Abstract

A removable device that ensures that the port of a filter cartridge is liquid tightly sealed to the port of the head of a housing even when there is insufficient room beneath the bowl to allow one to physically secure the cartridge port to the head port before securing the head and bowl together. The invention uses one or more removably attached alignment devices to center the cartridge in the bowl and maintain it at a height sufficient to ensure that the two ports are aligned and liquid tightly sealed to each other when the bowl and head are mated together.
