Oetiker 15100020-100 2-ear Clamp 1-1/2 Inch

Product Description

The OETIKER 15100020-100 is a 2-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from stainless steel, this clamp features a 10 mm band width and 1 mm wall thickness, providing consistent radial clamping force when crimped with standard ear-clamp pliers or a pincer tool. The clamping range spans 35 mm to 40 mm, making it suited for 1-1/2 inch nominal tubing. HVAC technicians, plumbers, and fluid-system installers use 2-ear clamps where a low-profile, tamper-resistant connection is required and where worm-gear or T-bolt clamps are not appropriate.

This clamp is commonly used in residential and light commercial applications including PEX tubing connections, condensate drain lines, coolant hoses, and similar low-to-medium pressure fluid transfer lines. The 1-1/2 inch nominal size suits standard tubing in those ranges. It is sold individually and is suitable wherever a single, non-reusable crimp-style clamp connection is specified by the system design or installation standard.

Key Features

• 2-ear stepless design provides uniform 360-degree clamping force when crimped
• Stainless steel construction resists corrosion in wet or humid environments
• 10 mm band width distributes load across the hose or tubing surface
• 1 mm band thickness balances flexibility and holding strength
• Clamping range of 35 mm to 40 mm fits 1-1/2 inch nominal tubing
• Low-profile ear does not rotate or back off after installation

Compatibility

Designed as a standard 2-ear crimp clamp for 1-1/2 inch nominal hose and tubing connections in plumbing, HVAC condensate, and fluid-handling assemblies.

Installation Notes

Installation requires a calibrated ear-clamp pincer tool or crimping pliers sized for the 2-ear clamp profile. Shut off fluid flow and relieve system pressure before removing any existing clamp or fitting. Once crimped, a 2-ear clamp is permanent and cannot be re-opened or reused. Verify the clamping range matches the actual outside diameter of the tubing before installation.
