A rigid thermoplastic manifold for the distribution of pressurized carbonated water has an elongate tubular thermoplastic body with a plurality of apertures spaced along its length, a plurality of identical thermoplastic outlet fittings which each have at inlet spud with a sonic energy director and a pair of arcuate sonic energy directors spaced one on each side from the spud, each outlet fitting being fastened and sealed to the tube with three discrete sonic welds. A method of making the manifold is also provided.

A thermoplastic carbonated water distribution manifold for fluidly connecting a plurality of post-mix carbonated beverage dispensing valves to a singular source of carbonated water, comprising: (a) an elongate thermoplastic tube having an elongate internal carbonated water plenum; (b) inlet means secured to said tube for introducing carbonated water into the plenum; (c) plugs closing the ends of the plenum; (d) a plurality of radial apertures through the tube and into the plenum, said apertures being spaced from each other and being in a line along the length of the tube, said apertures having their axis in a common flat plane; (e) a plurality of discrete elongate tubular thermoplastic water outlet fittings having their axis in said plane, each outlet fitting having means on one end for direct connection to the water inlet of a beverage dispensing valve, and a spud on the second and opposite end, each spud being in a respective aperture; and (f) a sonic welding energy director on a diametric periphery of each spud, each energy director being sonically fused into the thermoplastic tube within the respective aperture. A method of making a thermoplastic carbonated water distribution manifold comprising the steps of (a) cutting an elongate extruded and rigid thermoplastic tube to a predetermined length; (b) making a plurality of discrete and spaced apart apertures along the length of the tube and through said tube from outside to inside, said apertures having axis in a common single flat plane; (c) providing a like plurality of rigid thermoplastic outlet fittings, each fitting having a tubular outlet end sealably connectible to the water inlet of a post-mix beverage dispensing valve and an inlet spud on an opposite end; (d) inserting each inlet spud into a respective aperture; and (e) sonic welding an energy director on each spud into a respective said aperture.
