ABSTRACT:
A head port sealing gasket (56) is disclosed for use in a barrel compressor (40) which has a head (42) fit within a barrel casing (44). The sealing gasket (56) has a curved outer surface (60) matching the curvature of the inner diameter of the barrel casing (44). An O-ring is fit within an O-ring groove (62) in the outer surface to sealingly engage the inner surface of the barrel casing. The sealing gasket (56) is received within a port (68) formed into the outer cylindrical surface of the head. A chamfer (92) on the end of the casing (44) allows the head and sealing gasket mounted thereon to be slid into the proper position within the barrel casing without damage to the O-ring.
