Oetiker 16700035-100 Ear Clamp 1-1/8 in Stainless Steel

Product Description

The OETIKER 16700035-100 is a single-ear clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from stainless steel with a 7 mm band width and 0.6 mm wall thickness, this clamp delivers consistent clamping force when crimped with standard ear clamp pliers or a pincer tool. The single-ear design creates a vibration-resistant, leak-free connection that does not loosen over time. It suits nominal 1-1/8 inch diameter hose or tubing and is appropriate for both residential and light commercial work. Licensed tradespeople and experienced DIYers install this clamp wherever a reliable, one-time crimp connection is required.

This ear clamp is used across a broad range of trade applications including PEX tubing connections, coolant hose assemblies, refrigerant-side condensate drain connections, and low-pressure fluid lines. The stainless steel construction resists corrosion in wet or humid environments, making it suitable for exposed plumbing runs, mechanical rooms, and outdoor installations. It fits 1-1/8 inch nominal hose ends and is sized for applications where a smooth, low-profile clamp profile is preferred over worm-gear or spring clamp alternatives.

Key Features

• Single-ear crimp design provides permanent, vibration-resistant clamping force
• Stainless steel construction for corrosion resistance in wet and humid environments
• 7 mm band width distributes clamping load evenly across the hose surface
• 0.6 mm band thickness provides consistent deformation during crimping
• 10 mm inner ear width accommodates standard ear clamp pincer tooling
• Low-profile finished clamp minimizes clearance requirements in tight spaces

Compatibility

Designed as a standard OEM-style ear clamp for nominal 1-1/8 inch diameter hose and tubing connections across plumbing, HVAC, and fluid-handling applications.

Installation Notes

Installation requires dedicated ear clamp pliers or a ratcheting pincer tool rated for single-ear clamps. Shut off and depressurize the line before removing any existing clamp or hose. Slide the clamp onto the hose before seating the hose on the fitting barb, then position the ear over the center of the barb and crimp in a single, full squeeze. This is a permanent, non-reusable clamp and should not be opened or reused after crimping.
