Grooved pipe fittings connect to pipe for transporting oil, water, gas, and other liquids for chemical, waste incineration, and semiconductor industry applications. Fittings connect with grooved pipe to change direction, add outlets, reduce outlets, or cap piping systems. These full-flow fittings work with grooved pipe to settle into the grooves for a secure connection. Galvanized steel grooved fittings are thick-walled steel dipped in a protective zinc coating to resist rust, corrosion, and mineral buildup, and withstand wet conditions. Grooved zinc galvanized steel fittings come in a variety of sizes and shapes.
