HW-90X100X7-J2GPolyurethane snap-in wiper seal with double lips
Hydraulic wiper seals prevent contaminants from entering a cylinder assembly and hydraulic system. HW seals are polyurethane snap-in wiper seals. They have a double-lip design with an internal-facing wiper lip that regulates the lubrication film on the rod. Double-acting wipers improve the performance and extend the service life of rod sealing systems.
