3/8 in. Female NPT x Female NPT Gas Ball Valve, AGA/UL/CGA
3/8 in. Female NPT x Female NPT Gas Ball Valve, AGA/UL/CGA
Overview
The Midland Industries 943201 is a 3/8 in. full-port brass ball valve built for fuel-gas service and certified to AGA, UL, and CGA. Its Female NPT x Female NPT (FPT x FPT) end connections, chrome-plated brass ball, and PTFE seats deliver bubble-tight shutoff at up to 600 PSI WOG across a -20 to 248 °F range. A quarter-turn reversible lever gives fast, low-torque open and close, and the blow-out-proof bottom-entry stem keeps the valve safe under pressure.

Typical Applications
Natural gas and propane shutoff, gas appliance and meter connections, air and oil lines, and general industrial or commercial flow isolation. The full-port bore keeps flow restriction and pressure drop to a minimum, making it a good choice where line capacity matters. Not for potable drinking water - see our lead-free valve guide below for NSF/ANSI 61 options.

Frequently Asked Questions
Is the 943201 approved for natural gas and propane?
Yes. It carries AGA, UL, and CGA approvals for fuel-gas shutoff service on both natural gas and propane.
Can I use this valve on drinking water?
No. This valve contains lead and is not certified for potable water. For drinking-water systems, choose a lead-free valve certified to NSF/ANSI 61.
What is the pressure rating?
600 PSI WOG (water, oil, gas, non-shock), plus 150 PSI WSP saturated steam.
What does full port mean?
The ball bore matches the pipe inside diameter, so the valve adds almost no flow restriction when fully open.
