Product Formation

The UL/FM Grooved Split Flange is a core component for grooved piping systems, bridging pipes, valves, or equipment with grooved ends. Made of ASTM A536 ductile iron (red epoxy-coated for corrosion resistance) and sealed by EPDM gaskets, it meets UL (safety) and FM (fire equipment) certifications—ensuring compatibility with North American and global fire/industrial norms. Its split design allows on-site installation without disassembling existing pipelines, making it a cost-effective choice for rapid project deployment.
