IDU / ODU Piston Seal | Double-Acting Symmetrical Hydraulic Seal

The IDU and ODU Piston Seals are double-acting, symmetrical sealing elements designed for dynamic applications in hydraulic cylinders. These seals are ideal for pistons that require bidirectional sealing under high pressure and frequent stroke reversals.

Their lip geometry ensures equal sealing force on both sides of the piston, reducing wear and ensuring consistent performance. IDU/ODU profiles are especially suitable for compact groove designs and are compatible with most international cylinder standards.
