Hi Bezzy4986,
These have 1/2" BSP female threaded fittings at each end, and so without additional fittings would not be compatible with the (usually) 1/2" BSP female threads on the radiator. However, if you mean with regard to temperature, this hose is rated for a maximum operating temperature of 70°C and I believe that some heating systems may go as high as 80°C for the radiators.
Thanks for using Screwfix Q&A. JT
