Rubber Plunger Seal Rubber Plunger Seal, also called Rubber Piston Seal, Rubber Rod Seal and Silicone Lip 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 PlungerSeal 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 Plunger Seal & Lip 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 Rubber Plunger 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 Plunger Seals materials molded 3. In-depth knowledge of silicone rubber Plunger 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 Plunger Seals, but also can make silicone rubber & plastic + liquid silicone rubber over-molding products. For Rubber Plunger Seal& Piston Rod purchasing, the following factors should be comprehensively considered: Piston Rod movement speed Piston Rod's starting friction Plunger Seal Working pressure Plunger Seal Working temperature Plunger Seal working medium viscosity Allowable tolerance for leakage Plunger Seal's groove size Plunger Seal's fit tolerance for Piston Rod Custom Plunger 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
