Zurn QE812GX Adapter, Brass, Barbed X Cup, 1 1/4 Inch Pipe Size, 2 1/2 Inch Overall Length

Brass barbed expansion fittings are larger than the inside diameter of PEX pipe or tubing. A manual or power expansion tool expands the pipe and reinforcing ring allowing the fitting to be inserted into the pipe. The pipe and ring shrink down onto the fitting to form strong, leak-free connections. Brass, a bright gold color, is compatible with nylon, polyethylene, and polyurethane tubing and suitable for use in air, water, and oil applications.
