Grooved couplings from TPMC provide secure, leak-tight joints for fire protection and industrial piping systems. Produced from high-strength ductile iron with EPDM gaskets, our product line includes rigid, flexible, reducing, heavy-duty, quick-install, and HDPE transition couplings. Designed for rapid mechanical assembly using track-head bolts and nuts, they accommodate pipe deflection and vibration while maintaining reliable sealing and simplifying maintenance.
