About this item
- Wide brand compatibility: the radiator adapter is compatible with valves from COTERM as well as COTHERM with M28 x 1.5 mm thread and allows the installation of modern thermostatic heads with M30 x 1.5 thread on older radiators. In addition, it is compatible with standard smart home systems such as AVM, Devolo, Fritz!, Fritz!Dect301, Fritz!Dect302, innogy, Moes, Heimeier Homematic, Honeywell and Tado for a variety of intelligent heating controls.
- HIGH QUALITY MATERIAL FOR DURABILITY: Made of durable brass, this adapter offers excellent corrosion resistance and lasting stability. It is optimally designed for years of use in the domestic heating circuit without material fatigue.
- Safe operation of the thermostat: the valve adapter creates a firm, tight connection between the radiator valve and the thermostat head. This guarantees stable functioning as well as accurate, even temperature control throughout the heating area.
- Easy and quick installation: thanks to the precisely manufactured double thread, the adapter can be attached in a short time without special tools. It is equally suitable for professional installers as well as private DIY enthusiasts for renovation work.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
