Oetiker 15100023-100 2-ear Clamp 3/8 Inch

Product Description

The OETIKER 15100023-100 is a 2-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from stainless steel with a band width of 7.00 mm and a thickness of 0.80 mm, this clamp delivers consistent clamping force when properly swaged. The 3/8 inch nominal size covers a clamping range of 8.00 mm to 11.00 mm, making it well suited for small-diameter flexible tubing and low-pressure hose assemblies. Installation requires a pincer or ear-clamp tool to close the ears uniformly. Licensed plumbers, HVAC technicians, and refrigeration mechanics routinely use this style of clamp where a tamper-resistant, vibration-resistant connection is required.

This clamp is commonly used in residential and light commercial plumbing systems, PEX tubing assemblies, radiant heating loops, and refrigerant or fluid line connections where a compact, low-profile clamp is needed. The 2-ear design is standard in applications that demand a clean, non-reusable mechanical seal. Its small footprint makes it practical in tight spaces where larger band clamps cannot seat properly.

Key Features

• 2-ear stepless design provides uniform radial clamping force when swaged
• Stainless steel construction resists corrosion in wet and humid environments
• Clamping range of 8.00 mm to 11.00 mm suits 3/8 inch nominal hose and tubing
• Band width of 7.00 mm and thickness of 0.80 mm for a low-profile, secure fit
• Non-reusable, tamper-evident connection once ears are closed

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 3/8 inch nominal flexible hose and tubing requiring a 2-ear stepless clamp connection.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool rated for 2-ear stepless clamps — do not substitute with standard hose-clamp pliers. Shut off fluid supply and depressurize the line before servicing any connection. Ensure the tubing is fully seated on the fitting barb before positioning and swaging the clamp. Follow applicable IPC or IFGC guidelines for the specific piping system being serviced.
