JG Polypropylene Ball Valves shut off the flow of the water to and from equipment with a 1/4 twist of the handle. JG PPSV500822W ball valve connects to a 1/4" OD tube using Speedfit (Quick Connect, QC) fitting on one side, and is 1/4" Female NPT threaded on the other side. John Guest elbow ball valves are commonly used as the RO tank shut-off valve (tank valve) in home RO systems to provide the means of stopping the water flow to and from the tank during service.
