We stock a range of adapters and reducers to fit all kinds of pipe fittings. They ensure the various parts of your central heating system (pipes, valves and radiators) can connect to each other - where the various connectors are different sizes. For example, if you use new radiators on old central heating systems. Use an adapter to take 15mm valves down to 10mm or 8mm. Use a reducer to bring a ¾' radiator inlet down to the standard ½' size of modern valves. With a choice of finish, including brass or chrome, you can match your adapters to your radiator to fully customise the job.
