PVC stub flanges are designed for use in combination with PVC backing rings or metal backing rings and stub gaskets or full face gaskets. Using stubs and backing rings, rather than full face flanges makes assembly of a pipe system much simpler as the bolt holes of the flange do not have to match up when solvent cementing parts together. After assembly, the flange ring can be spun round to align holes. Our PVC plain stub flanges have a pressure rating of greater than 10bar and are fully WRAS approved for use with drinking water.
