ABSTRACT:
A fluid dispensing gun that features a cap with first and second inlets to receive separate, metered flows of fluid. The cap has a first duct that to direct flow from the first inlet to a first outlet. A check valve receives flow from the second inlet. The duct and the check valve are arranged to bring fluid flow from the first inlet into contact with fluid flow from the second inlet. The cap may be a separate, disposable piece, so that the gun need not be purged after each use.
