This brass clock-type radiator key is intended for venting trapped air from radiators within central heating systems. It provides a straightforward method for ensuring radiators are properly bled during installation, repair, or ongoing maintenance.
Supplied pre-packed in a heat-sealed bag, the key is easy to store and keep secure in toolkits or on site. Commonly used by plumbers and heating engineers, it serves as a practical replacement part for routine radiator servicing and upkeep.
