A single piece gasket valve plate assembly for sealing and separating assembly parts secured to the valve plate of a reciprocating piston compressor. The gasket includes a compressible peripheral portion for sealing and separating the valve plate to the cylinder head. The device also includes compressible central portions, which are spaced from and integral with the peripheral portion, wherein the central portions members are adapted to encircle the suction ports of the valve plate to seal and separate the suction ports from the discharge ports. A connecting portion extending through the discharge chamber connects the peripheral portion of the gasket to the central portions.
