2” Drum Buttress x 2” NPT Adapter
This buttress adapter has a 63mm opening. It fits most US made plastic drums. No need to "make do" when using standard 2" NPT threaded pumps and faucets and other equipment in plastic drums with buttress thread bung openings. This precision molded high-density polyethylene adapter will do the job right. Green in color. This adapter has a male buttress thread to thread into the buttress thread on a drum. It adapts the buttress thread to a 2" female NPT thread.
