The 34DS – 34 Litre Steel Non-Refillable cylinder is available for non-corrosive gas mixtures such as hydrocarbons, CO, CO2, O2 or N2 whether it is a single gas or a complex blend.
This cylinder is used primarily because of its small size.
It is important to note that the valve is a CGA600 which requires a specific regulator – either the FF-120 or the ODFR-600
