Oetiker 10500339-100 1-ear Clamp 5/8 Inch Carbon Steel

Product Description

The OETIKER 10500339-100 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. Manufactured from carbon steel with a zinc-plated head coating, this clamp delivers corrosion resistance and consistent clamping force. The band measures 7 mm (0.276 inches) wide and 0.75 mm thick, providing a clean, low-profile seal when crimped. It is sized for a nominal 5/8 inch fitting and accepts a clamping range of 13.50 mm to 15.70 mm. Licensed plumbers, HVAC technicians, and fluid system installers rely on 1-ear clamps like this one for leak-free terminations on PEX, silicone, and rubber hose assemblies.

This clamp is suited for residential and light commercial installations where a permanent, tamper-resistant connection is required. Common applications include PEX water supply lines, automotive coolant hose connections, radiant heating tubing, and other low-to-medium pressure fluid systems. The stepless ear design requires a dedicated pincer or ear-clamp tool to crimp, making it appropriate for professional installation environments where consistent closure force is critical to joint integrity.

Key Features

• 1-ear stepless design provides uniform 360-degree clamping pressure when crimped
• Carbon steel construction with zinc-plated head coating for corrosion resistance
• Band width of 7 mm (0.276 inches) and 0.75 mm thickness for a low-profile fit
• Clamping range of 13.50 mm to 15.70 mm suits standard 5/8 inch nominal fittings
• Permanent closure reduces risk of joint loosening over time compared to screw-type clamps

Compatibility

Designed as an OEM-style replacement or new-installation clamp for 5/8 inch nominal hose and tubing connections in residential and commercial plumbing, HVAC, and fluid-handling systems.

Installation Notes

Installation requires a calibrated ear-clamp pincer tool rated for stepless clamps — do not attempt to crimp with pliers or generic tools, as uneven force will compromise the seal. Shut off water supply or depressurize the fluid system before installing or replacing clamps on live lines. Follow applicable IPC or local plumbing code requirements for approved joining methods on the tubing type in use. Inspect the crimped ear after closure to confirm the ear is fully collapsed and the band seats flush against the fitting.
