Our DOT-4BW240 cylinders arrive to you equipped with an internal liquid dip tube attached to an external liquid withdrawal port. The withdrawal port is a standard CGA-555 connection.
IMPORTANT: We will not buy back any cylinder that has been damaged to a condition that prohibits its legal transportability under current DOT regulations (i.e. if your cylinder ring is bent, the valve is not fully operational, the cylinder body is dented, or the cylinder leaks, we will NOT buy the cylinder from you). If your cylinder is damaged on arrival, please let us know within the first 24 hours of receiving it.
