Rod Seals
The rod seal is crucial in a cylinder application. Rod seals are also subject to the most severe service conditions. Failure can result in fluid leakage into the immediate area as it jeopardizes both performance and safety.
The rod seal's key features include:
- Performing as a dynamic seal along its inner diameter, and static along the outer diameter
- How it is immediately impacted by changes to the rod surface and fluid temperature fluctuations
- It's often subjected to the system's highest pressure variations and spikes
- Given the the system's level pressure range and the fluid compatibility, High Performance Seals offers numerous different rod seal options
UNLOADED U-CUP
U-cups are popular because of their small gland space, as they seal both the inside and outside diameters.
More 
LOADED U-CUP
Loaded U-cups offer greater low pressure sealing on both inside and outside diameters.
More
PREMIUM LOADED U-CUP
Premium loaded U-cups have two integrated seals, providing more effective low pressure sealing.

SPRING ENERGIZED
These PTFE seals are for extreme conditions that are unsuitable for conventional elastomeric seals.
More
BUFFER
Buffer seals have channels that protect rod seals from pressure spikes by allowing fluid to flow around the seal.
