This is for 4 Hose to Gun orings for the AR200, AR300, and AR500 ARBlue series washers and are upgraded to EPDM rubber.  Not for the AR100 series.

The hose to gun oring is the most often torn, lost, or worn out seal on AR pressure washers.  There is only 1 of these orings in most replacement kits, so a new full 6 oring kit is needed just to get that single oring.  Unfortunately none of the seals are hardware store size.

If your AR washer leaks where the hose goes into the spray gun then you need this kit.

If you want the full oring kit I have a listing here


This kit is for 4 hose to gun orings (1/3 inch OD) and they’re upgraded to epdm rubber instead of regular nitrile.   EPDM has the same Duro 70 hardness as nitrile, with the same flexibility, but is less prone to ripping from wear.   Epdm or higher quality is what I ship for all of my hose reel or pressure washer seals.  This is the same size hose to gun oring that comes in the AR PW909104K kit.
