ABSTRACT:
A gas filter comprising a tube open at one end for insertion of the element and a threadedly connectectable end cap for closing the housing are disclosed. Attached to the end cap and also to the opposite end of the housing are receptacles for receiving the ends of the filter therebetween. The receptacles are faced with a resilient seal to make the connection between the receptacle and the filter air-tight as the end cap is tightened. After effecting the seal at both ends of the filter, a pair of hollow hypodermic needles pierce membranes that closed off the ends of the filter. The other ends of the needles extend out of the housing at both ends allowing the connection of an inlet and outlet gas hose thereby establishing fluid communication between the hoses and permit gas to flow through the filter for cleansing. Two embodiments are disclosed. In one, the movable end cap is prevented from rotating thereby precluding the transmission of rubbing action between the seal and the membrane during closure of the housing thereby aiding in preserving the integrity of the membrane until it is pierced.
