NC Tool Natural Gas Orifice

High-Pressure Venturi Orifices needed to switch an NC Forge from Propane to Natural Gas.

**Note - these are specific for HIGH-PRESSURE natural gas forges, and will be too small for installations that use standard residential gas pressures (Standard Low-Pressure gas lines run at about 4 oz pressures vs a commercial 10 lb high-pressure line).

We have multiple orifices & fittings, multipacks and kits in our shop not yet online. 

Contact us if you need help in the interim.  

We stock, source, and manufacture to suit.
