Oetiker 16705086 Ear Clamp 2-5/8 Inches Stainless Steel

Product Description

The OETIKER 16705086 is a single-ear clamp designed for permanent, tamper-resistant hose and tubing connections. The ear clamp works by deforming a raised ear section when compressed with pincer pliers, creating a uniform 360-degree grip around the hose or fitting. With a nominal size of 2-5/8 inches, a 7 mm band width, and a 0.6 mm band thickness, this clamp provides consistent clamping force without the loosening risk associated with screw-type clamps. It is constructed from stainless steel for corrosion resistance in wet or chemically aggressive environments. HVAC, plumbing, and automotive hose technicians commonly specify ear clamps where a low-profile, vibration-resistant connection is required.

This clamp is suited for residential and light commercial applications involving coolant hoses, refrigerant tubing insulation sleeves, condensate drain lines, and similar flexible hose assemblies. The 2-5/8 inch nominal size fits standard hose and tubing connections at that diameter. The stainless steel construction makes it appropriate for outdoor, high-humidity, or corrosive service environments where carbon steel clamps would degrade. Installers working on hydronic systems, HVAC condensate lines, and plumbing supply connections commonly use this style of clamp where a non-adjustable, one-time installation is acceptable.

Key Features

• Single-ear design creates a permanent, uniform 360-degree clamp when closed with pincer pliers
• Nominal size of 2-5/8 inches suits standard hose connections at that diameter
• 7 mm band width distributes clamping force evenly across the hose surface
• 0.6 mm band thickness provides structural rigidity while minimizing bulk
• Stainless steel construction resists corrosion in wet, outdoor, and chemically aggressive environments
• Low-profile design fits in tight clearance areas where worm-drive clamps will not fit

Compatibility

Designed as an OEM-style replacement ear clamp for flexible hose and tubing connections requiring a 2-5/8 inch nominal clamp diameter in HVAC, plumbing, and related trade applications.

Installation Notes

Ear clamps are installed by HVAC technicians, plumbers, and pipefitters using dedicated ear clamp pincer pliers — standard pliers or side cutters are not acceptable substitutes and will damage the clamp or produce an inadequate seal. Shut off fluid flow and relieve system pressure before removing an existing clamp or installing a new one. The ear clamp is a single-use, non-adjustable fastener; once closed it cannot be reopened and reused. Confirm the hose or tubing is fully seated on the fitting before closing the clamp.
