No. 7 Series Auto-Vents®The No. 7 Series Auto-Vents® are reliable, automatic air eliminating valves for concealed radiators, pipe lines, tanks and other devices where water or liquids are used for heating and cooling. They have proven to be the solution to problems that have confronted engineers and contractors in which air pockets or traps retard the free circulation of the liquids and reduce the efficiency of the system or appliance. The No. 7 Series Auto-Vents® air eliminators are made of brass and equipped with a self-closing, float-operated valve. The valve is equipped with a Monel® metal spring and a Neoprene® valve seat which is unaffected by high temperatures, oil and anti-freeze. No air chamber is required. The vent is regularly fitted with a patented cap that may be used as a check in case of a leak caused by core sand or scale.
No. 66, 67, 68 Auto-Vents® and AccessoriesThe No. 66, 67, 68 Auto-Vents® are float-operated vents for use on convector radiators, baseboard radiation and radiant panels. These are designed to be used in space that is limited and can be installed in trouble spots previously neglected or improperly vented. No air chamber is required. The No. 66, 67, 68 Auto-Vents® are designed for systems with pressures up to 50 lbs.
The No. 9AS 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.
In situations where safe waste is required by law or areas particularly susceptible to water damage, the No. 7A Connector is used to connect 1/4” copper or plastic tubing to the venting port of Maid-O’-Mist® vents. In this manner, any spray caused at system start-up or leaking caused by scale in a system can be safely directed to a drain.

Great for tight spaces where vents requiring a key or coin are not practical.
