My mid 90’s pro gold 830 series started leaking hydraulic oil. This solved the problem and I hope to get another 20 years out of it.

Looked good, fit. But it didn’t create any pressure. Don’t know why. Its really only supposed to be put on once because the metal presses into it to make the seal. After a couple of hours, I gave up and borrowed a sprayer from a friend and tossed mine. I will say that the sprayer painted many houses before tossing-just not the last one I needed to paint :).
