Purchased to add helium to argon to TIG thicker aluminum than with straight argon.
Was hoping, because the western connector had arrows for flow direction, that it contained 2 check or one way valves. Unfortunately it does not have check valves.
Hopefully I can use it after adding separate check valves and I can use it with a flow opposite of the arrows or can flip the 2 fittings around so the flow matches the arrows.
