What is a PU Cup Seal?
A PU Cup Seal is a type of hydraulic seal with a cup-like profile that is primarily used in hydraulic cylinders and fluid power systems to prevent fluid leakage and maintain system pressure. The “cup” shape enables it to seal in one direction, usually under high-pressure environments.
Manufactured using Polyurethane (PU), these seals are valued for their exceptional strength, abrasion resistance, and flexibility. PU Cup Seals offer excellent sealing capabilities in high-load, high-pressure, and high-speed applications, making them ideal for both static and dynamic sealing needs.
As a reliable PU Cup Seal Manufacturer in Kolkata, Suja Rubber & PU Product provides seals that conform to international standards and can also be customized for specific applications.

Agricultural Equipment such as sprayers, tractors, and harvesters
Automotive Systems – shock absorbers, braking systems
