When air delivery has dropped off, one of the symptoms isusually a leaking or defective valve. We recommendour 32249294 Valve/Head Rebuild Kit. Our IngersollRand equivalent repair kit contains all the necessary partsfor a valve rebuild. Upon reassembly, make certain the valves lay flat againstthe seating surface surrounding the port hole. Otherwise the valveswill leak air, resulting in carbonization and reduced compressoroutput. eIndustrialSolutions provides quality Ingersoll Rand equivalent partsthat meet or exceed the OEM specifications. Aftermarket parts aremore cost effective than brand name parts and can typically allowfor a reduction in you annual maintenance costs over the life ofthe compressor.
