Radiator Vent Plug - Chrome

Radiator Vent Plug - Chrome

The Radiator Vent Plug (also known as a radiator bleed valve) is an essential component fitted to the top corner of a radiator to allow for the manual release of trapped air from the central heating system. Manufactured with a high-quality chrome finish, this plug is designed to blend seamlessly with modern designer radiators, towel rails, and standard panel radiators that feature chrome or polished accessories.

Air trapped in a radiator prevents hot water from filling the unit completely, leading to "cold spots" and reduced heating efficiency. This vent plug features a central screw that, when loosened with a standard bleed key, allows air to escape until water begins to flow, indicating the radiator is fully purged.
