3/8" pipe to 1/4" Female Thread Manual Valve (RO Tank Valve)
This fitting is used to connect 3/8" piping to a 1/4" male thread. The shut-off valve also allows you to open or "shut off" the water flow through the 3/8" piping to an endpoint. This valve is also the same type of "pipe to female thread valve", used on under-the-counter RO system tanks.
