ABSTRACT:
A bin aeration device includes a skirt mounted to a bin wall by a stem including an exterior surface with a first portion having straight American National Standard pipe threads. A second portion on the exterior surface includes American National Standard Taper Pipe Threads. The American taper pipe threads permit attachment of either an internally American taper threaded fitting or an internally British taper threaded fitting if provided with 1/2 inch or 3/4 inch--14 threads per inch threads. An interior surface through the stem defines a passageway for pressurized gas to exit through an air port adjacent the skirt. A portion of the interior surface of the stem includes British Standard Taper Pipe threads. The British taper pipe threads permit attachment of either an externally American taper threaded fitting or an externally British taper threaded fitting if provided with 1/2 inch or 3/4 inch--14 threads per inch threads. An alignment land is provided on the stem with an appropriate size to permit positioning of the land in a hole drilled by certain standard American drill bits or certain standard metric drill bits.
