The Homogenous U-cup 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. The HU seal is typically made from an 80 durometer Nitrile but also comes in Viton®/fluorocarbon, Neoprene and other homogenous materials.
As pressure is applied to the homogenous U-cup the seal experiences an increase in sealing force until it reaches the maximum pressure the seal can handle. Homogeneous U-cup seals can handle up to 500 PSI; however, if you have applications that require higher pressure capabilities please consult a Hi-Tech Seals’ sales representative.
