What is a "Bung Opening"?

The holes on top of the drum or on the drum's lid are called "bung openings ". All closed-head drums come with bung openings (in order to get product in and out), but not all open-head drum lids do. All drums with bung openings come with threaded plugs to keep the contents inside.

Plastic drums generally have two openings that are each 2 inches. One has course threading (known as a "buttress plug") and the other opening has fine threading (called NPS, also known as national pipe straight thread).

Steel drums come with two different sized bung openings. One is a 2 inch opening and the other is 3/4 inches. Both have fine threads (NPS).

Knowing what type of bung opening your drum has is important because the accessories you buy for your drum attach at the opening. In other words, you wouldn't want to buy a faucet for a 3/4 inch opening if you are buying a plastic drum with only two 2 inch fixtures.
