Description
Both natural gas and propane gas can be used in gas grills, but the burning conditions are different. The 1/2”male flare to 3/8”female flare convertor adapter allows you to use the hose for your 3/8" male connector propane appliances. 
Natural gas burns a little cleaner than propane gas, and it's more convenient than a propane tank that always needs to be carefully filled.
