Description

Your O-ring seal creates a watertight seal between pressure washer parts 

When pipes, hoses, or fittings cross, pressure washers use rubber rings in the form of the letter "O" to seal the connections.

The seal gets its name from the way it is shaped; it effectively stops water seepage and keeps pressure washer connections safe.

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.
