⚠️ IMPORTANT – PLEASE MEASURE BEFORE ORDERING!

Radiator valves and fittings can vary between manufacturers and models. Please measure your existing fitting carefully before purchasing to make sure these caps are suitable.

Although designed to fit standard 20mm fittings, compatibility cannot be guaranteed with every radiator valve.

Please check the dimensions of your existing cap or fitting rather than relying on appearance alone. If you're unsure, feel free to ask before ordering.
