Oetiker 10500338-100 1-ear Clamp 9/16 Inch

Product Description

The OETIKER 10500338-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, automotive, HVAC, and fluid-handling applications. Constructed from carbon steel with a zinc-plated head coating, this clamp delivers corrosion resistance and consistent clamping force when properly crimped. The band measures 7.00 mm wide and 0.75 mm thick, with a clamping range of 12.60 mm to 14.50 mm, making it suited for 9/16-inch nominal connections. Installation requires a standard ear-clamp pincer tool to cold-form the ear and lock the clamp in place without the need for hardware or screws. This clamp is a standard choice for licensed plumbers, HVAC technicians, and mechanical contractors working with flexible tubing assemblies.

This 1-ear clamp is typically used in residential and light commercial applications where a low-profile, vibration-resistant hose connection is required. Common installation scenarios include PEX tubing connections, coolant hose assemblies, condensate drain lines, and other fluid-transfer systems where a permanent, tamper-resistant clamp is preferred over a worm-gear or spring clamp. The 9/16-inch nominal size fits tubing in the corresponding diameter range without modification.

Key Features

• Carbon steel construction with zinc-plated head for corrosion resistance
• 7.00 mm band width provides broad clamping surface for even load distribution
• 0.75 mm band thickness for consistent cold-forming during crimping
• Clamping range of 12.60 mm to 14.50 mm suits 9/16-inch nominal tubing
• Single-ear stepless design creates a permanent, tamper-resistant seal
• Minimum order quantity of 10 units per order

Compatibility

Designed as an OEM-style replacement 1-ear stepless clamp for flexible hose and tubing assemblies requiring a 9/16-inch nominal clamp with a clamping range of 12.60 mm to 14.50 mm.

Installation Notes

Installation requires a dedicated ear-clamp pincer or pince-type crimping tool rated for single-ear clamps. Shut off fluid supply and depressurize the line before fitting the clamp over the hose and connection. Seat the clamp fully over the barb before crimping the ear to avoid an off-center seal. Do not reuse a crimped 1-ear clamp once formed.
