POPP M28 x 1.5 Thermostat Adapter for Radiator Valves

POPP thermostat adapter for M28

The POPP M28 x 1.5 thermostat adapter is a mechanical fitting designed to mount smart thermostatic valves (compatible with the M30 x 1.5 standard, such as many POPP or Danfoss valves) onto radiator valve bodies with an M28 x 1.5 thread (common on Herz, Comap brand radiators, etc.).

It allows you to properly attach the smart device to the radiator, ensuring a secure fit and the correct pressure on the valve stem.
