1 1/2" MIP Threaded Plain Auto Vent is manufactured by Jones Stephens and is used in many plumbing applications. It is most commonly used for plumbing applications such as basins, sinks, tubs, vanities and showers, but should never be used with toilet applications. Every drainage system uses and is required to have a proper functioning main vent stack. This Auto vent is an inexpensive way to cap off other vent stacks as secondary vents.
