Oetiker 15500008-100 1-ear Clamp 5/8 Inch

Product Description

The OETIKER 15500008-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Constructed from stainless steel, this clamp features a 5/8 inch nominal size with a band width of 7 mm (0.276 inches) and a band thickness of 0.6 mm. The single-ear design allows the clamp to be swaged onto the fitting with a pincer tool, creating a leak-free, vibration-resistant seal without over-compression. Licensed plumbers, HVAC technicians, and pipefitters rely on this style of clamp for PEX, polyethylene, and barrier tubing connections where a permanent crimp is required.

This clamp is suited for residential and light commercial plumbing and HVAC systems where hose-to-barb or tubing-to-fitting connections must meet code requirements for permanence and pressure integrity. The 5/8 inch nominal size targets tubing with an outside diameter in the 13.50 mm to 15.70 mm clamping range, making it appropriate for common radiant heat, potable water, and refrigerant condensate drain line applications. Installers typically use this clamp in conjunction with OETIKER-compatible pincer or ear-closing tools.

Key Features

• 1-ear stepless design creates a permanent, tamper-evident seal when swaged
• Stainless steel construction resists corrosion in wet and outdoor environments
• Clamping range of 13.50 mm to 15.70 mm suits standard 5/8 inch OD tubing
• Band width of 7 mm (0.276 inches) distributes clamping force evenly across the tubing wall
• 0.6 mm band thickness provides consistent ear-closing performance with standard pincer tools

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 5/8 inch nominal hose and tubing connections in plumbing, HVAC, and fluid-transfer systems where a swaged 1-ear clamp is specified.

Installation Notes

Installation requires an OETIKER-compatible single-ear pincer or closing tool — do not attempt to close the ear with pliers or generic crimpers, as uneven force will compromise the seal. Shut off fluid supply and depressurize the line before removing or installing any clamp. Follow IPC or IFGC guidelines as applicable for the system type. Inspect the ear after closing to confirm full closure with no cracking at the fold.
