We stock three different types of 90 degree connector. Each connector connects a tube at 90 degrees. We can supply either a 90 degree acute connector, a 90 degree radiused connector or a 90 degree sweeping connector. Each connector can join a tube at 90 degrees that is either 42mm in diameter (with either a 2mm or 2.6mm wall) or 48mm in diameter (with either a 2mm or 2.6mm wall).
