Flush mount fitting for gas emission sample container

摘要

A gas emission sample container has a fitting mounted in an aperture formed in one side wall of an expansible body. The fitting includes a sleeve with a through bore and an enlarged diameter end collar. A ring member is mountable over the sleeve in surrounding engagement with the collar and traps the edges of the side wall of the container surrounding the aperture in the container therebetween. A lock nut threadingly mounted over the sleeve removably fixes the ring member over the collar with the exterior end of the collar being disposed substantially flush with the end of the ring member and the major portion of the side wall of the container. A coupler nut is connected to the sleeve for connecting the interior of the container and the fitting to a gas flow conduit. A seal is mounted about the sleeve between the collar and the ring member to form a seal between the edges of the side wall of the container surrounding the aperture in the container and the fitting.
