Description

O-ring seal for a waterproof link between pressure washer components 

A circular rubber ring resembling the letter "O" forms a watertight bond between parts where pipes, hoses, or fittings intersect in pressure washers.

This seal earns its name from its shape, serving not only to shield pressure washer connections but also to prevent water seepage effectively.

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 and this 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 good-as-new in cleaning surfaces.
