This is a "spare" or upgrade part, perfect for customers who've already bought a kit but who want to swap to a bag instead of a box.
See related items below if you would prefer to upgrade to a different box tank.

Unlike the box part these units are not customisable so there is no opportunity to choose a bag with additional valves.

All Bag parts are 220ml capacity

Note: This item does NOT include any tubing or vent parts
