Oetiker 15500065-100 1-ear Clamp 3-7/8 in Stainless

Product Description

The OETIKER 15500065-100 is a single-ear stepless clamp used to create secure, permanent connections on hose, tubing, and flexible line assemblies. The clamp closes by crimping the raised ear with a pincer tool, collapsing it uniformly around the hose for a leak-free, vibration-resistant seal. With a 3-7/8 inch nominal size, a 7 mm band width, and a 0.6 mm wall thickness in stainless steel, this clamp is well suited for applications where corrosion resistance and consistent clamping force are required. Plumbers, HVAC technicians, and automotive or industrial fluid system installers routinely use this clamp type in demanding environments.

This clamp fits hose assemblies with an outside diameter in the clamping range of 96.40 mm to 99.50 mm. It is commonly used in residential and commercial plumbing, radiant heating systems, coolant lines, and similar fluid-handling applications where a low-profile, non-reusable clamp is preferred over a worm-gear or T-bolt design. The stainless steel construction makes it appropriate for wet, humid, or mildly corrosive environments.

Key Features

• Single-ear stepless design creates a uniform 360-degree seal when crimped
• Stainless steel construction resists corrosion in wet and humid environments
• Clamping range of 96.40 mm to 99.50 mm accommodates standard large-diameter hose ends
• 7 mm band width and 0.6 mm thickness provide a low-profile, compact footprint
• Ear inner width of 10.00 mm (0.394 inches) compatible with standard OETIKER pincer tooling
• Non-reusable, tamper-evident closure ensures joint integrity over the service life

Compatibility

Designed as an OEM-style replacement or new-installation 1-ear stepless clamp for hose assemblies with an outside diameter between 96.40 mm and 99.50 mm across plumbing, HVAC, and fluid system applications.

Installation Notes

Installation requires a calibrated OETIKER pincer or ear-clamp crimping tool — do not attempt to close the ear with pliers, as uneven crimping will compromise the seal. De-pressurize and drain the line before cutting out an existing clamp or installing a new one. Follow applicable plumbing or mechanical codes such as the IPC or IFGC when used on potable water or gas-adjacent assemblies. This clamp is non-reusable and must be cut off and replaced if the joint is ever reopened.
