Oetiker 15500038-100 1-ear Clamp 2-5/16 in Stainless Steel

Product Description

The OETIKER 15500038-100 is a single-ear stepless clamp designed for secure, permanent hose and tube connections in plumbing, HVAC, and fluid-handling applications. The clamp features a 7 mm band width and 0.6 mm wall thickness, constructed from stainless steel for corrosion resistance. It is installed by crimping the ear with an appropriate pincer tool, creating a uniform 360-degree compression seal around the hose or tubing. The clamping range runs from 55.9 mm to 59.0 mm in diameter, making it suited for 2-5/16 inch nominal hose connections. Licensed plumbers, HVAC technicians, and pipefitters install this type of clamp in residential and light commercial systems.

This clamp is used on flexible hose assemblies, push-fit tubing, PEX connections, radiant heating supply lines, and similar applications where a low-profile, tamper-resistant crimp connection is required. The one-ear design keeps installation fast and the finished connection compact, which is useful in tight mechanical spaces. It is a common choice for manifold connections, appliance supply lines, and hydronic heating loop fittings where worm-gear or T-bolt clamps are not appropriate.

Key Features

• Single-ear stepless design provides uniform 360-degree hose compression when crimped
• Stainless steel construction resists corrosion in wet and humid environments
• 7 mm band width with 0.6 mm wall thickness for consistent clamping force
• Clamping range of 55.9 mm to 59.0 mm suits 2-5/16 inch nominal hose OD
• Low-profile ear keeps installation clearance requirements minimal
• Permanent crimp connection reduces risk of loosening from vibration or pressure cycling

Compatibility

Designed as an OEM-style replacement or new-installation clamp for flexible hoses and tubing with an outside diameter in the 55.9 mm to 59.0 mm clamping range across residential and light commercial plumbing, HVAC, and hydronic systems.

Installation Notes

Installation requires a dedicated single-ear pincer or stepless clamp tool sized for this ear profile — standard worm-gear drivers cannot crimp this clamp type. Shut off water supply or depressurize the fluid circuit before assembling the hose connection. Verify hose OD falls within the 55.9 mm to 59.0 mm clamping range before selecting this clamp. Inspect the crimped ear after installation to confirm the ear is fully closed and the clamp sits square on the hose barb.
