Oetiker 15500003-100 1-ear Clamp 0.5 Inch Stainless

Product Description

The OETIKER 15500003-100 is a 1-ear stepless clamp engineered for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. The clamp features a 0.5-inch nominal size with a clamping range of 11.40 mm to 13.30 mm, making it well-suited for small-diameter tubing work. Constructed from stainless steel with a band width of 7.00 mm and a band thickness of 0.60 mm, it provides corrosion resistance and consistent clamping force after pinching. Licensed plumbers, HVAC technicians, and mechanical contractors install this style of clamp where a low-profile, non-reusable connection is required.

This clamp is commonly used in residential and light commercial installations involving PEX tubing, barrier pipe, flexible hose, and similar small-bore connections. It is a standard fastener choice in radiant heating systems, potable water distribution, and refrigerant-line accessories where a smooth, uniform crimp is needed to meet pressure and leak-free performance requirements. The 1-ear design allows installation with a standard ear clamp pincer tool in confined spaces where conventional worm-drive clamps do not fit.

Key Features

• 1-ear stepless design delivers uniform, permanent clamping force around the hose circumference
• Stainless steel construction resists corrosion in wet and humid service environments
• 7.00 mm band width and 0.60 mm band thickness provide a low-profile, rigid connection
• Clamping range of 11.40 mm to 13.30 mm suits 0.5-inch nominal tubing and hose
• Compatible with standard ear clamp pincer tools for fast, single-action installation

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 0.5-inch nominal hose and tubing connections in plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician using a calibrated ear clamp pincer tool. Shut off the water supply or depressurize the system before fitting the clamp. Seat the clamp fully over the fitting before pinching to ensure the ear closes squarely and the band lies flat. Follow applicable IPC or IFGC requirements for connection type and pressure rating in the jurisdiction of installation.
