U-Cups are one of the most popular lip seals used today. Loaded U-Cups are primarily intended for dynamic reciprocating applications. They are an excellent seal in low pressure rod or piston applications. As the system pressure increases, the loading lip force also increases, automatically compensating for the higher pressure while maintaining a positive seal. A variety of profiles, materials, and sizes are available to suit specific requirements.
