Our Ductile Iron Wide Range Couplers provide a high tolerance, reliable solution for joining two plain ended pipes of the same internal bore but differing outside diameters (OD). Engineered with a wider tolerance than standard couplings, these universal fittings take the stress out of on-site pipe jointing where precise pipeline matching is difficult.

Built for durability, each coupler features a robust carbon steel body paired with a heavy-duty EN-GJS-500-7 ductile iron gland. This combination offers high impact resistance and exceptional structural integrity for underground applications, water infrastructure, and civils projects.

Equipped with premium EPDM sealing gaskets and galvanised fasteners, these couplers ensure long term, leak free performance and excellent corrosion protection in damp valve chambers or buried soil conditions. They also allow for a considerable amount of angular deflection, making them highly accommodating for pipeline settlement or minor misalignments.
