Nitrile U-Cup Seals, also known as HRU Homogeneous U-Cups or block vee seals, are designed for reliable performance in low-pressure pneumatic and hydraulic systems. These compact, single-material seals offer a dependable upgrade or direct replacement for AS568 O-Rings, especially in rod and piston applications where space is limited and sealing performance is critical. Made from 70 durometer Nitrile (Buna-N), they resist oils, fuels, and hydraulic fluids while delivering consistent sealing under pressures up to 500 PSI. Ideal for industrial cylinders, automation systems, and maintenance operations, HRU U-Cups provide cost-effective, long-lasting performance trusted by OEMs and field techs alike.

Operating temperature: -40° to +212°F (-40° to +100°C)

HRU50-11.00-50 Homogeneous U-Seals

11" ID X 12" OD X 1/2" HT Homogenous U-cups (block vees) are a non-loaded, single material U-cup. The HRU seal is popular in low pressure applications where a low friction seal would be beneficial. The seal is most commonly used in pneumatic applications as a rod or piston seal. The design is suited for situations where space is limited or as an O-Ring replacement. The HRU seal is typically made from an 80 durometer Nitrile but...
