Drum Plugs

For installation and removal of these plugs, use drum-plug wrenches.

Style D have a M64 thread size, which is also known as Buttress threads.

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.

Lockable Breather Vents with Cap

Secure access to vented openings in pipe and tanks—the cap can be locked to prevent tampering. These breather vents allow you to add a filling port to your hydraulic tank while protecting against excess pressure and vacuum. Use them to stop debris from entering your tank. Breather vents mount on top of standard tank openings with included hardware. Padlock is not included.
