Variable Gibault Couplings are a fast and easy way of connecting to pipes even with differing outsie diameters or materials. They are able to join two sections of pipe with an OD variance of up to 24mm. The stainless steel body and fusion coated Ductile Iron flanges give the gibault couplings superior corrosion resistance. The convex barrel allows for angular deflection to be accommodated when joining two pipes. The use of Gibault couplings can reduce pipeline downtime and provides a permanent pipeline repair solution.
