Threaded non-return valve in stainless steel.
Only allows flow from the male thread to the female thread. Permanent marking shows flow direction.
The check valve prevents liquid from traveling up into the gas system (which can otherwise happen if the liquid level is above the gas dip tube and the pressure in the keg is higher than in gas line).
Made of stainless steel and can easily be taken apart for cleaning.
