OBA needing repair

[mjeckell]

I have a wits end OBA kit and the check valve that enters the manifold block has failed causing it to leak from the pin hole once the compressor hits 150 psi. I have taken apart the check valve and the black rubber holding the spring on the cyclinder failed. Looking to replace that check valve with the same one or id I can get a new black seal that would work as well. The rubber inside has seperated no longer causing a seal.

For sure replace the O-ring first
Available at any auto parts store take the old one with you to match it up.
List Time I had one fail I just grabbed a kit with an assortment of sizes, really nice to have that on hand.
