Shut off / commissioning cap for Myson TRV-2-Way thermostatic radiator valve

M30 (30mm) thread

 

When you are removing a radiator for decoration or repair purposes and this radiator has a Myson thermostatic valve fitted you should be aware that this valve sometimes can not give a 100% shut off. Also, even though you turn the valve off, a drop in room temperature can cause it to open with resultant flooding.

This cap is used to temporarily replace the thermostatic head for peace of mind.
