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 418-4 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. Dual Thread Design The 418-4 Hy-Vent is dual threaded for installation flexbility. It features a 1/2″ FPT connection and a 3/4″ MPT connection. 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.
