Heater valve repair kit comprising diaphragm and the cast body with outlet pipe. Does not include the end plate with the control levers. This kit is the closest we can find to service the valve, the body and diaphragm are correct, but most of the small pieces are wrong. since in most cases it is only the body which is corroded and the diaphragm hardened, this kit will do the job. Suitable for all TD/E/F 21 models except early TD with slider heater controls.
