Campbell Hausfeld TF410821 Valve Plate Assembly

Campbell Hausfeld TF410821 Valve Plate Assembly (also listed as TF007000AJ) is a replacement valve plate for Campbell Hausfeld TF-series air compressors. Installed in the pump head, it coordinates the intake and exhaust pathways by seating against the cylinder head to seal the compression chamber during each stroke. This assembly is designed to fit TF-series models and is identified by the TF410821 and TF007000AJ part numbers in Campbell Hausfeld repair diagrams. Replacing a worn valve plate helps restore valve timing and compression efficiency, especially when a unit exhibits reduced pressure or irregular cycling. As part of the TF-series head assembly, it is typically used alongside the cylinder head gasket and related O-rings to maintain proper sealing and reliable operation of the pump head.
