P25-1.75-50
P Urethane U-Seal, 1-3/4 X 2-1/4 X 1/2, Deep 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 Deep profile uses the same Type D sealing lip as the Standard profile but has a greater seal height than cross section, resulting in a rectangular geometry. This profile is designed for applications requiring a deeper seal configuration.
