Universal coupling Enables the mechanical jointing of pipes made of different materials and of various outside diameters Description Wide outside diameter range: an average of 29 mm. High performance - Permanent leak tight joint when compressing the gasket between the end ring and the sleeve onto the pipe surface - Epoxy powder coating (250 μm) and Geomet® 500 Gr. B for the bolts. Ease and speed of installation: - Angular deflection ± 5° by side. - Absorbs expansion and contraction. - Accommodates misalignment. - Important setting gap. Conformity to standards - EN 14525 : Ductile iron wide tolerance couplings and flange adaptors for use with pipes of different materials: ductile iron, Grey iron, Steel, PVC-U, PE, Fiber-cement. - NF A 48-830: Foundry products - Spheroidal graphite cast iron fittings for PVC drinking water pipes under pressure, - EN 545: Ductile iron pipes, fittings, accessories and their joints for water pipelines - requirements and test methods, - ISO 2531: Ductile iron pipes, fittings, and accessories and their joints for water applications. Approval:- Drinking water approved (WRAS). Note: - This coupling does not resist to longitudinal forces and pipe pullout will occur. Ensure adequate restraint is provided. - Not recommended for PE pipes.
