Myson Radiator Bleed Valve / Air Vent

Air vent / bleed valve for newer Myson central heating radiators (made after June 2003).

Measures 11mm across the flats of the hexagonal part, the screw thread has a diameter of 7mm.

Does NOT fit any other brand of radiator.

This is what it looks like in use, this vent is white, as it was fitted in the factory and then painted white along with the radiator.
