Description

How does a grooved oil seal function on a pressure washer?

A grooved oil seal  prevents leakage of oil or other fluids within the machine. It has a flexible rubber or elastomeric material with a grooved design that helps create a tight seal between rotating and stationary components of the pressure washer. 

This type of seal is commonly found in the pump, engine, or gear housing, where rotating shafts or components penetrate the housing. 

Why do you need to replace them?

These seals can wear out or become damaged with continuous use, exposure to high pressures, or contact with abrasive substances. When a grooved oil seal deteriorates, it loses its ability to create an effective seal, and lead to oil or fluid leaks. 

Such leaks can cause lubrication issues, reduce the efficiency of the pressure washer, and potentially lead to more severe damage to internal components. 

Is it a genuine spare part? 

This grooved oil seal is a genuine Karcher pressure washer product. Your pressure washer can work good-as-new in cleaning surfaces.

Perfect for karcher service

Karcher jet wash started leaking oil... after some research online, found it to be some rubber seals that need replacing. (These plus an o-ring - also bought from here). These came quickly, are better value than from Kaercher, and fitted perfectly. Machine works perfectly now. Be sure to use compressor oil to re-fill (available from a well known car parts chain beginning with "H"). Not 5 stars all round only because I've only used a couple of times since the service.
