This Zoro Select vent provides automatic pressure and vacuum relief for vertical drum installations. It is designed for non-corrosive flammable liquids and fits a 3/4 inch NPS or NPT male pipe thread. The brass body includes a flame arrestor and two filters for added safety during operation.
Installation details
The vent threads directly into a 3/4 inch drum bung using standard NPS or NPT threading. Brass construction allows reliable sealing without specialised tools. Ensure the drum orientation is vertical as specified; horizontal mounting is not supported by this model.
