Metal covered gasket
Any sealing material such as flexible graphite, non-asbestos, and PTFE is coated in stainless steel, copper, carbon steel, and other metal materials. The filler material gives the gasket good resilience, and the coating prevents the gasket from being damaged by the erosion of the medium.
Nominal diameter: φ10～φ2000mm
It is mainly used for the sealing of flanges of pumps, valves, heat exchangers, etc. in the metallurgy, refining and chemical industries.
