Oetiker 10500344-100 1-ear Clamp 1-1/2 Inch Carbon Steel

Product Description

The OETIKER 10500344-100 is a single-ear stepless clamp used to create secure, permanent connections on hose and tubing assemblies. The one-ear design is crimped with a pincer tool, collapsing the ear to lock the clamp at a fixed diameter. Made from carbon steel with a zinc-plated head coating, it resists corrosion in typical plumbing, automotive, and fluid-transfer environments. The clamp has a 7 mm band width and 0.75 mm wall thickness, providing a consistent sealing pressure around the hose bead. Plumbers, HVAC technicians, and fluid-system assemblers use this clamp where a vibration-resistant, tamper-evident connection is required.

This clamp suits residential and light commercial applications involving coolant hoses, PEX tubing, dishwasher drain lines, ice-maker supply lines, and similar small-diameter flexible hose connections. The nominal size of 1-1/2 inches corresponds to a clamping range of 35.00 mm to 38.10 mm, making it appropriate for hose assemblies that fall within that diameter band. It is installed with a standard Oetiker ear-clamp pincer or equivalent single-ear crimping tool.

Key Features

• Single-ear stepless design creates a permanent, vibration-resistant connection
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 7 mm band width distributes clamping load evenly around the hose
• 0.75 mm wall thickness provides consistent radial pressure
• Clamping range of 35.00 mm to 38.10 mm suits 1-1/2 inch nominal hose
• Ear inner width of 0.394 inches (10.00 mm) accepts standard pincer tooling

Compatibility

Designed as a stepless one-ear replacement clamp for 1-1/2 inch nominal hose and tubing assemblies with an outside diameter falling within 35.00 mm to 38.10 mm.

Installation Notes

Installation requires a dedicated single-ear pincer tool rated for the ear width. Depressurize and drain any fluid lines before removing the existing clamp. Position the clamp over the hose bead, align the ear away from any obstruction, and crimp until the ear collapses fully. Once crimped, the clamp is not reusable and must be cut off for removal.
