Taco Hy-Vent - Automatic Air Vent - 1/4" NPT

Hy-Vents purge unwanted air from hydronic systems, keeping them running efficiently and quietly. When air is trapped in pipes and valves, it leads to disruptive noise levels and lost heat energy. The 426-3 uses a float type venting action that detects and expels air automatically. Adding Taco Hy-Vents to your hydronic system is a straightforward, smart way to keep everything running reliably and effectively. Product Features Simple Servicing Hy-Vent automatic air vents feature an easy-to-remove vent cap that allows for quick spot checks and uncomplicated maintenance. Alternatively, this vent cap may be sealed for safe system servicing. Bubble Breaker The 426-3 has a small, bubble-breaking fin at the base of the unit. This fin extends into your pipe where it disrupts large air bubbles, making them easier to vent.
