Karcher Pressure Washer Piston9.002-028.0

This is a genuine replacement pressure washer piston. 

Helps drive the water through your pressure washer at high speed—giving you that strong, steady spray to blast away dirt, grime, and buildup. Works with the pump to create pressure, so your washer can clean patios, driveways, cars, and more with ease.

Over time, constant motion and water exposure can wear it down or cause performance issues like reduced pressure or odd noises. If your washer’s losing power or struggling to clean like it used to, change it with this part. 

This piston for your pressure washer is from Karcher.
