Abstract
A coupling device comprises a male coupling member and a female coupling member, each having outwardly extending ends which carry male and female sealing elements, respectively, formed with mating, spherical-shaped surfaces which are effective to force solvent or coating material which may have collected thereon into passageways formed in each of such sealing elements or onto facing surfaces of the coupling members to substantially prevent contamination of new coating material flowing through the coupling device after a cleaning and/or color change operation has been performed.
