FAQs
Are these keys compatible with all radiators?
They are compatible with almost all standard UK radiators that use a 5mm square bleed valve.
Is it safe to bleed radiators while the heating is on?
No, it is highly recommended to turn off the heating and allow radiators to cool to prevent accidental burns from hot steam or water.
Why do I need 100 of these?
This pack is primarily intended for landlords, building managers, or maintenance teams who service multiple properties.
Does the brass material rust?
Solid brass is corrosion-resistant, making these keys ideal for long-term storage in utility cupboards.
Can I use these on electric radiators?
These are designed for hydronic (water-based) central heating systems. Do not use on electric radiators as they do not contain bleed valves.
Troubleshooting
The key feels loose in the valve
Verify that your radiator valve is a standard 5mm square type; if the valve is stripped or damaged, the key may not grip effectively.
The valve will not budge
Do not force the key. Apply a penetrating lubricant (such as WD-40) to the valve threads and let it soak for 15 minutes before trying again.
Water continues to leak after tightening
Ensure the valve is fully seated and tightened. If the leak persists, the internal valve washer may have perished and require a professional plumber to replace.
Pros and Cons

- Fits standard UK 5mm radiator valves
- Bulk quantity is highly cost-effective for professionals

Setup, Compatibility & Care
These keys are engineered specifically for the UK market and are compatible with standard 5mm square radiator bleed valves. No specific setup is required; the tools are ready for immediate use out of the box. To maintain the integrity of the brass material, store the keys in a dry, low-humidity environment to prevent tarnishing. If the valve is rusted, ensure you use the key carefully to avoid stripping the valve head; applying a small amount of penetrating oil before usage can help if the valve is stuck.
