MAID-O-MIST 9AS AUTO SHUT OFF

Maid-O'-Mist® Shut-Off Valve, 1/8 in Nominal, Male Connection

The number 9AS shortstop is an automatic shut-off that saves hours when changing out Maid-O'-Mist vents with 1/8 in male connections. This accessory is a spring loaded shut-off that stops the flow of water automatically when the vent is removed and re-opens when a new Maid-O'-Mist vent is installed. With a shortstop in place, it is no longer necessary to drain the system to switch out vents.
