Torque Required for Drum Closures & Plugs

Torque required for drum plugs and closures

What torque to use on drum plugs and closures?

This is the force that needs to be used by employees that close the drum openings. Since Contech sells drum plugs, we feel it’s necessary to provide information on how to use them; in this case, what strength to use on the torque wrenches. If there is too much torque for closing drum plugs, they can be broken; the drum plug and gasket can get deformed and cause a leak. If there is too little torque on drum closures then they don’t close the plugs tight enough, and the drum can leak.


“I purchase all of my steel line bungs from you and you have always been helpful and fair in negotiating our pricing for our bungs. You are always easy to get in touch with and respond back to me in a timely fashion which is becoming rare these days with many of my other vendors. You are, by far, one of our preferred vendors.”

The DOT (Department of Transporation) has laws that require ALL manufacturers and reconditioners of drums (plants that clean used drums) to have these TORQUE requirements to avoid any accidents because sometimes the contents inside the drum are toxic or flammable and can cause really bad accidents, such as highway accidents.

So, many Contech customers call for drum closure torque information, so we now provide it in the chart below.
