Product Description
ASME b16.20 high temperature R series flange oval or octagonal metal pad ring
Sealing ring is a kind of parts used to prevent liquid or gas leakage. Sealing ring material selection on its sealing performance and service life is of great significance, because the performance of the material directly affects the performance of the sealing ring. Sealing ring is usually used for bearing sealing, can prevent grease fire, avoid frequent refueling, and the structure is simple, so it is widely used in bearings, commonly used types of O-ring, rubber sealing ring, hydraulic cylinder sealing.size | Outside diameter:20-300mm;Inside diameter :10-290mm |
