Product Description

Pressure Seal Kit Specifications

It is a genuine OEM pressure seal kit which is designed for DeWALT pressure washers. The components are utilized to ensure tight seals between connected parts, preventing water from leaking past the high-pressure side of the piston. Over time seals will wear out and may begin to crack causing water leaks and eventually requiring replacements. The kit contains the necessary parts to maintain or repair your pump. Make sure to check the owner's manual repair guide and the diagrams of your model for the correct installation of the new components. Keep in mind this pressure seal kit is sold as an individual item. To perform this repair a wrench set and a screwdriver will be necessary to take apart and reassemble the pump.

Pressure washer came up to pressure ,squeeze trigger, total pressure loss
This is on a dewalt pressure washer with A 8.7 12 pump and Honda motor. Removed brass housing taking really good notes of how seals were placed Into housing
This pump is a triplex pump. Removed 3 brass Allen head plugs to expose the 3 checks and the other 3 checks are at the bottom of other 3 ports where the 3 pistons go in.
Used a needle nose plies to remove checks..Removed seals from piston ports. I used a Oring lubricant to assemble THE NEW SEALS THAT GO IN FIRST WERE VERY VERY HARD TO INSTALL HAD TO PUSH THEM IN THEN SLOWLY WORKED AROUND THE EDGE OF SEAL SLOWLY WORKING DOWN INTO BORE OF HOUSING
THE rest of parts install went easy Bolted unit up,pulled starter rope to rotate pump an motor ok so far
Hooked up water started motor and cleaned items I had out to do. Hope info helps
