COMBINATION BREATHER-DRAIN ABSTRACT OF THE DISCLOSURE The combination breather-drain is designed to be disposed in the bottom of an explosion proof housing to facilitate the drainage of moisture from the hous- ing by gravity while simultaneously providing an atmospheric communication with the interior of the housing through a separate passage. The passage for the drainage of moisture is defined by a loose threaded connection between a hollow cylindrical plug and a fitting secured to the bottom of the housing. The threaded connection is so dimensioned as to pre- vent the passage of a flame through the threaded connection. A plurality of baffles or a solid threaded plug are provided in the interior of the hollow cylindrical plug to provide an air passage so dimensioned as to prevent the passage of the flame therethrough.
