1. Purchase an Oil Seal Kit

The first step is to get an oil seal kit that is a perfect match for the damaged one…

Some popular pressure washer pumps are the Dewalt 4200,

…Honda GX 390, Comet ZWD-K 4042, and so on.

Knowing the model of your pressure washer pump will allow you to purchase the appropriate oil seal kit.

Replace the oil seal kit, as well as the water seal kit.

Some oil seals are composed of rubber, making removal and installation simpler.

2. Replace any cracked or worn-out seals

Some of the most typical problems with washer pumps are worn or damaged seals.

A pressure washer is equipped with many seals that are spread throughout the pressure washer.

One of them might break or wear out at any moment. This results in the creation of a leak.

It is not just oil that leaks, but also water.

Broken seals are often caused by a pressure washer that has not been properly maintained.

The seal also shrinks and extends. This is mostly determined by how hot the weather is.

High humidity conditions may cause seals to compress and expand,

…resulting in leakage as the temperature rises.

3. Regularly inspect your seal

Timely and appropriate maintenance of your pressure washer pump…

…is required to minimize oil leaks or complete pump damage.

To prevent this, be sure to check your seals at least twice a year and,

…if necessary, replace worn-out ones.
