Rod Seals

Rod seals are the most important component in a cylinder application. Operating in the harshest service conditions, if the rod seal fails, fluids leak into the operation which endangers both performance and safety.

Crucial factors for any rod seal include:

  • It operates as a dynamic seal within its inner diameter, while it’s static along the outer diameter.
  • Changes in the rod surface and fluctuations in fluid temperature directly affect the rod seal.
  • It often experiences the greatest pressure variations, or spikes, in the system.

PSP offers numerous rod seal options, based on the system’s pressure level range and the fluid compatibility.

UNLOADED U-CUP

Unloaded U-Cup

U-cups seal both outside and inside diameters, and are also popular for the small gland space. More

LOADED U-CUP

Loaded U-Cup

Loaded U-cups offer greater low pressure sealing on both outside and inside diameters. More

PREMIUM LOADED U-CUP

Premium Loaded U-Cup

Two integrated seals allow premium loaded u-cups to provide greater low pressure sealing. More

SPRING ENERGIZED

Spring Energized

In extreme conditions where conventional elastomeric seals are unsuitable, rely on these PTFE seals. More

BUFFER

Buffer

Buffer seals allow fluid to flow around the seal to protect rod seals from pressure spikes. More
