H25-1.50SQB
H O-Ring Loaded Urethane U-Seal, 1-1/2 X 2 X 1/4, SQB Style
Brand: HPSI
HPSI
The H O-Ring Loaded U-Seal is molded from tough, abrasion-resistant polyurethane for reliable hydraulic sealing in dynamic applications. An integrated O-ring expander maintains consistent sealing force across the operating pressure range while enhancing low-pressure sealing performance to help prevent leakage.
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.
