Description
What is an O-ring seal in pressure washers?
An O-ring seal in pressure washers is a type of rubber ring designed to create a watertight seal between two components where pipes, hoses, or fittings connect. It is called an O-ring due to its circular shape with a cross-section resembling the letter "O."
The O-ring seal acts as a barrier against water seepage and maintains the integrity of the pressure washer's connections.
Why do you replace them?
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 and this results in leaks or reduced pressure in the pressure washer system.
Is it a genuine spare part?
This O-ring seal kit by Karcher is a genuine pressure washer replacement part. Your pressure washer can work good-as-new in cleaning surfaces.
Includes:
- 16 x O rings, 5 different sizes
- 4 x yellow safety plugs

Complete set
I got this just in case the problem with my jamming lance was not the handgun. The problem was resolved by replacing the handgun but it seemed like a good idea to replace the O rings too. All good.
Great find
I was concerned I would need to replace the entire jet hose on my Karcher K7. The O RING SEAL KIT was such a small ,simple, easy to fit part that solved the problem and there is a second one of the same size in the kit if needed.
GOOD PART
easy to fit and sorted out the problem with the lance being tight on the new k4 full control
Very usefull
Cured the leaking problems and also made product future proof
Ideal kit to cover most replaceable seals
A little pricy for what it is but that’s the price for convenience of a kit I suppose that aside not all seals required for my model but ones that were required were a perfect fit helping in part to clear my pulsating and low output pressure, machine as good as new again
Karcher o"ring seal kit
I have only used a couple of seals but it has done the job stopping the water leak, the other parts are for spares, so yes the kit is fine for my karcher.
