Loaded U-cups are a type of lip seal that are primarily intended for dynamic reciprocating applications. The loaded U-cup is an excellent seal in low pressure rod and 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 styles, materials and sizes are available to suit your special requirements.



The standard O-ring loaded U-cup profile is square in cross section and is suitable for both rod and piston applications. The standard design can be widely used to replace existing hydraulic packing and O-rings without changing gland design.

Application Dynamic reciprocating applications and low pressure piston & rod applications.
