Oetiker 10100004-100 2-ear Clamp 1/4 Inch

Product Description

The OETIKER 10100004-100 is a 2-ear clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from carbon steel with a zinc-plated head coating, this clamp provides reliable corrosion resistance in typical service environments. It features a 6.00 mm band width and 0.70 mm band thickness, with a clamping range of 5.00 mm to 7.00 mm, making it suitable for 1/4-inch nominal tubing. The 2-ear design deforms symmetrically when pinched, creating a uniform, leak-resistant seal. Licensed plumbers, HVAC technicians, and fluid-system installers commonly specify this style of ear clamp where reusable worm-drive clamps are not acceptable.

This clamp is sized for 1/4-inch nominal tubing and hose connections across residential and light commercial systems. Typical applications include refrigerant line insulation sleeves, low-pressure fluid lines, and small-diameter hose assemblies where a one-time, tamper-evident connection is required. The zinc-plated head coating suits installations in moderately humid indoor environments. Minimum order quantity is 10 pieces.

Key Features

• 2-ear clamp design creates a symmetrical, permanent crimp for leak-resistant hose retention
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• Clamping range of 5.00 mm to 7.00 mm suits 1/4-inch nominal tubing
• 6.00 mm band width and 0.70 mm band thickness provide consistent clamping force
• Inner ear width of 3.14 mm (0.1180 inches) for standard ear-clamp pincer tooling

Compatibility

Designed as an OEM-style replacement or service clamp for 1/4-inch nominal hose and tubing connections requiring a permanent 2-ear crimp fitting.

Installation Notes

Installation requires a dedicated ear-clamp pincer or clamp tool; do not substitute with pliers, as uneven force will prevent a proper seal. Shut off all fluid supply and relieve system pressure before removing or installing clamps. This is a one-time-use, non-reusable clamp — once pinched, it cannot be reopened and reused. Installation should conform to applicable system codes such as the IPC or IFGC depending on the service application.
