Manual radiator air vent valve 1/2″ – chrome/white

The manual 1/2-inch radiator air vent valve is used to remove trapped air from radiators in hot-water heating systems. Air trapped in the upper part of a radiator can cause cold areas, uneven heating and noise during operation. Partially opening the bleed screw allows the air to escape before the valve is closed again.

The valve has a standard G 1/2″ or 1/2″ BSP male thread for installation into a compatible radiator connection. Its nickel-plated brass body provides strength and corrosion resistance, while the white plastic section directs discharged air and small amounts of water away from the radiator surface. An integrated rubber O-ring provides a secure seal.

The bleed screw is operated manually using a flat-head screwdriver. Open the valve slowly until the trapped air has escaped. Close it when water begins to flow steadily without air bubbles.
