Drum-plug caps (sold separately) fit over drum plugs to provide dust protection as well as evidence of tampering. They have a breakaway seal and are for one-time use.
Metal Drum Faucets
All of these faucets are primarily used on drums, but can also be used on tanks, carboys, and other containers. If your drum has a 2" Buttress or Mauser thread, use drum thread adapters to attach drum faucets with pipe size 2 NPT threads.
Style C has a locknut with a rubber gasket that allows you to position the spigot in any direction. The locknut also provides a tight seal, even on drums with oversized or damaged threads.
