Oetiker 10100019-100 2-ear Clamp 9/16 Inch

Product Description

The OETIKER 10100019-100 is a 2-ear stepless clamp designed for permanent, vibration-resistant hose and tubing connections. Manufactured from carbon steel with a zinc-plated head coating, this clamp provides reliable clamping force across a range of 12.50 mm to 15.00 mm. The band measures 7.50 mm wide and 1.00 mm thick, delivering a consistent seal when crimped with the appropriate pincer tool. This clamp is commonly installed by HVAC technicians, plumbers, and refrigeration mechanics who require a compact, tamper-resistant fastening method for flexible hose assemblies in tight spaces.

The 10100019-100 is suited for residential and light commercial applications where hose-to-barb connections must be secured without the risk of clamp loosening over time. Typical uses include refrigerant drain lines, hydronic tubing connections, automotive coolant hoses, and low-pressure fluid transfer assemblies. Its small profile makes it well suited for installations in confined areas where standard worm-gear clamps are impractical. The nominal size of 9/16 inch aligns with common small-diameter flexible tubing found across HVAC, plumbing, and fluid-handling systems.

Key Features

• Stepless 2-ear design provides uniform 360-degree clamping force when closed
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• Clamping range of 12.50 mm to 15.00 mm suits standard 9/16 inch hose fittings
• Band width of 7.50 mm and thickness of 1.00 mm for a low-profile, secure fit
• Compact ear geometry with inner ear width of 0.1580 inches (3.93 mm) for precise crimping

Compatibility

Designed as an OEM-style replacement or new-installation clamp for flexible hose and tubing connections requiring a 9/16 inch nominal clamp in residential and light commercial HVAC, plumbing, and fluid-handling systems.

Installation Notes

Installation requires a dedicated ear-clamp pincer or crimping tool rated for 2-ear stepless clamps — standard pliers will not produce a reliable closure. Depressurize and drain the line before installing or replacing any clamp on a pressurized fluid or refrigerant circuit. Once crimped, a 2-ear clamp is permanent and cannot be re-opened; plan routing and connections before closing. Follow applicable codes such as the International Plumbing Code or local mechanical codes when securing potable water or refrigerant-side drain connections.
