Morrison Bros 244O Female Threaded Emergency Vent


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.

WARNINGS: The 244 emergency vent is for “emergency pressure relief only” and must be used in conjunction with a “normal vent” or pressure vacuum vent such as a Morrison Fig. 354, 548,748, 749 or 922. The 244 emergency vent must be properly sized and selected for each specific tank application in order to meet the proper “venting capacity” requirements. See the Morrison Vent Guide for further instructions.
