Oetiker 15300016-100 1-ear Clamp 7/16 in Stainless

Product Description

The OETIKER 15300016-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Formed from stainless steel, this clamp cinches down with a pincer tool to create a leak-free seal that cannot back off over time. The nominal size is 7/16 inch, with a clamping range of 9.60 to 11.30 millimeters. Band width measures 0.236 inches and wall thickness is 0.028 inches. Licensed plumbers, HVAC technicians, and fluid-systems installers rely on this style of clamp where vibration resistance and long service life are required.

This clamp suits residential and light commercial installations where PEX, rubber, silicone, or other flexible tubing must be terminated at barbed fittings. Common applications include potable water supply lines, radiant heating loops, refrigerant drain connections, and automotive or industrial fluid lines requiring a tamper-evident, single-use closure. The 1-ear design is standard for installations demanding a low-profile, consistent clamping force around the tubing circumference.

Key Features

• 1-ear stepless design provides uniform radial clamping force with no gap or back-off
• Stainless steel construction resists corrosion in wet and humid environments
• Clamping range of 9.60 to 11.30 millimeters suits 7/16 inch nominal tubing
• Band width of 0.236 inches and thickness of 0.028 inches for a compact, low-profile footprint
• Permanent closure style prevents loosening from vibration or thermal cycling

Compatibility

Designed as an OEM-style replacement or new-installation clamp for barbed fittings on flexible hose and tubing with an outside diameter falling within the 9.60 to 11.30 millimeter clamping range.

Installation Notes

Installation requires a dedicated ear-clamp pincer or stepless-clamp tool to properly close the ear without distortion. Shut off all system pressure and drain the line before fitting any clamp. Once closed, the 1-ear clamp is a permanent, single-use fastener and must be cut off and replaced if the connection is disturbed. Follow applicable plumbing or mechanical codes, such as the IPC or IFGC, for approved fitting and tubing types in the intended service.
