Product Desciption
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.
Silicone Lip seal is a self-sealing ring, it relies on the lip and close to the surface of the sealing coupling, obstructing the leakage channel to obtain the sealing effect. The working pressure of the lip seal is the sum of the pre-pressing force and the fluid pressure. When the pressure of the sealing medium is increased, the lip is distracted and more closely fit with the sealing surface, so that the sealing performance be enhanced further. In addition, the lip edge also has the scraping oil function which also enhance the sealing performance of the seal.
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
Lip seals are mainly used in reciprocating seals, and compare with extrusion seals, such as O-ring, the reciprocating seal makes lip seals better overall performance, and longer service life.
Xiamen Better Silicone Rubber Co.,ltd advantages for Silicone Lip Seals Production

| Description | Y-shaped seal(Lip Seal) | O-ring seal(Extrusion Seal) |
| Advantage | Seal section size is small, the installation groove can be designed as a monolithic groove; groove processing, seal installation easy,can be used as two-way seal (dual pressure) | Excellent seal performance; Low friction at low pressure; Automatically compensate after small amount of wear. |
| Disadvantage | Poor sealing performance; Easy to roll and twist, causing damage easily; The lower friction margin,the poorer sealing performance | One-way seal; Complex sealing structure,large size; Cause oil pressure between two seals; |
| Main Application | Small size slide valve; Piston and rod seals which allow a small amount leakage | Piston and rod seals which require high seal performance. |
