Ductile Iron Rigid Grooved Coupling For Fire Protection
Made to Awwa C606 and ISO6182, we support OEM on logo and coating, with a 10 year warranty. FOB pricing runs US $6-12 per piece.
Product Overview
Our rigid grooved couplings are the connector we ship out most for joining two grooved fire and water mains. We cast them in QT450 ductile iron with an EPDM gasket, DN50 to DN200, rated Pn16 at 16 bar (232 psi) to Awwa C606 and ISO6182. When a pipe crew tells us they want a rigid or a flexible joint, we supply the matching coupling and coat it in epoxy for outdoor yards.
