MB 245 Female Emergency Vent
Morrison Bros 245 8 oz. Emergency Vent - Female Threaded w/ O-Ring.
UL Listed emergency vent (pressure relief only) used on aboveground storage tanks, as a code requirement, to help prevent the tank from becoming over-pressurized and possibly rupturing if ever exposed to fire. The vent must be used in conjunction with a “normal vent.” Correct application of this vent requires proper vent size and selection for the tank system in order to meet the specific venting capacity.
