Prevent drum failure by using these vents to release pressure and vacuum buildup caused by draining liquids and sudden temperature changes. In case of fire, a flame arrester prevents flashback into the drum.
Style D has a removable cap so it can be used as a fill opening.
Style E comes with two carbon filters. The filter traps 99% of vapors.
