Buttress to NPT Adaptor 2″ x 2″


Many drums and lids for IBC Totes come with a buttress thread opening.  The problem is that the “buttress” thread doesn’t fit most standard pumps.  This buttress adaptor solves that problem.    The Buttress to NPT Adaptor 2″ x 2″ will thread into the buttress thread on your drum or IBC Tote lid and adapt to a 2” female NPT thread that you can use to connect standard pumps such as a Dura-Pump™.


Don’t know what thread you have on your drums? Here is how you tell the difference between buttress and NPT threads:

A way to distinguish between NPT and Buttress threads is by their appearance. Buttress threads have a thread where there the lines are spaced further apart making them look more coarse. So they are sometimes called “coarse threads”. NPT, by contrast, has threads much closer together so they are often referred to as “fine threads”.
