Oetiker 15100003-100 2-ear Clamp 1/4 Inch

Product Description

The OETIKER 15100003-100 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 0.50 mm wall thickness and a 6.00 mm band width, providing consistent clamping force around the full circumference of the connection point. The 2-ear design allows the clamp to be swaged with standard pincer tools, creating a tamper-resistant, leak-resistant seal. Licensed technicians and plumbers rely on this style of clamp where push-to-connect or worm-gear clamps are not appropriate for the application.

This clamp is suited for nominal 1/4 inch tubing and hose connections in residential and light commercial systems. Typical applications include PEX tubing fittings, refrigerant-rated flexible hose assemblies, and condensate or coolant lines. The clamping range of 5.00 mm to 7.00 mm accommodates standard tubing ODs at this nominal size. Installers working on hydronic systems, refrigeration lines, and similar piped assemblies will find this clamp compatible with a range of tubing materials including rubber, silicone, and PEX.

Key Features

• 2-ear stepless design delivers uniform, 360-degree clamping force when swaged
• Stainless steel construction resists corrosion in wet and outdoor environments
• 6.00 mm band width provides broad contact area to reduce hose deformation
• 0.50 mm wall thickness maintains dimensional consistency during swaging
• Clamping range of 5.00 mm to 7.00 mm suits standard 1/4 inch nominal tubing
• Inner ear width of 3.14 mm (0.1180 inches) for compatibility with standard pincer tooling

Compatibility

Designed as an OEM-style stepless ear clamp for 1/4 inch nominal hose and tubing connections requiring a permanent, swaged seal.

Installation Notes

Installation requires a dedicated ear-clamp pincer or swaging tool rated for this clamp size — do not attempt to close the ears with pliers or substitute tooling, as improper swaging will compromise the seal. De-energize or shut off the fluid system and relieve any residual pressure before fitting or removing clamps. This clamp is intended for single-use permanent installation and should not be re-opened and reused once swaged. Follow applicable plumbing and mechanical codes for the jurisdiction when specifying clamp type and material for potable water or refrigerant service.
