Oetiker 10100049-100 2-ear Clamp 1-3/4 Inch

Product Description

The OETIKER 10100049-100 is a 2-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from carbon steel with a zinc-plated head coating, it delivers reliable corrosion resistance in demanding service environments. The clamp features a 10 mm band width and 1.5 mm band thickness, with a clamping range of 40.60 mm to 46.00 mm, making it well-suited for 1-3/4 inch nominal hose and tubing assemblies. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of clamp where a permanent, vibration-resistant connection is required.

This 2-ear clamp is used in residential and light commercial installations where secure hose termination is critical. Typical applications include radiant heating tubing connections, PEX fittings, coolant hose assemblies, and general fluid-system plumbing. The 2-ear design distributes clamping force evenly around the hose circumference, reducing the risk of leaks at the connection point. It is appropriate for use wherever a permanent crimp-style clamp is specified over a worm-gear or screw-type alternative.

Key Features

• 2-ear stepless design provides uniform circumferential clamping force
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 10 mm band width for stable, broad contact area on hose
• 1.5 mm band thickness for structural rigidity under pressure
• Clamping range of 40.60 mm to 46.00 mm suits 1-3/4 inch nominal hose
• Designed for permanent installation using standard ear clamp pincer tools

Compatibility

Designed as an OEM-style replacement or new-installation 2-ear clamp for 1-3/4 inch nominal hose and tubing connections in plumbing, HVAC, and fluid-handling assemblies.

Installation Notes

Installation requires a dedicated ear clamp pincer tool sized for 2-ear stepless clamps. Shut off fluid supply and depressurize the system before servicing any hose connection. Ensure the hose is fully seated on the fitting barb before crimping the ears. This clamp is intended for permanent installation and is not reusable once crimped.
