Oetiker 15500050-100 1-ear Clamp 3 Inches

Product Description

The OETIKER 15500050-100 is a 1-ear stepless clamp used to create a secure, permanent crimp connection on hose assemblies, tubing, and fittings. It is made from stainless steel with a band width of 7 mm and a material thickness of 0.6 mm. The clamping range runs from 73.90 mm to 77.00 mm, making it suited for connections with a nominal size of 3 inches. The inner ear width measures 10.00 mm (0.394 inches). This type of clamp is installed with a dedicated ear clamp pincer tool and is widely used in plumbing, HVAC, and fluid handling applications by licensed tradespeople and experienced installers.

This clamp fits standard 3-inch hose and tubing assemblies in residential and light commercial applications. Typical use cases include coolant lines, drain connections, flexible duct collars, and PEX-style fittings where a low-profile, single-use crimp clamp is specified. The stainless steel construction resists corrosion in wet or humid environments, making it appropriate for plumbing and HVAC installations where long-term reliability is required.

Installation Notes

Installation requires a dedicated 1-ear clamp pincer or stepless clamp tool — do not attempt to seat with pliers or improvised tools, as uneven crimping may compromise the seal. Shut off water supply or depressurize the system before installing on pressurized lines. Follow applicable IPC or IFGC guidelines for the specific connection type. Inspect the ear after crimping to confirm full closure and no cracking in the band material.
