O-rings are flexible circles which are used to prevent leaks and maintain pressure. This part is an authentic OEM replacement ring used in Karcher pressure washers. These O-rings are used at the connection point between the machine and its hose. This set includes five (5) identical O-rings.
Please note that the wand itself uses a separate set of O-rings, part # 2.640-729.0 O-Ring Seal Set. Multiple other sizes of O-ring are used in various other spots on these machines; see manual for part numbers and placements.

This was on a Karcher Pressure Washer and it has no model number. Going by the diagrams, I selected what I thought was the proper part, but the size was wrong. eReplacements shipped the proper part number, but I was unable to select the proper number due to not knowing the model number. Finally found one at a big box store.
Shipment was very fast, issue was my fault (or really Karcher's for making selection of model parts almost impossible).

Had rebuilt a Karcher pressure washer a year or two ago, so I knew eRlacementParts.com had these O-Rings in stock. It was easier to order them online than waste time looking through parts bins at hardware store, and I got OEM parts rather than generic, which may not have been exactly correct.

Nice! No leaks.
I will, however, from now on wet the ring (a little saliva would work) before inserting it to minimize the chance of tearing the new one.
Output hose would not hold pressure and stay attached to washer.
