2U-5379: 127mm Inner Diameter Rod Seal

A Single-Acting Rod Seal is designed to seal in one direction only, usually in the outward direction. which consists of a basic sealing element made up of plastic and energizing O-Ring inside which is made up of rubber. When the hydraulic unit is pressurized, the piston moves outward and presses against the seal, which deforms and creates a seal between the rod and the cylinder wall. and it is resistant to hydraulic fluid and can withstand the pressures and temperatures of the hydraulic unit. Attributes: Provide flexibility and resistance to heat and wear. Provides effective sealing of the Hydraulic Cylinder. Applications: A Single-Acting Rod Seal is a type of hydraulic seal that is used to prevent fluid leakage between the piston rod and the cylinder in a hydraulic unit, mostly used in Cat® D250B, D25C, D25D, D300B, D300D, D30C, D30D, D35-HP, D350C, D350D, D350E, D35C, D400, D400D, D400E, D40D, D44, D44B, D550 and D550B Articulated Truck.
