Home > Pipe, Fittings and Sheet > Backing Rings Backing Rings Description A backing ring is a circular metal ring, with holes around the perimeter, used in pairs to bolt two HDPE pipe spools together. This allows lengths of PE pipe to be disconnected and re-connected, for inspection, replacement or relocation. The internal diameter of the backing ring should always be slightly larger than the outside diameter of the HDPE pipe. These metal backing rings allow the two ends of a pipe to be joined with bolts. Also known as back up plates, backing rings hold the pipeline tightly to a valve or fitting and are often required for high-pressure pipe applications. FHS Poly can supply galvanised or Stainless Steel backing rings.
