Taco 419-1 Hy-Vent 1/2" x 3/4" NPT Automatic Air Vent 250 PSI

The Taco 419-1 Hy-Vent is a float-style automatic air vent designed to efficiently remove air from hydronic heating and cooling systems. This compact venting solution features 1/2" female NPT inlet and 3/4" male NPT outlet connections, making it versatile for various piping configurations.

Key Features:

• Float-style automatic operation eliminates manual venting
• Maximum working pressure of 250 PSI for demanding applications
• 1/2" female x 3/4" male NPT threaded connections
• Brass construction for durability and corrosion resistance
• Compact design for easy installation in tight spaces
• Removes trapped air automatically to improve system efficiency

The Hy-Vent automatically releases air that accumulates in hydronic systems, preventing noise, improving heat transfer, and reducing pump cavitation. The float mechanism closes when water is present and opens to vent air, ensuring continuous system performance without manual intervention. Ideal for boilers, baseboard heating systems, radiant floor heating, and chilled water applications.
