A parker piston U-cup seal, also known simply as a U-cup seal or U-ring, is a type of hydraulic seal designed to provide effective sealing for reciprocating or dynamic hydraulic and pneumatic applications. The seal gets its name from its distinctive U-shaped cross-section. Here we will explore about parker piston U-cup seal profiles –

D-Rings
Parker’s D-Rings provide a cost effective alternative to traditional sealing in radial seal applications. They can be used in static, reciprocating or oscillating applications in the most extreme environmental conditions.
Lip Seals
Parker’s lip seals offer a wide range of benefits for many applications and markets. Such as low load or low closure force as well as a self-energizing requirements.
Low Drag D-Rings
Parker’s Low Drag D-rings provide a cost effective alternative to traditional sealing in radial seal applications where low friction environments are critical. D-Rings can be used in static, reciprocating or oscillating applications.
Bonded Piston Seals
Parker’s Bonded Piston Seals lower total system costs, reduce weight and save space. The one-piece design eases assembly and promotes long service life. Our bonded seals easily incorporate check valves, metering orifices, spring retainers and more.
