Oetiker 16705475 Ear Clamp 2-3/4 in Stainless Steel

Product Description

The OETIKER 16705475 is a single-ear clamp designed for secure, permanent hose and tubing connections in plumbing, automotive, HVAC, and fluid-handling applications. Constructed from stainless steel, this ear clamp delivers corrosion resistance and long-term holding strength after a single crimping operation. The band measures 7.00 mm in width and 0.60 mm in thickness, with a nominal pipe size of 2-3/4 inches and an inner ear width of 10.00 mm. Licensed tradespeople and experienced technicians install these clamps where a reusable worm-drive or T-bolt clamp is not appropriate and a low-profile, tamper-resistant connection is required.

This clamp is suited for residential and light commercial installations involving flexible hose assemblies, coolant lines, drain lines, and similar piping where a crimp-style connection is the specified method. The 2-3/4 inch nominal size fits correspondingly sized hose and tubing ends. Installation requires a standard ear-clamp pincer or crimping tool to deform the ear and lock the clamp in place. Once crimped, the connection is permanent and vibration-resistant, making this clamp a common choice in both shop fabrication and field service environments.

Key Features

• Single-ear crimp design provides a permanent, low-profile hose connection
• Stainless steel construction resists corrosion in wet and chemically active environments
• 7.00 mm band width and 0.60 mm band thickness for consistent clamping force
• 10.00 mm inner ear width allows proper seating of crimping tool jaws
• 2-3/4 inch nominal size fits standard hose and tubing of that diameter

Compatibility

Designed as an OEM-style replacement or new-installation ear clamp for flexible hoses and tubing with a nominal outside diameter of 2-3/4 inches where single-ear crimp clamps are specified.

Installation Notes

Installation is performed using a dedicated ear-clamp pincer or crimping tool rated for the clamp size — do not attempt to close the ear with pliers or improvised tools, as uneven deformation can compromise the seal. Ensure the hose is fully seated on the fitting barb before positioning the clamp over the ear location. Once crimped, the connection is permanent and the clamp cannot be reused. Follow applicable plumbing or mechanical codes for the specific system being serviced.
