Oetiker 15500011-100 1-ear Clamp 0.75 Inch

Product Description

The OETIKER 15500011-100 is a 1-ear stepless clamp designed to create a secure, permanent connection on hose and tubing assemblies. Manufactured from stainless steel, this clamp features a 0.75 inch nominal size with a band width of 7 mm and a band thickness of 0.6 mm. The single-ear design is cold-formed during installation, locking the clamp in place without threads or screws. Plumbers, HVAC technicians, and fluid-system assemblers rely on this style of clamp where vibration resistance and a low-profile seal are required.

This clamp is suited for residential and light commercial applications involving hose barb fittings, PEX tubing connections, coolant lines, and similar fluid or pneumatic assemblies. Its clamping range of 17 mm to 19.80 mm accommodates standard 0.75 inch nominal hose and tubing outside diameters. The stainless steel construction resists corrosion, making it appropriate for wet or outdoor environments where carbon steel hardware would degrade.

Key Features

• 1-ear stepless design creates a permanent, vibration-resistant connection
• Stainless steel construction for corrosion resistance in wet or exposed installations
• Clamping range of 17 mm to 19.80 mm suits standard 0.75 inch nominal hose OD
• Band width of 7 mm distributes clamping force evenly across the hose surface
• Band thickness of 0.6 mm provides consistent ear deformation during pinching
• Low-profile ear sits flush after installation, reducing interference in tight spaces

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 0.75 inch nominal hose and tubing assemblies requiring a stepless 1-ear style clamp within the 17 mm to 19.80 mm clamping range.

Installation Notes

Installation requires an OETIKER-style ear clamp pincer tool or equivalent single-ear clamp tool to cold-form the ear to its final locked position. Ensure the hose is fully seated on the barb fitting before positioning and closing the clamp. Power down or depressurize any system before servicing hose connections. Do not reuse a deformed clamp once the ear has been closed.
