ABSTRACT:
A recirculating paint supply system having a supply conduit, a return conduit and a push to connect fluid coupling assembly. The supply conduit supplies a liquid coating composition received from a supply to a spray nozzle. The return conduit returns the excess liquid coating composition supplied to the spray nozzle to the supply. The push to connect fluid coupling assembly receives an end portion of at least one of the supply conduit and the return conduit. The push to connect fluid coupling assembly includes a connector housing defining a bore having a first annular groove to retain an annular lock ring positioned within the groove. The lock ring is operable to grip and engage the outer periphery of the conduit to securably retain the conduit in the connector housing.
