Overview
The Fernco SC425 400-425 mm shear banded coupling is designed to connect or repair low-pressure pipelines such as sewer, stormwater, and wastewater systems. The coupling is suitable for pipes with an outer diameter range of 400-425 mm. When compared with standard rubber pipe joiners, the shear banded coupling incorporates an additional reinforced stainless steel shear band positioned at the centre.
The Fernco shear banded coupling is made from flexible EPDM rubber or nitrile rubber and fitted with 316 grade stainless steel clamps, ensuring durability, elasticity, and stable long-term performance. The shear band helps protect the joint against corrosive environments, reduces the impact of shear forces caused by vibration, soil movement, or surface loading, and assists in maintaining consistent flow alignment inside the pipeline.
The Fernco SC shear banded coupling range is WaterMark licensed for use in Australia and can be used with compatible rubber bushes (sold separately) when connecting dissimilar pipe materials.
