Oetiker 16707160 Ear Clamp 2.5 Inches Stainless Steel

Product Description

The OETIKER 16707160 is a single-ear stepless clamp designed for permanent, vibration-resistant hose connections across a wide range of fluid and pneumatic systems. With a nominal diameter of 2.5 inches, a band width of 7 mm, and a band thickness of 0.6 mm, this clamp creates a uniform 360-degree seal when crimped with a pincer tool. The stainless steel construction resists corrosion in wet, chemical, and outdoor environments. Plumbers, HVAC technicians, and automotive service professionals routinely rely on ear clamps where worm-gear or T-bolt clamps are not suitable for the application.

This clamp is appropriate for residential and light commercial installations where a tamper-evident, one-time permanent connection is required. Typical applications include coolant hose assemblies, PEX tubing connections, low-pressure pneumatic lines, and drain or condensate hose fittings. The 2.5-inch nominal size suits mid-range tubing and pipe outside diameters. Its compact ear profile allows installation in tight spaces where larger clamp styles cannot fit.

Key Features

• Nominal clamp size of 2.5 inches for mid-range hose and tubing applications
• Stainless steel construction for corrosion resistance in wet and chemical environments
• 7 mm band width provides consistent clamping force across the hose bead
• 0.6 mm band thickness delivers strength while minimizing clamp footprint
• 10 mm inner ear width accommodates standard pincer-style crimping tools
• Single-ear stepless design creates a uniform 360-degree seal when crimped

Compatibility

Designed as an OEM-style replacement or new-installation ear clamp for hose and tubing assemblies requiring a 2.5-inch nominal stepless ear clamp.

Installation Notes

Installation requires a calibrated pincer or ear-clamp crimping tool sized for the ear width. Depressurize or drain the system and shut off fluid supply before installing or replacing any hose clamp. Ensure the hose is fully seated on the fitting barb before crimping. Once crimped, the ear clamp is a permanent, non-reusable fastener and must be cut off for removal.
