittings Benefit From Stepless Ear Clamps
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.
Leak Prevention Through Uniform Compression
A reliable hose seal depends on even radial pressure around the connection. Unlike some worm-gear clamps, Stepless Ear Clamps help avoid pressure gaps and uneven compression. Engineers frequently select 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 construction delivers 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 limit abrasion during installation and service. A burr-free Oetiker Clamp ensures minimal cutting into flexible tubing while maintaining firm retention. This combination lowers the risk of hose failure and extends its service life.
| Feature | Main Benefit | Frequent Use |
|---|---|---|
| Consistent clamping pressure | Even sealing force, fewer leaks | Coolant hoses, fuel lines, and plumbing tubing |
| Corrosion resistant | Long service life in wet or salty environments | Marine fittings, outdoor equipment |
| Smooth clamp edges | Less hose abrasion, reduced puncture risk | Flexible hoses, rubber and PEX tubing |
| Stepless Ear Clamps | Step-free band design for steady retention | Applications requiring reliable hose retention |
| Oetiker Clamp | Proven designs and industry acceptance | OEM and aftermarket installations |
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. 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. 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 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.
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.
Material and specification choices impact longevity and compliance. Stainless steel is commonly selected because it resists corrosion and holds up well in demanding environments. 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 clamps come in bags of 100. Make sure the Oetiker Inc. part number and supplier listing match the quantity, material, range, and band width you need.
Installation And Best Practices For Long-Term 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.
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. A dedicated ear clamping tool helps crimp the ear without twisting, distorting, or damaging 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. 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 high-volume operations, consider bench-mounted or powered crimpers to standardize force and reduce operator fatigue.
Buying Quantities And Packaging Details
Many industrial suppliers package Stepless Ear Clamps in 100-piece bags. Buying by bag keeps inventory steady for routine maintenance and production needs.
Before ordering, check the SKU, bag weight, clamp range, material, and series details. Installation Parts Supply offers common clamp sizes and related tools; verify part numbers and order spare clamps to cover rework or replacements.

Final Thoughts
For dependable hose fittings, Stepless Ear Clamps offer strong advantages in sealing consistency and hose protection. Their uniform compression helps reduce leaks, hose damage, and uneven stress around the fitting. This is true across various sectors, including automotive, marine, industrial, plumbing, and PEX applications. The use of stainless steel in Oetiker Clamps supports long-lasting corrosion resistance and consistent performance.
For those purchasing and installing, the key points are clear. Measure the assembled hose outside diameter accurately before choosing a clamp. It’s also important to refer to a pinch clamp size chart and choose a clamp with a range that matches the O.D. Proper use of an ear clamping tool is necessary to achieve at least 40% ear reduction. That crimping target helps produce the intended clamping force and sealing performance.
When buying clamps, verify specifications such as band thickness, band width, ear width, and diameter range. Many prefer Oetiker Inc. Stepless® Ear Clamps, such as Group 167 with a 7mm band width. These are available in bulk packaging of 100 per bag.
