Piston Seals
Piston Seals for preventing internal leakage in hydraulic cylinders, designed for bidirectional sealing under high pressure conditions. Available in various materials and custom designs with OEM manufacturing support.
Product overview
Product details
Piston Seals are manufactured from materials such as PU, PTFE, NBR, and FKM to provide reliable sealing in hydraulic cylinders. They prevent internal fluid leakage between pressure chambers, maintaining system efficiency and pressure stability.
These seals are used in hydraulic cylinders for construction machinery, agricultural equipment, industrial hydraulic systems, and heavy-duty machinery, operating under dynamic reciprocating conditions.
