You already know Taco Hy-Vents as the industry standard for dependable, long-life service. The high-capacity, float-style vent can be placed either on the boiler or at the high points throughout the system. With threaded connections--1/8". 1/4", 1/2" and 3/4" - and operating pressure ratings up to 250 psi, these brass-body, nickel-plated vents meet the system requirements of even your largest installations. Vents are easily serviceable, if needed, by simply unscrewing the vent cap. Taco Hy-Vents are available in a variety of styles including the Slim-Line Hy-Vent and High Pressure Hy-Vent.
