Oetiker 10500356-100 1-ear Clamp 2-3/8 Inch Carbon Steel

Product Description

The OETIKER 10500356-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. The single-ear design is crimped with a pincer tool, collapsing the ear to create a uniform 360-degree seal around the hose. Band width measures 7 mm and wall thickness is 0.75 mm, providing a consistent clamping profile without gaps or pressure points. The carbon steel body carries a zinc-plated head coating for corrosion resistance in damp or wet service environments. This clamp is sized at a nominal 2-3/8 inches with a clamping range of 57.40 mm to 60.50 mm.

This clamp is suited for residential and light commercial installations where a tamper-evident, low-profile connection is required. Typical applications include PEX tubing, flexible coolant lines, radiant heating supply and return connections, and barbed fitting assemblies. HVAC technicians, plumbers, and pipefitters install this type of clamp when a hose clamp must stay flush with surrounding components or fit inside tight valve bodies and manifold assemblies. The 2-3/8 inch nominal size matches common medium-diameter hose and tubing used in hydronic and refrigerant line sets.

Key Features

• 1-ear stepless design creates a uniform 360-degree seal when crimped
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• Clamping range of 57.40 mm to 60.50 mm for a precise fit on 2-3/8 inch nominal hose
• 7 mm band width distributes clamping load evenly across the hose surface
• 0.75 mm wall thickness keeps the clamp profile low in confined spaces
• Ear inner width of 0.394 inches (10.00 mm) compatible with standard pincer crimping tools

Compatibility

Designed as an OEM-style replacement or new-installation clamp for medium-diameter hose and tubing requiring a permanent 1-ear stepless connection in plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation requires a dedicated ear-clamp pincer or stepless clamp tool rated for the ear width. Shut off fluid supply and depressurize the line before removing or installing any hose clamp. Confirm the hose or tubing is fully seated on the barb or fitting before crimping. Once crimped, the ear clamp is permanent and cannot be reused; replacement requires cutting the old clamp off.
