Maid O' Mist No. 71 Auto-Vent
M**E
Di oesn't last as well as the older versions.
I use these on a oil processing unit on Inlet and outlet filters. Original ones lasted 8 years. Newer models failed after one month. The crimped cap seal both leaked a week apart after a month. Now I install with a shutoff below vent and isolate after I start vacuum and hopefully prolong the life.
