Pipe masking set specially for 50mm pipe connections - to cover the exit point for your valves from the wall and into the back of your radiator. Gives the perfect finish with a flat plate for the wall and matching pipes. These can be seen in some of the lifestyle shots of Terma radiators - so this is the accessory needed to achieve that look. Pipes are 18mm in diameter (16.5mm internal diameter) so will sleeve over 15, 10 or 8 mm diameter copper pipework. Chrome in colour.
