This buttress adapter has a 63mm opening. It fits Russell-Stanley®, Sonoco®, Greif® and most other US made plastic drums. No need to make do when using standard 2 inch 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.
Note: Check both the opening size and the drum type before ordering. Call a BASCO Customer Service Expert for details at 1.800.776.3786.
