A support assembly comprises a mounting bracket and a coupling component. The mounting bracket comprises a first material and has an engagement surface defining a void along a first axis. The coupling component comprises a second material, which is different than the first material. The coupling component has a first end, a second end, and an intermediate portion. The intermediate portion extends through, and partially fills, the void defined by the mounting bracket. The intermediate portion defines a fluid passageway about the first axis within the void and also presents a locking surface. The locking surface abuts the engagement surface to prevent rotation of the coupling component with respect to the mounting bracket.
