This a replacement part for a standard Reverse Osmosis (RO) System. All tube connections are 1/4″ with “in” and “out” labeled on the top.

This valve shuts off the feed water going into an RO System when the pressure on the tank side reaches 2/3 that of the feed pressure.

We recommend using tube stiffeners in the ends of all tubes when using Jaco Style Fittings. Tube stiffeners can be found at the bottom of this page.
