1″ GMI UNION CONICAL

The 1 inch gmi union conical mech is a three-piece galvanized malleable iron fitting designed to allow for the easy connection and disconnection of piping without the need to rotate the pipe. featuring a conical (tapered) metal-to-metal seat, this mechanical union provides a high-pressure seal without the need for a separate gasket, making it ideal for high-temperature or high-vibration fire protection environments.
Manufactured from high-tensile malleable iron, this union is engineered for frequent disassembly during maintenance or equipment replacement. the red protective finish is specifically designed for fire suppression systems, offering excellent corrosion resistance and visibility. with precision-machined internal threads and a robust nut for secure tightening, it is a reliable choice for 1-inch water, gas, and air lines in commercial and industrial piping networks.
