🔌 Function

The seal kit renews the O-rings, rod seals, wipers and internal sealing components that prevent hydraulic fluid loss and pressure bypass in the matching trim or steering cylinder.

Common signs of failure / service requirement:

• Hydraulic fluid leaks around the piston rod

• Cylinder pressure bypass causes trim or steering drift

• Wiper seal no longer excludes water and debris

• O-rings are flattened, swollen or hardened

• System requires repeated bleeding after fluid loss
