3-Series Spacer Tube 1-18395 Water Jet Pump Parts

The 3-Series Spacer Tube 1-18395 is an important structural alignment component used in 3-Series Waterjet Intensifier pump systems. Its main function is to maintain precise spacing between internal assemblies, ensuring correct alignment, balanced load distribution, and stable operation under ultra-high-pressure conditions.
This spacer tube is commonly installed between structural and mechanical components such as cylinders, seal housings, or support assemblies. It helps reduce direct mechanical stress, prevent component misalignment, and maintain the structural integrity of the intensifier system during continuous operation.
A high-quality spacer tube is essential for improving assembly stability, protecting critical components, and extending equipment service life.

Is 3-Series Spacer Tube 1-18395 a Wear Part?

Yes — the 3-Series Spacer Tube 1-18395 is considered a semi-wear part.
Although it does not directly contact high-pressure fluid, it continuously operates under mechanical stress, vibration, clamping force, and repeated maintenance cycles. Over time, it may experience wear, deformation, corrosion, or dimensional inaccuracy.
If not replaced when damaged, it can cause component misalignment, uneven stress distribution, accelerated wear, and reduced pump reliability.
Regular inspection during maintenance is strongly recommended.
