Silicone Rubber Plunger Seal Plunger Seal, Lip Seal, also called Piston Seal, Radial Seal & Rod Seal, consists of outside diameter lip and inside diameter lip, which is used for fluid seals and specifically designed as piston seals to work in pneumatic and hydraulic cylinder applications, also known as Rubber Pneumatic seals and Rubber ydraulic Seals. Rubber Lip Seal is made of high grade silicone, liquid silicone rubber(LSR), NBR, FKM, PU Rubber, etc, which mainly produced by Silicone Rubber Compression Mold tooling or LSR injection Molding (LIM) with middle mold plates.
Rubber Lip Seal & Rod Seals application environment and working speed ranges:
Working pressure: < 25 MPa
Working temperature: -40~+120ºC
Medium: hydraulic oil, water, air
NBR: 0.01~0.6 m/s
FKM: 0.05~0.3 m/s
PU rubber: 0.01~1 m/s Our advantages for Plunger Seals Production
