35 year replacement part
Compressor valve block was not sealing. This o-ring was enlarged after years of use and found this replacement on eReplacementParts.com. Back in service in just a few days.

Brought my Crafstman Air compressor 919167312 back to life!
I bought this o-ring along with the compression ring and the filter kit. We had the filter for a long time, but without the housing it kept falling out and we eventually lost it. The compressor started to sound bad and eventually didn't build up any compression. Took it apart and the compression ring was all bent and the piston had some serious play inside the cylinder. The cylinder was fine though. There were no nicks or grooves inside.

Hard to find parts
This was part of an overhaul kit for an older Craftsman compressor. Parts are hard to find, but eReplacements had them. All arrived on time and in good shape. Everything was the correct size and went together well. Great company; highly recommended.

I think what happen was. Over time. Two of the head bolts came loose. Causing two of them to break off. Which caused to of the o rings to break.
