This product is a high-performance sealing and structural component manufactured using fluorosilicone (FVMQ) overmolding on SUS304 stainless steel.

It combines the mechanical strength of SUS304 stainless steel with the superior chemical resistance and flexibility of fluorosilicone rubber, making it suitable for demanding environments involving fuel, oil, chemicals, and extreme temperatures.

The overmolding process creates a strong mechanical and partial chemical bond between the fluorosilicone elastomer and the metal substrate, ensuring long-term sealing stability and structural reliability.
