Rock Metal offers a wide selection of sealing materials in silicon carbide, carbon graphite, tungsten carbide, ceramic, rubber and stainless steel, etc. View our variety of sealing types equipped to handle the vast majority of sealing solutions and available for nearly all applications.

Carbon graphite has the good property of good resistant-corrosion, high thermal conductivity and lower friction, good self-lubrication, the smaller expansion;applied to water, oil, acid,alkali, etc. They can be made into the seal faces, bearings, and so on. It is ideal to choose it as the frictional mating rings.

Carbon graphite is for pump, oven, conveyor, damper, petrochemical, and chemical processing applications, mechanical seal, bushing, self-aligning(flange, pillow, hanger)assemblies, sleeve & bearing, vanes, rotors, electrical contact and brushes.
