Taco 3/4" Commercially Rated Brass Vent

The Taco 409 air vent is a heavy duty brass vent rated to 150 psi system operating pressure. The conical shape of the vent significantly increases the clearance between the water level and internal mechanisms, reducing the potential that dirt floating on the top of the water could foul the venting operation. It features a convenient outlet connection for a 3/4" ID flex tube waste connection. It's high capacity design makes it ideal for placement throughout commercial systems. Replaces 409
