The 1/2″ Brass Auto Air Vent with Check Valve is the perfect upgrade for Vaillant boiler and central‑heating systems. Designed to work automatically, it continuously expels trapped air so your heating runs smoothly without the hassle of manual venting. The vent’s brushed‑brass construction resists corrosion and tolerates high temperatures, while the integrated check valve prevents back‑flow, keeping the system safe and efficient.
Installation is straightforward thanks to the 1/2 BSP male thread connection, and a shut‑off cap lets you pause the automatic function whenever needed. Whether you’re replacing a worn part or adding a new vent, this component fits seamlessly into existing Vaillant setups.
