Oetiker 10100034-100 2-ear Clamp 1 Inch Carbon Steel

Product Description

The OETIKER 10100034-100 is a 2-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from carbon steel with a zinc-plated head coating, it delivers corrosion resistance in demanding service environments. The clamp features a 10 mm band width and 1.5 mm band thickness, providing consistent radial clamping force when crimped with standard ear-clamp pincer tools. Licensed plumbers, HVAC technicians, and fluid-system installers use this style of clamp where a low-profile, vibration-resistant connection is required and re-usability is not a concern.

This 2-ear clamp is suited for residential and light commercial installations where hose barb fittings, PEX transitions, coolant lines, or flexible conduit connections require a permanent mechanical seal. The 22.50 mm to 27.00 mm clamping range accommodates nominal 1-inch hose or tubing outside diameters within that band. It is commonly installed on radiant heating loops, refrigerant-side flexible connections, and potable water distribution systems where stepless clamps are the specified fastening method.

Key Features

• 2-ear stepless design creates a uniform 360-degree crimp when closed with pincer tooling
• Carbon steel construction with zinc-plated head coating for corrosion protection
• 10 mm band width distributes clamping load across a wide contact area
• 1.5 mm band thickness provides structural rigidity without over-stressing the hose wall
• Clamping range of 22.50 mm to 27.00 mm suits nominal 1-inch hose outside diameters
• Low-profile ear geometry minimizes clearance requirements in tight installations

Compatibility

Designed as an OEM-style replacement or new-installation 2-ear stepless clamp for nominal 1-inch hose and tubing connections where a clamping range of 22.50 mm to 27.00 mm is required.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool sized for 2-ear stepless clamps. Shut off fluid flow and depressurize the line before installing or removing any clamp. Inspect the hose bead or barb fitting for damage before crimping, as a deformed barb will compromise the seal regardless of clamp torque. This is a single-use, non-adjustable clamp and must be cut off and replaced if the connection is disturbed.
