Whether you're supplying OEMs or retrofitting fleets, our materials are ready for global deployment.

Metal Inlay Flange Rubber Gaskets Engineered for Reliability. Certified for Global Standards. Our metal inlay flange rubber gaskets combine the resilience of high-grade elastomers with the structural integrity of precision-engineered steel inserts—delivering unmatched sealing performance across demanding industrial environments. Key Features: • Vulcanized Metal Core: Centrally embedded steel (SS304, SS316 etc) ensures blow-out safety and dimensional stability under extreme pressure and temperature. • Elastomer Versatility: Available in EPDM, NBR, HNBR, FKM, and more—each tailored to resist steam, chemicals, hydrocarbons, and aggressive media. • Low Surface Pressure Sealing: Achieves tight seals even at reduced bolt torque, minimizing flange stress and installation complexity. • Wide Temperature Range: Operational reliability up to 200°C, ideal for pipelines, HVAC, chemical processing, and transit systems. • EPDM variants available with EN45545 HL3 fire safety rating for rail applications. Applications: • Rail & Transit (EN45545 HL3-compliant) • Oil & Gas, Petrochemical • Power Plants & Industrial Equipment • Drinking Water & Food-Grade Systems (material-specific)
