Karcher Pressure Washer O Ring Seal6.363-115.0

O-ring seals create a watertight link between pressure washer parts 

Pressure washers use rubber rings in the shape of the letter "O" to seal the connections where pipes, hoses, or fittings cross.

The seal's name derives from the way it is fashioned; it effectively prevents water seepage and secures pressure washer connections.

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.
