A paint pouch fitting (A) for a paint dispensing system comprising a piston (D) slidable within a housing (C). A passage (22) in the housing (C) includes an inlet (42) communicating with a paint pouch (B), and outlet (24). The passage (22) also includes a piercable membrane (44) positioned between the inlet (42) and outlet (24). The piston (D) includes a blade (60) for piercing the membrane (44). The positioning of the piston (D) within the passage (22) defines two working positions (Figs. 16 and 17) allowing for four operational modes of shipping, piercing, dispensing, and storing.
