A test port and bleed valve is combined in a unitary main body of a device. A split core test plug is positioned within a hollow valve stem. The seal at the bottom of the valve stem engages a valve seat to provide a releasable airtight seal. At the top of the valve stem, rotating the stem so that it axially moves toward and away from the valve seat to open and close the valve to bleed gas from the vessel or piping system. A bleed port is located through the sidewall of the main body of the device so that it is in fluid communication with the working medi...


1. A test plug and gas bleed fitting, comprising:a main body having first and second coaxial bores, the first bore being of lesser diameter and extending downwardly for fluid communication with a vessel or piping to which the main body is affixed;the second bore of larger diameter extending upwardly through a top end of the main body and including an annular valve seat at its base where it meets the first bore, said second bore including a threaded region adjacent the top end thereof;a hollow valve stem having an externally threaded region engaging said ...
