Oetiker 15100022-100 2-ear Clamp 1-3/4 Inch

Product Description

The OETIKER 15100022-100 is a 2-ear stepless clamp designed for permanent, vibration-resistant hose connections in plumbing, HVAC, automotive, and industrial fluid-handling applications. Manufactured from stainless steel with a 10 mm band width and 1 mm wall thickness, this clamp delivers consistent radial clamping force when crimped with the correct pincer tool. The 2-ear design allows the clamp to be installed and crimped in tight spaces where traditional worm-gear or screw clamps are impractical. Licensed HVAC technicians, plumbers, and mechanical contractors rely on this style of clamp for leak-free connections on flexible tubing and hose barb fittings.

This clamp is suited for residential and light commercial systems where flexible hose terminations require a secure, low-profile connection. Common applications include hydronic heating lines, refrigerant-side tubing insulation sleeves, condensate drain hose connections, and potable or non-potable plumbing distribution tubing. The nominal size of 1-3/4 inches corresponds to a clamping range of 40.60 mm to 46.00 mm, making it compatible with hoses and fittings that fall within that outside diameter window.

Key Features

• Stainless steel construction resists corrosion in wet or humid environments
• 10 mm band width provides uniform clamping pressure distribution
• 1 mm band thickness supports consistent crimp geometry
• 2-ear stepless design eliminates the overlap gap found in open-ear clamps
• Clamping range of 40.60 mm to 46.00 mm suits 1-3/4 inch nominal hose fittings
• Single-use crimp installation produces a tamper-evident, permanent seal

Compatibility

Designed as an OEM-style replacement or new-installation clamp for flexible hose and tubing connections with an outside diameter falling within the 40.60 mm to 46.00 mm clamping range.

Installation Notes

Installation requires a calibrated ear-clamp crimping tool; do not attempt to close 2-ear clamps with pliers or improvised tools, as uneven force will distort the ear geometry and compromise the seal. Depressurize and drain the system before installing or replacing any hose clamp. Ensure the hose is fully seated on the barb fitting before positioning the clamp over the bead. This type of clamp is intended for single use and should be cut off and replaced rather than re-used after removal.
