This listing is for 3x Tado supplied Tado M28 x 1.5mm Type Thermostatic Radiator Valve Adapter.

The adapter is suitable for BOSS Therm, COMAP, Herz, MMA, Myson, Pegler, SALUS, SIEMENS, Sunvic and others with a 28mm x 1.5mm thread.

This will convert the radiator valve to a M30 x1.5mm male thread to allow the fitment of most M30 x1.5mm Smart Electronic Radiator Thermostats.

Allows the easy fitment of Honeywell Evohome HR92 HR91, Tado and many other modern electronic TRVs. 

It is supplied with 4 different length drive pins, 24mm, 18.5mm, 17mm and 15mm to suit differing valve bodies.

With your old head unscrewed from the valve, please check your radiator valve has a M28 x 1.5mm thread, as the adapter is only suitable for this type of radiator valve. See pictures for further details.

Further info is available on Tado’s website.

Please feel free to contact me prior to purchase if unsure of adapter required, and I can assist in adapter type selection.

Please contact me prior to purchase if more are required or other types needed, as these can be added to your order.
