The Nitrous Express 3AN x 5/16 NPT nozzle systems rail fitting is made for nozzle system rails, providing a 3AN connection that transitions to a 5/16 NPT nozzle port. It lets installers mount nozzle outlets on a rail while matching common NPT nozzle sizes, useful in nitrous or fuel distribution setups where rail-mounted nozzles are required for consistent flow.
