Brand: HPSI
HPSI
The P Polyseals are molded from abrasion-resistant 93A polyurethane and designed for reliable hydraulic sealing in dynamic applications. A four-lobed expander ring energizes the sealing lips, even at zero pressure, helping prevent leakage when the system is idle. Optional SKF® 93A high-temperature urethane and SKF® 95A premium urethane materials are available for demanding operating conditions.
The Standard profile features equal seal height and cross section, creating a square seal geometry. It utilizes the Type D sealing lip, making it the standard choice for general-purpose hydraulic sealing applications.
