An O-ring seal between pressure washer components forms a watertight seal
Pressure washers use rubber rings in the shape of the letter "O" that seal off connections between pipes, hoses, or fittings when they cross.
The seal's shape effectively prevents water seepage and secures pressure washer connections and gave rise to its name.
Why do you replace your O-ring seal?
The rubber material of the O-ring can degrade or become worn with exposure to high pressure, temperature fluctuations, chemical exposure, or general wear and tear.
When O-rings become damaged, they lose their elasticity and fail to create a proper seal, which results in leaks or reduced pressure in the pressure washer system.
Is it a genuine spare part?
This O-ring seal by Karcher is a genuine pressure washer replacement part. Your pressure washer can work as good-as-new when cleaning surfaces.

Good quality item, I got what I paid for
I bought two of these rubber rings in order to replace the original seals for my Kärcher 1.180-639.0 pressure washer. The water was leaking between the electrical motor assembly and the pressure pump body. Easy to replace, I solved my problem and now there is not a single drop. Also, I'd like to mention that I did my homework pretty well in terms of the parts availability and cost, and I must say that I got the best price here at ransomspares.co.uk. Thanks!

does this o-ring fit the detergent nozzle?
Hi Robert, I cannot confirm that this o-ring is the same as the one located with the detergent nozzle as there are quite a few seals located in this Karcher. Please forward across your model and TYP number from your appliance to our parts form so we can confirm the correct o-ring seal for you.
