U-CUP Piston Rod Seals Lip Seals
U CUP Piston Rod Seals Lip Seals
Description:U-cups are a lip seal, named for the cross-section’s distinctive “U” shape. They are used for both dynamic and static appliC-A-Tions. The “U” shape energizes the sealing lips as the appliC-A-Tion pressure increases. This brilliant design has been modified to create several unique configurations. These modifiC-A-Tions provide additional benefits for a variety of appliC-A-Tions. The U-cups designs listed below are Hi-Tech Seals’ most common designs.

Installation
Some seal types are easily installed, while others are more difficult. Installation methods vary depending on a seal’s profile, size, material, and the appliC-A-Tion where it is being installed. Certain design factors need to be taken into consideration, as to protect the seal during installation.
Seal Life Expectancy
A seal’s life expectancy varies depending on seal type and material. Its performance depends on several factors including duty cycle, stroke, speed, pressure, surface finish, and fluid type. Each material is assigned a specific PV (pressure/velocity) values to create a theoretical guideline. In general, products that last longer will have a greater cost.
