FAQs
Will these fit all radiators?
These keys are designed for standard 5mm clock-type bleed valves, which are the most common in domestic heating systems, but they will not fit valves requiring flathead screwdrivers or larger square drives.
Why do I need 25 keys?
This bulk pack is intended for professional maintenance, letting out properties, or simply ensuring you have extras stored near every radiator or in different toolkits.
Can I use these while the heating is on?
It is strongly recommended to turn off your heating system and let the radiators cool down completely before bleeding to avoid injury from hot water or steam.
How do I know if my radiator needs bleeding?
If your radiator is cold at the top and hot at the bottom, or if you hear gurgling sounds, there is likely air trapped inside that needs to be released.
Are these keys made of plastic or metal?
These keys are manufactured from durable metal to withstand the torque required for stubborn radiator valves.
Troubleshooting
Key slips inside the valve
Ensure the key is fully inserted into the square head of the bleed screw. If the valve is rounded, the key may not grip effectively.
Valve will not turn
Apply a small amount of penetrating oil to the screw and wait ten minutes before attempting to turn it again with the key.

Setup, Compatibility & Care
This tool is designed for universal compatibility with standard domestic radiators utilizing a 5mm square-shaft clock-type bleed valve. No complex setup is required. To ensure long-term utility, store these keys in a dry toolbox to prevent surface oxidation. If a bleed screw is excessively tight, ensure the key is fully seated before applying pressure to prevent rounding the edges of the valve or the tool.
