Oetiker 15500024-100 1-ear Clamp 1-1/2 in Stainless Steel

Product Description

The OETIKER 15500024-100 is a single-ear stepless clamp designed to create a permanent, vibration-resistant seal on hose and tubing connections. The clamp installs by pinching the raised ear with a standard ear-clamp tool, which deforms the ear and locks the clamp to a fixed diameter. It carries a nominal size of 1-1/2 inches, a band width of 7 mm, and a band thickness of 0.6 mm. The full stainless steel construction resists corrosion in wet, chemically active, or outdoor environments. Licensed plumbers, HVAC technicians, and automotive or industrial service techs are the primary installers for this style of clamp.

This clamp is suited for securing coolant hoses, heater hoses, fuel vapor lines, PEX tubing connections, and low-pressure fluid lines in both residential and light commercial applications. The clamping range of 35 mm to 38.10 mm makes it a direct fit for hose and tubing assemblies with an outside diameter in that range. The single-ear design provides a low-profile, tamper-resistant connection that cannot be loosened once set, which is preferred in production assembly and field repair situations where reliability over the service life of the assembly is critical.

Key Features

• Single-ear stepless design locks permanently when ear is crimped — cannot loosen under vibration or pressure cycling
• Clamping range of 35 mm to 38.10 mm suits standard 1-1/2 inch nominal hose and tubing
• Full stainless steel construction for corrosion resistance in wet and chemically active environments
• 7 mm band width distributes clamping force evenly across the hose bead
• 0.6 mm band thickness provides consistent crimp geometry with standard ear-clamp pincers
• Low-profile ear sits flush after installation, reducing snag and clearance concerns in tight assemblies

Compatibility

Designed for use with hose and tubing assemblies having an outside diameter between 35 mm and 38.10 mm in the 1-1/2 inch nominal size class. Verify hose outside diameter against the clamping range before installation.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool sized for the ear width — standard side-cutting pliers will not produce a consistent crimp. Depressurize and drain any fluid line before removing or installing clamps. Follow applicable plumbing or HVAC codes, including IPC and IFGC guidelines, for the specific system being serviced. Once crimped, the clamp is permanent and must be cut off for removal.
