This is a spigot suitable for 20L containers. Price is for a set of 3. These are unused, new spigots, leftover from home use. I am not selling these for business purposes; they are surplus, new, and unused spigots from my personal use. I cannot guarantee or answer questions about compatibility with specific manufacturers or brands of water tanks. Please understand that these are stored at home and are used items, so please purchase with that in mind. They will be packed compactly for shipping. #spigot #watertank #watertank
