Drawing:
Optimized Sealing Design: The unique concentric convex ring design minimizes the required torque for a secure seal, unlike flat gaskets that demand higher bolt loads.
Patented Laminating Process: The PTFE is bonded to EPDM through a patented process, which enhances flexibility and reduces the required sealing torque, making it ideal for low-torque applications.
ANSI Full-Face Dimensions: This gasket meets ANSI full-face standards, ensuring compatibility with a wide range of piping systems.
Additional Safety:
The unique inner PTFE sealing ring ensures extra protection and sealing integrity for both gases and liquids.
Self-Centering & Easy Installation:
Built-in ring tab and self-centering design simplify alignment and installation, ensuring consistent sealing every time.
The PTFE EPDM Gasket is designed for full-face fiberglass, glass-lined, thermoplastic, and steel flanges. and it is ideal for piping systems where superior sealing and chemical resistance are critical
