Durlon® RCA®
National Hose & Accessory – Durlon® RCA® (Reduced Contact Area) Gaskets for Improved Sealing Performance
National Hose & Accessory supplies Durlon® RCA® (Reduced Contact Area) gaskets engineered with a serrated surface design that improves sealing under low bolt loads and on imperfect flange surfaces. This innovative pattern reduces the gasket’s contact area, minimizing friction during installation and optimizing seal integrity in torque-sensitive or limited-load applications.
Designed for chemical processing, steam, and general industrial systems, Durlon RCA® gaskets deliver reliable, consistent sealing performance even when flanges are worn or uneven. Their reduced-contact design enhances compression distribution, resulting in leak-free performance across varying pressures and thermal conditions.
With Houston-based inventory and responsive fabrication, National Hose & Accessory provides custom Durlon RCA® gaskets engineered for both new installations and maintenance operations.
