Seal kit for P&H T350

The 938J254-2 seal kit contains a collection of components intended for the maintenance and repair of hydraulic outrigger cylinders. These seals are installed within the cylinder assembly to maintain fluid pressure and prevent hydraulic oil leakage during crane operation. By replacing the internal seals, the kit helps maintain the integrity of the outrigger system, which is necessary for the stability of the crane during lifting tasks.

This kit is compatible with the P&H T350 crane model. The components are sized to fit the specific dimensions of the outrigger cylinder housing, piston, and rod assembly found in this machine. Each seal is intended to function under the standard operating pressures and temperature ranges specified for the T350 hydraulic system.

Outrigger cylinders use a combination of piston seals, rod seals, and wipers to manage hydraulic fluid and exclude contaminants from the cylinder interior. Proper sealing ensures that the outrigger remains extended and locked in position under load. When these seals wear, they may allow fluid bypass or external leakage, which can affect the machine's ability to remain stable while deployed.
