Fuel Line Bulkhead Fittings

Somebody mentioned using fuel line bulkhead fittings on their bottle tops for DIY CO2. I just recieved some and want to install them, but don't know if I need to use some kind of a gasket with them or just tighten them up on the bottle tops.

Just tighten them up on the bottle cap. I make a small hole with a hot wire and remove any shavings with a sharp knife tip first. Then just tighten them down. The bottom of the cap itself acts as a gasket. It makes sense since it keeps CO2 in a pop bottle. The gaskets get old sometimes and then I use a new bottle cap.

Again, thank you Tempest.
