Abstract: An adapter to connect a portable testing device known as the Joint Service Mask Leakage Tester (JSMLT) to the outlet valve body of a protective mask such as the M45 mask for testing and validating the operation of the outlet valve of the mask prior to use.

Abstract: An adapter for testing an outlet valve of a protective mask with a testing apparatus includes portions which oppose the valve and are configured to connect the valve to the tester in sufficient isolation for testing purposes. In one implementation, the valve has first and second notches configured to engage corresponding non-uniform geometries in an interference fit. In still further implementations, the adapter comprises an overmold with a resiliently compressible surface conformed to mate with the outlet valve and an insert at least partly encapsulated by the overmold and providing support to the resilient compression of the surface of the overmold. In use, the portions of the adapter engaging corresponding locations on the valve to be tested form an interference fit.

Abstract: The invention relates to devices and methods for adapting a standard protective mask test apparatus to perform leak testing of a mask air hose assembly as an independent equipment component, i.e., independent of the mask-hose system.
