Due to the extremely low boiling point of nitrous oxide when delivered as a LIQUID under vapor pressure, there is NO need to use a nozzle designed to vaporise it (as is the case with a liquid fuel), because it will naturally vaporise as it exits ANY nozzle and makes contact with any other media.
Furthermore, if you tried to pass LIQUID nitrous through a nozzle designed to achieve atomisation of a media, it would fail as it would cause internal freezing which would create a restriction to the flow.
All you need is a tube/nozzle with a smooth & constant bore of a suitable size to flow the amount of nitrous you want to flow.
Adding a suitable angle to the outlet 'edge' of the internal bore, will reduce the risk of freezing at that point and reduce flow losses due to turbulence.
Our Discharge Tubes are the ULTIMATE way to flow/discharge nitrous;
