Description
Seal repair kits and maintenance kits for waterjet intensifier pumps, cutting heads and valve blocks.
Seal kits are the fastest way to restore a leaking intensifier, water switch, check valve or on/off valve without replacing the whole assembly. Our SJ catalogue carries kit-level references grouped by the assembly they service, which makes it easier for you to identify the correct kit before quoting.

Replacement notes
A repair kit is defined by the assembly it belongs to, not by the seal material alone. Please confirm the assembly or machine model and the existing part number, and we will match the kit. If you are unsure which assembly your machine uses, send a photo of the removed part or the machine nameplate.
Custom and non-standard kits
If your seal kit is not listed, send the drawing, sample or dimensions and the machine model. We will tell you whether we can assemble or manufacture a matching kit.
To quote, send your machine brand and model, the assembly or existing part reference, the quantity required, and a photo if you have one.
