NBR/FKM/Viton/EPDM/HNBR/CR/ACM/FVMQ Rubber Seal

 Rubber Seal, Lip Seal,Oil 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 Hydraulic Seals.   Silicone Lip seal/oil 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.

Our products are applied in automobile,chemical,electrical industry and electronics,hydraulics and pneumatics,machine builders,petrol and allied industry,power industry, incl nuclear,off shore,solar,oil and gas etc.  

Oil Seals are used to prevent oil leakage from rotary shaft and housing clearance. It has a flexible lip that rubs against a shaft or housing to prevent leakage or ingress of fluid and dirt. Seal selection is based on shaft diameter, housing bore diameter and width, shaft speed, working temperature, fluid, pressure differential and service conditions. Common configurations include single lip, double lip, triple lip and four or more lips.   Rubber sealing element or lip material choices for oil seals include: Nitrile Rubber (NBR), Acrylic Rubber (ACM), Silicon Rubber (VMQ), Fluorocarbon Rubber (Viton/FKM), Ethylene Propylene Rubber (EPDM), Tetrafluoroethylene Resin (PTFE). To resist wear, the compound durometer (hardness) is typically 70 to 85 shores A.
