Description
Rebuild Kit includes piston/rod assembly, head gasket, filter, piston cup, cylinder sleeve, o-ring, valve flappers, valve keepers, and screws. For Thomas air compressor pump models 607, 627 (.44 Stroke).
If you have a sudden loss of performance, if air leaks out of the intake filter, or if the compressor just isn't performing like it should, order this kit. A loss of pressure or slow pressurization is usually caused by damaged compression rings or gaskets and/or damaged or sticking valves.
