Abstract: A fluid delivery manifold and a method of manufacturing a fluid delivery manifold is provided. A first manifold portion having a contoured interior face is set in registry with a second manifold portion having a contoured interior face to form an uncoupled manifold having a plurality of fluid inlets and a plurality of fluid outlets. The contoured interiors of the first and second manifold portions form a plurality of material channels and a plurality of fluid channels in the uncoupled manifold. A second shot material is injected into the material channels to couple the first and second manifold portions and to compensate for any variation or differences between the pitch of the fluid inlets and fluid outlets.

Abstract: A molded plastic, push-on fastener for connection to threaded studs or the like comprises first and second cylindrical collar members. The first collar has a resilient side wall and threads are formed on the interior thereof in a form and size for positive engagement with the threads on the associated threaded stud. The second collar member has a relatively rigid side wall with an open interior diameter which is greater than the diameter of the first collar member to permit the second member to be received over and surround the first member. A thin frangible, connecting web is provided for temporarily connecting the collar members in axial alignment. Cooperating interengaging thread forms are formed on the exterior of the first collar member and the interior of the second collar member.
