60K Backup Seal Sleeve 1-11365 Waterjet Parts Supplier

The 60K Spare Sealing Sleeve 1-11365 is a critical support component used in 60K high-pressure water jet Booster Pump systems. Its primary function is to provide structural support for the sealing elements, protect the main seals from deformation, and maintain stable sealing performance under ultra-high-pressure conditions.
This seal sleeve works in conjunction with the sealing elements, retaining rings, and high-pressure cylinder assemblies to prevent extrusion deformation of the sealing elements, reduce wear, and enhance the overall reliability of the sealing system.
A high-quality spare seal sleeve helps extend the service life of the sealing elements, reduce the risk of leakage, and ensure stable pump operation.
Is the 60K Spare Seal Sleeve 1-11365 considered a wear part?
Yes—the 60K Replacement Seal Sleeve 1-11365 is classified as a “semi-wear part.”
Although it is more durable than the sealing element and O-rings, it is continuously subjected to high pressure, friction, and mechanical loads. Over time, it may still experience wear, deformation, or surface damage, which directly affects sealing efficiency and the stability of the pump’s operation.
It is recommended to inspect it regularly during routine maintenance; if any signs of wear are detected, it should be replaced promptly.
