1/2" Narrow Bottle Air Vent

The 1/2″ Bottle Air Vent is a high-quality brass component designed to improve the efficiency and safety of heating systems by automatically releasing trapped air and expansion gases. Fitted with a 1/2″ male thread, this vent is installed at high points in pipework where air naturally accumulates. As the system fills with water, air escapes through the vent until the water level rises and forces the internal float upwards, sealing the vent and preventing water leakage. When air or gases build up again, the float drops, allowing them to be expelled automatically, ensuring smooth system operation and protecting against issues such as noise, corrosion, and reduced circulation.
