Stepless Ear Clamps deliver a unique solution for hose connections, ensuring a tight seal. 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.
Pinch Clamp Size Chart
Stepless Ear Clamps are common in automotive, manufacturing, and marine hose assemblies where a dependable seal matters. They are also important in plumbing, PEX tubing installations, 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 stepless ear clamps, such as Oetiker® Group 167 parts, are sold in quantities of 100. 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
Stepless Ear Clamps provide a simple, dependable solution for hose connections. The continuous band helps apply even compression around the full hose circumference. This uniform pressure reduces high-stress points and promotes long-term seal integrity.
Uniform Compression And Leak Prevention
Even radial pressure is essential 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. Some models meet ASTM-related guidelines for plumbing and PEX installations, ensuring long-term reliability.
How Smooth Edges Help Protect Hose Materials
Narrow band width and burr-free edges limit abrasion during installation and service. 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.

| Design Feature | Practical Benefit | Typical Application |
|---|---|---|
| Consistent clamping pressure | More consistent sealing force and reduced leak risk | Coolant hoses, fuel lines, and plumbing tubing |
| Rust-resistant construction | Improved lifespan in marine, outdoor, or damp areas | Marine fittings, outdoor equipment |
| Burr-free edges | Less hose abrasion, reduced puncture risk | Flexible hoses, rubber and PEX tubing |
| Stepless Ear Clamps | Uniform grip around the hose circumference | Applications requiring reliable hose retention |
| Oetiker clamp design | Trusted clamp engineering for repeated installations | OEM and aftermarket installations |
Selecting The Correct Stepless Ear Clamp Size
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, limits hose damage, and boosts service longevity. Here are simple steps to help you make the right choice and ensure a perfect fit.
Measure the hose outside diameter only after the fitting has been fully seated inside the hose. Record the assembled outside diameter in inches or millimeters. Opt for a clamp whose range has your hose O.D. in the middle for even pressure.
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.
Interpreting a Pinch Clamp Size Chart involves examining minimum and maximum closure diameters and aligning series details with your application. 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. 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. 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.
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.
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. For dual-ear designs, compress the first ear, then the second to obtain uniform compression around the hose.
Target ear deformation should produce clamp ears reduction of 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 tools are often used in professional workshops because they help produce repeatable crimps.
Wear eye protection and gloves when crimping clamps to guard against metal burrs and tool slips. 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.
Buying Quantities And Packaging Details
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.
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 | Example Bag Weight | Notes For Buyers |
|---|---|---|---|
| Small Stepless Ear Clamp | 100 per bag | about 2 lb | Confirm O.D. range and material; keep spares for repairs |
| Medium Stepless Ear Clamp | 100-piece bag | ~3 lb | Match bag quantities to expected usage and production timing |
| Stepless Ear Clamp, large | Bag of 100 | ~4 lb | Confirm SKU, size range, and ear reduction requirement |
| Ear clamp installation tool | one tool per package | about 1.5 lb | Use the correct tool to avoid uneven deformation and damaged clamps |
