Model #580752420 CRAFTSMAN power washer, gas

Question and Answers


I need to replace the o-ring of a pressure washer (580752420). The o-ring is on the pump. Do I need to put anything on the surface when I put it back together?


You don't need to put any oil or sealant on the o-ring to make it seal. Oil or sealant makes the o-ring slick and many times it will cause the o-ring to leak.
