Oetiker 10100045-100 2-ear Clamp 1-1/2 Inch

Product Description

The OETIKER 10100045-100 is a 2-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and general fluid-handling applications. The clamp is manufactured from carbon steel with a zinc-plated head coating for corrosion resistance. It features a 10 mm band width and 1.5 mm band thickness, providing consistent radial clamping force when crimped with the appropriate ear-closing tool. The clamping range spans 35 mm to 40 mm, making it suitable for 1-1/2 inch nominal hose and tubing assemblies. Licensed trades and mechanical contractors rely on this style of clamp where a tamper-evident, vibration-resistant connection is required.

This clamp is used in residential and light commercial installations where hose barb fittings are joined to flexible tubing or hose. Typical applications include PEX tubing connections, coolant hoses, drain lines, and low-pressure fluid transfer assemblies. The 2-ear design allows the clamp to be installed and crimped in tight spaces using standard ear-closing pliers or a dedicated pincer tool. It is well suited for any application requiring a clean, single-use permanent clamp rather than a reusable screw-style band clamp.

Key Features

• 2-ear stepless design delivers uniform 360-degree clamping when ears are closed
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• 10 mm band width and 1.5 mm thickness for consistent holding strength
• Clamping range of 35 mm to 40 mm suits 1-1/2 inch nominal hose and tubing
• Compatible with standard ear-closing pliers and pincer-style crimping tools
• Tamper-evident once crimped — not designed for removal and reuse

Compatibility

Designed as an OEM-style replacement and general-use clamp for 1-1/2 inch nominal hose and tubing assemblies across plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation requires a calibrated ear-closing tool or pincer pliers rated for 2-ear clamps — do not substitute with standard slip-joint pliers, as improper closure reduces clamping force. Depressurize and drain the line before fitting the clamp and making the hose connection. Once the ears are crimped, the clamp is permanent and must be cut off for disassembly. Follow applicable IPC or IFGC guidelines for the specific piping system being serviced.
