The unit is manufactured from cast iron and features equal threaded inlets on both sides. Top of the air scoop features a 1/8" NPT outlet and allows for connection of a regular air vent (such as Taco Hy-Vent part# 400-4). Bottom of the air scoop has a 1/2" NPT threaded outlet, which allows for connecting a plain steel diaphragm expansion tank.
