The lower housing has an inlet opening formed therein for a sealable introduction of an inlet for the fluid regulation control device. The lower housing also includes an outlet opening formed therein for sealable introduction of an outlet of the fluid regulation control device. The lower housing includes a lower section having a sealed lower end and an open upper end. The upper end has an upper edge surface with recesses thereon forming lower segments of the inlet and outlet openings. The lower housing also includes an upper section having an open upper end and an open lower end. The lower end of the upper section has a lower edge surface which is sealably attachable to the upper edge surface of the lower section.
