ABSTRACT OF THE DISCLOSURE A multiple canister mount for receiving at different times different sized bolt connectors of canisters for protective masks and the like. The device comprises a base and a pair of spaced annular rims secured to and upwardly projecting from the base. The inner wall of each rim is threaded with threads of appropriate form, and is of a diameter, so as to receive a canister bolt connector of particular size and having a particular thread form. The outer rim is formed of metal, and the base and inner rim are of integral plastic construction. The outer rim is clipped securely to the inner rim and base by means of an annular flange upwardly and inwardly extending from the base of the outer rim, the flange inwardly bearing against the outer wall of the inner rim. A sealing means is provided between the inner flange and the outer of the inner rim to prevent passage of air therebetween. The device also comprises a centrally disposed valve opening and valve seat secured to the base. Such a device provides a simple effective means for securing canisters, which may have different sized bolt connectors, at different times to the same protective mask.
