Oetiker 16704967-100 Ear Clamp 1-5/16 in Stainless

Product Description

The OETIKER 16704967-100 is a single-ear clamp designed for permanent, vibration-resistant hose and tubing connections. The ear deforms plastically when closed with a pincer tool, creating a uniform 360-degree clamping force that eliminates leak paths. With a nominal size of 1-5/16 inches, a 7.00 mm band width, and a 0.60 mm band thickness, this clamp suits applications where a low-profile, tamper-evident seal is required. It is installed by HVAC technicians, plumbers, and automotive or industrial service professionals working with flexible hose assemblies.

This ear clamp is suited for residential and light commercial applications involving coolant hoses, heater hoses, drain lines, condensate tubing, and similar flexible connections in the 1-5/16-inch nominal diameter range. Its stainless steel construction makes it appropriate for environments with moisture exposure or mild corrosives. The single-ear design keeps the installed profile compact where clearance around the fitting is limited.

Key Features

• Single-ear design creates a permanent, uniform clamp when closed with a standard pincer or ear-clamp tool
• 1-5/16-inch nominal size fits common hose and tubing diameters in HVAC, plumbing, and fluid-handling assemblies
• 7.00 mm band width distributes clamping load evenly across the hose surface
• 0.60 mm band thickness provides structural rigidity without adding excess bulk
• Stainless steel construction resists corrosion in wet or humid service environments

Compatibility

Designed as an OEM-style replacement or new-installation ear clamp for flexible hose and tubing connections with a nominal diameter of 1-5/16 inches across HVAC, plumbing, and fluid-handling applications.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool or side-cutter pliers rated for ear clamp closure — standard worm-gear clamp tools will not close the ear correctly. Position the clamp over the hose before seating the fitting, then close the ear in a single, even squeeze. Once the ear is fully closed, the connection is permanent and the clamp cannot be reopened or reused. Always follow applicable plumbing or mechanical codes for the specific system being serviced.
