PTFE Bonded EPDM gasket is produced with high-quality EPDM rubber and PTFE for maximum chemical and corrosion resistance. They are suitable for fiberglass, glass-lined, and steel full-face flanges. The gaskets have Low bolt torque with superior sealing, Dual, Concentric, Convex sealing rings;
They will eliminate cracked flanges, reducing installation costs, while maintaining high performance. It is ideal for plastic piping systems, as well as metal or plastic-lined metal systems. Standards: ASME (ANSI) B16.5, JIS 10K, DIN2501 PN10/PN16, SABS1123, BS4504 etc
