Oetiker 10500350-100 1-ear Clamp 2 Inches

Product Description

The OETIKER 10500350-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from carbon steel with a zinc-plated head coating, it provides corrosion resistance in demanding environments. The clamp features a 7 mm band width and 0.75 mm band thickness, with a clamping range of 48.40 mm to 51.50 mm, making it suited for 2-inch nominal connections. Installation requires a pincer-style ear-clamp tool to deform the ear and lock the clamp in place without slippage or loosening over time.

This 1-ear clamp is used in residential and light commercial settings where a permanent, vibration-resistant hose connection is required. Common applications include PEX tubing, radiator hoses, coolant lines, and other fluid conveyance systems where standard worm-drive clamps are not suitable. The single-ear design delivers uniform 360-degree compression around the hose or fitting.

Key Features

• 1-ear stepless design provides consistent radial clamping force
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7 mm band width and 0.75 mm band thickness for reliable grip
• Clamping range of 48.40 mm to 51.50 mm fits 2-inch nominal tubing
• Permanent installation — requires ear-clamp pincer tool for closure
• Inner ear width of 10.00 mm (0.394 inches) for standard pincer jaw compatibility

Compatibility

Designed as an OEM-style 1-ear stepless clamp for 2-inch nominal hose and tubing connections in plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation is performed using a dedicated ear-clamp pincer tool rated for the ear width. Shut off fluid supply and relieve system pressure before servicing any hose connection. Once the ear is deformed, the clamp is permanent and must be cut off for removal. Follow applicable plumbing or mechanical codes for the jurisdiction, including IPC or IFGC requirements where relevant.
