Description

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

Pressure washers utilise O-ring seals to create watertight connections where pipes, hoses, or fittings intersect.

The name of these seals comes from their circular shape, resembling the letter "O." They prevent  water leakage and ensure secure connections in pressure washers.

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.

Are these genuine spare parts? 

These O-ring seals by Karcher are genuine pressure washer replacement parts. Your pressure washer can work as good-as-new when cleaning surfaces.

Karcher K2 O- Rings

Bought to stop leak on hose end connection to K2 pressure washer. No option to buy single O-ring so purchased this pack of 5. Does seem pricey for what they are but cheaper than buying a new pressure washer. Had no problem fitting the new O-ring.
