FlameTech PNG 20A Inferno Heavy Duty Heating Head PropaneNatural Gas Size 20 Harris Compatible Tested in The USA

FlameTech Inferno head is designed to operate with propane or natural gas. Shells are machined from solid copper bar stock. Internals are machined from Brass which is press fit and Pinned to prevent separation during backfire. Large heating assemblies require high volumes of gas to keep Flames burning properly.
