The silicon carbide has advanced property of wear-resistance, anti-corrosive, high heat conductivity & low dilatability and good intensity. This material is manufactured into seals rings of many types according to a specific need. Some of them are Type 1, Type 2, Type 21, Type 6, and Type 6A. They are differentiated by the materials used in their making, seat type, and shaft diameter.
We are capable to process the seal face according to your specific drawings.
