Hydraulic cylinders operate under continuous pressure, reciprocating motion, and demanding environmental conditions. In these systems, sealing performance directly affects efficiency, leakage control, maintenance intervals, and overall equipment reliability. Among the sealing solutions commonly used in hydraulic applications, PolyPak seals have gained broad adoption due to their ability to provide...
