Tube is made of PEI, although a strong one, please be careful if you use tank cracker juices, like cinnamon, strong menthol, citrus, cola, etc. This is a bottom fill tank section only, you need a Dvarw MTL FL 24 deck to have a working tank.
A spare glass tube will NOT work in this tank! Total length of the tank (deck+ultem tank section) is 27,1mm without drip tip and the 510 and has a capacity of 3,8ml.
