Cleaning out some stuff. I have a GLA Smith Regulator, it works really well even though it is a single stage. It comes with 2 SMC needle valves to use on 2 tanks, the hose barb in the needle valve can be removed should you need to close one valve and use for 1 tank only. I will include a screw plug for the needle valve. Fully tested with no leaks and ready to use. $150 for this regulator, price slightly negotiable. I will include 2 barb slicers for hose connections as well. PM me with any questions.
