These elbows consist of four aluminium shells assembled to give either a 45° or 90° watertight fitting. 90° Has the option of a flange fitted, for direct connection to the boiler outlet and the option of test points for flue gas analysis. 45° Only available without the flange and test points.
The external diameter of both the elbows is 95mm; therefore a rubber seal is used to connect to a concentric tube.
Both are available painted or unpainted.
