The Z-CAC-291-1 valve plate gasket is a DeVilbiss high-pressure replacement gasket used between the finned aluminum compressor head and valve plate assembly on compatible air compressor pumps. This gasket helps create an airtight seal at the pump head, reducing compressed air leakage and supporting proper CFM output.

This Z-CAC-291-1 DeVilbiss gasket is made from reinforced Graphoil graphite-based gasket material bonded to metal wire mesh foil. The reinforced construction is designed to help address over-compression and brittleness concerns associated with earlier non-wire-mesh gasket styles.
