The invention is a method for joining two components of a fluid system. The method involves forming a first flange on a first fluid component and placing the first flange in an abutting relationship with a second flange that is formed on a second fluid component. The abutting relationship may be such that conduit portions of the fluid components are axially aligned. The flanges may then be bonded together such that the bond encircles the conduits and prevents fluid from entering or exiting the system from the bond. A bond of this type also places the first and second components in fluid communication. The fluid system may be incorporated into a sole structure of an article of footwear.
