Abstract
An air fitting with an integral check valve includes a housing having an inlet and at least one outlet, a passage extending between the inlet and the at least one outlet with a valve seat being formed in the passage adjacent the at least one outlet with a portion between the outlet and the valve having a plurality of channels separated by lands which form a guide surface for the valve as it is being forced onto the valve seat by a spring. The channels allow passage of air around the valve member with less restriction when the valve member is lifted off the valve seat.
