The Nitrous Express blow down tube plumbing kit includes an 8AN nut, sleeve and an aluminum tube bent 180 degrees so nitrous will discharge downward out the vehicle if a safety blowout disk ruptures. The assembly provides a reliable path for safe external discharge per common safety practices, simplifying installation of a blow-down tube to compatible bottle valves and fittings.
