Oetiker 15500020-100 1-ear Clamp 1-5/16 in Stainless

Product Description

The OETIKER 15500020-100 is a single-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. The clamp features a clamping range of 30.00 mm to 33.10 mm, a band width of 7.00 mm, and a band thickness of 0.60 mm. Constructed from stainless steel, it resists corrosion in wet and high-humidity environments. The 1-ear design allows installation with standard ear-clamp pincer tools, creating a uniform 360-degree compression without over-tightening risk. Licensed plumbers, HVAC technicians, and pipefitters commonly specify this clamp for PEX, silicone hose, and corrugated tubing terminations.

This clamp is suited for residential and light commercial installations where a clean, low-profile crimp connection is required. Typical applications include PEX water supply lines, HVAC condensate and coolant hose fittings, and barbed fitting connections on flexible tubing. The nominal size of 1-5/16 inches makes it appropriate for tubing with an outer diameter that falls within the 30.00 mm to 33.10 mm clamping range. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Single-ear stepless design provides uniform radial compression around the hose or tubing
• Stainless steel construction resists corrosion in wet, humid, and outdoor environments
• Clamping range of 30.00 mm to 33.10 mm fits nominal 1-5/16 inch tubing
• Band width of 7.00 mm and thickness of 0.60 mm for a low-profile, secure fit
• Compatible with standard ear-clamp pincer tools for fast field installation

Compatibility

Designed as an OEM-style replacement or new-installation clamp for flexible hose and tubing connections with an outer diameter falling within the 30.00 mm to 33.10 mm clamping range, typical of nominal 1-5/16 inch fittings.

Installation Notes

Install with a calibrated ear-clamp pincer or pince-type crimping tool rated for stepless clamps. Ensure the tubing is fully seated on the barb fitting before crimping the ear. Power down or shut off fluid flow to the line before servicing any connection. Once crimped, the 1-ear clamp is a permanent fastener and cannot be reused after removal.
