Oetiker 10100027-100 2-ear Clamp 3/4 Inch Carbon Steel

Product Description

The OETIKER 10100027-100 is a 2-ear stepless clamp designed for secure, permanent hose and tube connections in fluid and pneumatic systems. Manufactured from carbon steel with a zinc-plated finish for corrosion resistance, this clamp features a nominal size of 3/4 inch and a clamping range of 16.20 mm to 20.00 mm. The 8.50 mm band width and 1.20 mm wall thickness deliver consistent radial clamping force when installed with the proper ear-closing tool. This clamp is widely used by plumbers, HVAC technicians, and refrigeration technicians working with flexible hose assemblies where a low-profile, vibration-resistant connection is required.

The 10100027-100 is suited for residential and light commercial applications including potable water lines, hydronic heating hoses, pneumatic tubing, and coolant lines. Its stepless design eliminates stress points around the hose circumference, making it a preferred choice when leak-free performance is critical. The zinc-plated carbon steel construction is appropriate for indoor and protected-outdoor installations. This clamp is sold individually but requires a minimum order quantity of 10 units.

Compatibility

Designed as an OEM-style stepless ear clamp for 3/4 inch nominal flexible hose and tubing assemblies in plumbing, HVAC, and fluid-handling applications.

Installation Notes

Installation requires a dedicated ear-closing tool or pincer-style clamp tool designed for stepless 2-ear clamps. Shut off and depressurize the system before removing or installing any hose clamp. Ensure the hose is fully seated on the fitting before closing the ears. Once the ears are closed, the clamp cannot be reopened and must be cut off for removal.
