A family of O-ring loaded U-cups developed by combining materials and sealing force control.
Primarily designed to keep rods and cylinders free from foreign matter. Some types offer sealing functions as well.
"U" shaped seals are self-sealing both on the inside and outside. Efficient in low speed, low pressure applications.
Economical, long lasting and ubiquitous, piston cups are used on piston heads and rams. Direct fit with sealing at the edge.
Natural materials provide benefits nitrile seals cannot match, including a unique combination of strength, pliability and resilience.
