1. Product Advantages
Forever Seals’ FKM Flat Gasket delivers superior static sealing performance: excellent high-temperature resistance to maintain stable elasticity in long-term high-temperature working conditions; outstanding oil and chemical compatibility, suitable for mineral oil, synthetic oil, and various hydraulic media; low compression set to ensure long-term sealing without relaxation; high dimensional accuracy for easy installation and perfect fitting; strong anti-aging and anti-ozone performance for extended service life; and reliable pressure resistance for stable, leak-free sealing.2.Working Principle
The FKM Flat Gasket is installed in a standard closed groove. Under assembly compression, it produces stable elastic resilience to form an effective initial seal. When the system is under pressure, the gasket is further compressed and fits tightly against mating surfaces to block fluid leakage. The excellent heat, oil, and chemical resistance of FKM85 prevent material aging, swelling, or cracking, maintaining continuous sealing force even under long-term pressure and temperature changes.
