1,ring,gasket,bushing,rod,tube,sleeve pipe
2,ssic or RB-sic

(silicon carbide or sic mechanical seal gasket,bushing,ring,oil seal,pump seal, seal face)

The silicon carbide has the advantages of excellent corrosion resistance,high coefficient of heat conductivity,self-lubricity,small expansion.It can be widely used in the petroleum,chemical,machinery-building,cosmonautics and motors industries.The frictional factor of combination of silicon carbide and carbon graphite is the least,so it widely applied to high characteristics for the mechanical seals.
