This listing is for a brand new powermate air compressor gasket kit, part number: E100959. This kit is compatible with Powermate air compressor model: VSF1080421, Industrial Air brand model: CP1080224, and also for Sears Craftsman air compressor, model: 921.153101 .
These are just some of the more common models this kit fits. We recommend if your gaskets look like this that you do some measuring to see if they might fit your compressor. The round gaskets measure 3-1/8" outside diameter with the bolt holes measuring 2-9/16" across center to center. The head gasket may measure a little bit larger in diameter just because its cut a little larger on the outside.
The square gasket is 2.5" across, and the crankcase oil seal rubber gasket measures about 4" wide and 3-3/4" tall.
This kit includes all gaskets shown in the picture: oil crankcase seal rubber gasket, square cylinder to crankcase gasket, and three round gaskets which are the cylinder to valve plate gasket, the center valve plate gasket and the valve plate to head gasket.
