A low blow-by compressor has a piston with at least one first ring disposed at the top end thereof and at least one second ring disposed at the bottom end thereof. A port is formed in the cylinder such that the port is above the second rings when the piston is positioned at top dead center and the port is below the first rings when the piston is positioned at bottom dead center such that fluid which blows by the first rings tends to exit the cylinder through the port rather than to blow-by the second rings. Thus any fluid which blows by the first rings can either be exhausted or recycled through the compressor inlet. The compressor utilizes reed valves wherein a first valve plate is attached to the cylinder and a second valve plate is disposed in laminar juxtaposition to the first valve plate. A reed valve gasket assembly is disposed intermediate the first and second plates and an o-ring is disposed about the periphery of the valve reed gasket assembly to prevent fluid leakage therethrough. Thus, the low blow-by compressor may be utilized in environments where leakage of the compressed fluid is undesirable.
