Decorators Cap For Cylindrical Shape Thermostatic Radiator Valves (TRV's)
1x Decorators Cap for fully closing off TRV valves. Used when radiators are being removed for re-decoration of walls behind.
In order to fully close off a thermostatic radiator valve (TRV), the TRV head will need to be removed and replaced with one of these plastic decorators cap. This ensures a water tight seal. Without this, the frost protection feature on thermostatic radiator valves, prevents the valve from completely closing off, so it is possible that water can still seep through. This cap contains any seeping because it is a screw tight fit connection.
