These carbonation caps are now available in yellow to help differentiate between gas and liquid posts. Liquid = Gold is all you need to remember. Add your silicone dip tube to this cap and never risk accidentally attaching your gas line. Note: It is a multi post, so it will take both gas or liquid if you want to change it up.
This product is made from high quality engineering plastic and will last a very long time. It’s chemically resistant and also designed ot resist impact and physical damage.
