Oetiker 10100011-100 2-ear Clamp 3/8 Inch Carbon Steel

Product Description

The OETIKER 10100011-100 is a 2-ear stepless clamp designed for permanent, secure connections on hose and tubing assemblies. The clamp closes by deforming two raised ears when crimped with the correct pincer tool, locking the hose onto the fitting without the risk of loosening over time. Built from carbon steel with a zinc-plated head coating for corrosion resistance, this clamp has a 7.00 mm band width and 1.00 mm band thickness. It is used in plumbing, HVAC, automotive, and fluid-handling applications where a low-profile, tamper-resistant clamp is required. The clamping range spans 8.10 mm to 11.00 mm, making it suited for 3/8-inch nominal tubing connections.

This clamp is a standard choice for connecting rubber or flexible tubing to barbed fittings in residential and light commercial systems. Typical applications include PEX tubing connections, coolant hose assemblies, low-pressure pneumatic lines, and similar soft-tubing terminations. The zinc-plated finish provides a base level of corrosion protection for general indoor and controlled-environment installations. This item is sold individually but carries a minimum order quantity of 100 pieces, making it appropriate for contractors and shops purchasing in volume for ongoing service work.

Key Features

• 2-ear stepless design creates a permanent, vibration-resistant seal when crimped
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7.00 mm band width and 1.00 mm band thickness for consistent clamping force
• Clamping range of 8.10 mm to 11.00 mm suits 3/8-inch nominal hose and tubing
• Low-profile ear geometry minimizes interference in tight installations
• UNSPSC Code 31162901 for procurement and cataloging compatibility

Compatibility

Designed as an OEM-style replacement or standard-use 2-ear clamp for 3/8-inch nominal hose and flexible tubing connections in plumbing, HVAC, and fluid-handling assemblies.

Installation Notes

Installation requires a dedicated ear-clamp pincer or stepless clamp tool sized for this clamp profile — do not attempt to close the ears with pliers or generic tools, as uneven crimping can compromise the seal. Ensure the hose is fully seated on the barbed fitting before positioning the clamp over the ears. Technicians should follow applicable codes such as IPC or IFGC when used in plumbing or gas-adjacent tubing applications. Inspect the crimped ears after installation to confirm both ears are fully collapsed and the band sits flush against the hose surface.
