Oetiker 15300036-100 1-ear Clamp 7/8 Inch

Product Description

The OETIKER 15300036-100 is a 1-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 7/8 inch nominal size with a clamping range of 19.50 to 21.80 millimeters. The single-ear design allows a pincer tool to swage the ear down, creating a uniform 360-degree seal with no over-tightening risk. Band width measures 0.295 inches and band thickness is 0.039 inches. Licensed plumbers, HVAC technicians, and mechanical contractors install this clamp where a low-profile, tamper-resistant connection is required.

This clamp is suited for residential and light commercial installations involving PEX tubing, coolant hoses, heater hoses, and similar flexible conduit. The 1-ear configuration is a standard choice for press-fit and barbed fittings where a smooth outer profile is needed to clear tight spaces or insulation. It is commonly used during new construction and retrofit work across plumbing, hydronic heating, and HVAC refrigerant-line accessory assemblies.

Compatibility

Designed as an OEM-style replacement or new-installation clamp for flexible hose and tubing connections requiring a 7/8 inch nominal 1-ear stepless clamp.

Installation Notes

Installation requires a pincer-type ear-clamp tool rated for 1-ear stepless clamps. Shut off water supply or depressurize the relevant system before installing or replacing any clamp. Verify the hose or tubing is fully seated on the barbed fitting before swaging. Once the ear is crimped, the clamp is permanent and cannot be re-used.
