6" 8oz Emergency Vent Male Thread


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 requirement.

Code Compliance

When properly sized for the tank, this vent will conform to the requirements of the International Fire Code; National Fire Code of Canada; National Fire Protection Agency—NFPA 20, 30, 30A, 31, 37, 110; Petroleum Equipment Institute—PEI RP200, PEI RP800; Underwriters Laboratories Inc.—UL-142, UL-2085, UL-2244; Underwriters Laboratories of Canada—CAN/ULC S601, CAN/ULC S602, CAN/ULC S652
