MPS Pu Rod & Piston Seal

MPS piston and rod seals are designed as U-cup seals for both hole and shaft applications. They are used as single-acting rod seals and hydraulic cylinder piston U cup seals.
They are molded from highly wear-resistant polyurethane (PU) and star-shaped NBR rings.
If you have special needs, we are here to provide custom seal solutions for you.
