Oetiker 10500328-100 1-ear Clamp 11/16 Inch

Product Description

The OETIKER 10500328-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, automotive, and HVAC applications. Constructed from carbon steel with a zinc-plated head coating, this clamp delivers consistent clamping force without the risk of loosening over time. It features a 7 mm band width and 0.75 mm band thickness, with a clamping range of 15.10 mm to 17.00 mm, making it suited for 11/16 inch nominal connections. Licensed plumbers, HVAC technicians, and fluid system installers rely on this style of clamp for leak-free assemblies in demanding service environments.

This clamp is used on flexible hose and tubing connections in residential and light commercial systems, including coolant lines, pneumatic tubing, and low-pressure fluid transfer assemblies. The 1-ear design requires a dedicated pincer or clamp tool to close, producing a uniform, non-serrated band around the hose for a clean, professional finish. It is well suited for close-tolerance installations where standard worm-drive or spring clamps do not fit.

Key Features

• 1-ear stepless design provides uniform, permanent clamping without loosening
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7 mm band width and 0.75 mm band thickness for consistent clamping force
• Clamping range of 15.10 mm to 17.00 mm fits 11/16 inch nominal hose sizes
• Inner ear width of 6.00 mm (0.2360 inches) for standard pincer tool engagement

Compatibility

Designed as an OEM-style replacement or new-installation clamp for flexible hose and tubing with an 11/16 inch nominal outside diameter falling within the 15.10 mm to 17.00 mm clamping range.

Installation Notes

Installation requires an OETIKER-style ear clamp pincer tool to close the ear and set the clamp. Ensure the hose or tubing is fully seated on the barb fitting before applying the clamp. Depressurize and drain the system completely before removing or replacing any existing clamps. Do not attempt to re-open or re-use a closed 1-ear clamp, as the ear is designed for single-use permanent closure.
