Description

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.

Factors you watch out for when replacing 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.

does this fit the inlet elbow for kb9010
By j - york - 08/07/2019
Hi J Muir, I can confirm that this O Ring Seal is not for the water inlet elbow. The seal for the inlet elbow comes complete with the whole part which can be found through part RS512925 for your model of Karcher.
