Oetiker 10500327-100 1-ear Clamp 1 Inch Carbon Steel

Product Description

The OETIKER 10500327-100 is a 1-ear stepless clamp designed for permanent, vibration-resistant hose and tubing connections. The single-ear design is compressed with a pincer tool, collapsing the ear to create a 360-degree uniform seal around the hose. Made from carbon steel with a zinc-plated head coating, it provides corrosion resistance in typical plumbing, HVAC, and automotive fluid-line applications. The band is 7 mm wide and 0.75 mm thick, giving it the structural rigidity needed to maintain long-term clamping force without loosening over time. This clamp is installed by licensed plumbers, HVAC technicians, and mechanical contractors where a low-profile, tamper-evident connection is required.

This clamp suits residential and light commercial applications where hose barb fittings are used on flexible tubing, including hydronic heating lines, refrigerant condensate drain tubing, and fluid transfer assemblies. The 1-inch nominal size covers a clamping range of 22.80 mm to 25.60 mm, making it appropriate for standard 1-inch hose barb connections. Installers working on PEX, silicone, or rubber hose assemblies in tight spaces benefit from the low-profile ear geometry after compression.

Key Features

• Single-ear stepless design creates a uniform 360-degree seal when compressed
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• Clamping range of 22.80 mm to 25.60 mm for 1-inch nominal hose connections
• 7 mm band width and 0.75 mm band thickness for consistent clamping force
• Low-profile compressed profile suits confined installation spaces
• Tamper-evident single-use design confirms connection integrity on inspection

Compatibility

Designed as an OEM-style replacement or new-install clamp for 1-inch nominal hose barb fittings on flexible hose and tubing assemblies in plumbing, HVAC, and mechanical systems.

Installation Notes

Installation requires a dedicated ear-clamp pincer tool sized for single-ear clamps. Power down or depressurize the system and drain fluid from the line before fitting the clamp. Once compressed, the ear cannot be re-opened — inspect hose seating before crimping. Follow applicable IPC or IFGC guidelines for fluid-line connections in the system being serviced.
