China Custom Oil Resistant NBR Rubber Double Lip Seal

Rubber Lip Seal
Rubber Lip Seal, also called Rubber Piston Seal, Rubber Plunger Seal and Silicone 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.

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.

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 Rubber Lip Seals Production
1. Precision Own Mold-Making Technology since 1998, one stop service for silicone rubber compression molded components, plastic injection molded and liquid silicone rubber molding components.
2. In-depth knowledge of Rubber Lip Seals materials molded
3. In-depth knowledge of silicone rubber Lip Seals mold-making technology and Piston Seal molded technology.
Compression silicon rubber molded parts tolerance, can be +/- 0.02mm, like for medical device, smart cell phone, electronic and so on.
Our company not only can produce normal precision Rubber Lip Seals, but also can make silicone rubber & plastic + liquid silicone rubber over-molding products.

For Rubber Lip & Piston Rod purchasing, the following factors should be comprehensively considered:
Piston Rod movement speed
Piston Rod's starting friction
Lip Seal Working pressure
Lip Seal Working temperature
Lip Seal working medium viscosity
Allowable tolerance for leakage
Lip Seal's groove size
Lip Seal's fit tolerance for Piston Rod

Custom Lip Seals demands:
1.Offer 2D/3D design drawings or Samples
2.Hardness &Hardness tolerance Demands
3. Size tolerance
4. Materials Demands: Rubber, Silicone, NBR, etc
5. Quantity
