P12-0.81SQB
P Urethane U-Seal, 13/16 X 1-1/16 X 1/8, SQB Style
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 SQB profile shares the same square dimensions as the Standard profile but incorporates a Type B beveled sealing lip. The beveled lip provides improved oil film breaking for enhanced sealing performance while maintaining the Standard profile dimensions.
