Jacobus - Maid O Mist Auto Vent with Automatic Shortstop Shutoff

The No. 67AS Shortstop is an Automatic Shut-Off that saves hours when changing out Maid-O’-Mist® vents with 1/8” 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.
