Radiator air vent with 1/8" plastic knob

Description:

The radiator air vent with plastic knob and 1/8" threaded connection is a manual device designed to release trapped air from radiators and heating elements in heating systems. The presence of air in the circuit can hinder the circulation of hot water, reducing thermal efficiency and causing noise or cold spots in the radiator.
This vent is typically made with a chrome-plated brass body, ensuring corrosion resistance and durability, and a white plastic or resin control knob for ergonomic and safe use during bleeding. The thread is made according to the 1/8" male standard (G 1/8"), compatible with the ventilation fittings of radiator cylinder heads.
The mechanism is simple: by slowly unscrewing the knob, excess air is released until water comes out, indicating that the entire circuit has been freed from air bubbles. This type of valve is mainly used when filling systems or during routine maintenance. It withstands pressures up to approximately 10 bar and operating temperatures typical of domestic systems up to approximately 90-100 °C.
