I made my own out of 4" sch. 40 PVC pipe and 2 caps. Drill and tap for 1/4" pipe each cap, and glue them on. The pressure rating of the pipe is 133 psi, way more than any torch will use. The nice part is that you can cut the pipe any length you want and mount it up under your bench out of the way. I have 5 of these with 5 ogsi 20 lpm oxy-cons. System runs great with no fluctuations because I tied them all together.
