Parker Series RDH industrial grade roundline welded hydraulic cylinders provide value through proven reliability, efficient performance and the quality that you expect from every Parker Cylinder Division product line. Each Series RDH hydraulic cylinder incorporates design features that are superior in a 3,000 psi roundline welded cylinder. These features include standard composite wear rings both in the head and on the piston, energized bi-directional piston seal and hard chrome plated piston rods.

The Tri-Lip Rod Seal in combination with the Double-Service Wiperseal™ comprises a sealing system that delivers dry rod performance. The one-piece piston is piloted to the piston rod and sealed with an O-ring to eliminate oil bypass through the joint. Anti-extrusion design O-ring Body End Seals provide leak-free service. Magnetic piston for actuating Parker ALS switches through carbon steel cylinders and EPS or CLS sensors are available for stroke position sensing. Port mounted counterbalance valves add versatility by offering hose break protection, preventing loads from drifting and controlling overrunning loads.

Every Series RDH cylinder is individually tested before leaving our plant to assure proper performance and leak-free operation. All Parker cylinder products carry an eighteen-month warranty.
