This RO Storage Tank Ball Valve (Tank Shut-Off Valve) is designed for reverse osmosis (RO)
pressurized storage tanks. It features a 1/4″ FPT (female pipe thread) inlet that connects to
the tank stem and a 1/4″ Quick Connect (push-fit) outlet for standard 1/4″ OD RO tubing.
Use it to easily turn your RO tank water supply ON/OFF for service, filter changes, or troubleshooting.

The built-in ball valve provides smooth, reliable shut-off. The quick connect port allows fast installation—
simply push the tubing in until fully seated for a secure, leak-resistant connection.
