Oetiker BDKP79686 1-ear Clamp 1/2 Inch Zinc-plated 50-pack

Product Description

The OETIKER BDKP79686 is a 1-ear stepless clamp designed for secure, permanent hose and tubing connections in plumbing, HVAC, and fluid-handling applications. With a nominal size of 1/2 inch and a clamping range of 11.40 mm to 13.30 mm, this clamp delivers consistent radial compression when closed with pincer tooling. The zinc-plated head coating provides corrosion resistance in typical installation environments. The inner ear width measures 0.2360 inches. Sold in a package quantity of 50, this clamp is well-suited for high-volume installs where a uniform, tamper-resistant connection is required.

This 1-ear clamp is commonly used in residential and light commercial plumbing and hydronic systems, including PEX tubing connections, radiant heating supply and return lines, and similar low-pressure fluid circuits. Plumbers and HVAC technicians reach for this clamp type when a single-use, non-adjustable crimp connection is specified by design or code. The 50-count packaging supports service van stocking and new construction rough-in work where consistent quantities are needed per fixture or loop run.

Installation Notes

Installation requires a dedicated 1-ear pincer or ear-closing tool rated for this clamp series — do not substitute pliers or generic crimpers, as improper closure will compromise the seal. Depressurize and drain the line before servicing any existing connection. Follow applicable IPC or IFGC provisions for tubing material and joint type in your jurisdiction. Inspect the closed ear for full closure and no cracking before system pressurization.
