Universal Tolerance AVANNTO AOFT01 universal flange adaptors are solution to most pipe connections. With up to 29 tolerances on the pipe OD it not only eases installation but also reduce the expensive and time-consuming trial holes, reduce stock holding and increase stock turn over. 3.

Description: -Wide tolerance range: an average of 29mm. -Small number of models for a Nominal Diameter. -High performance: Permanent leak tight joint when compressing the gasket between the end ring and the sleeve onto the pipe. Anticorrosion protection: epoxy powder coating (250 μm) and Geomet 500® Gr. B for the bolts. -Ease and speed of installation: -Angular deflection ±6°. -Accommodates misalignment. -Absorbs expansion and contraction. -Important setting gap. Conformity to standards: -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. - EN 1092-2: Flanges and their joints.Part 2: Cast iron flanges. - ISO 2531: Ductile iron pipes, fittings, and accessories and their joints for water applications. - ISO 7005-2: Metallic flanges and cast iron flanges. - ISO 7483: Dimensions of gaskets for use with flanges to ISO 7005 Approval:- Drinking water approved. Note: - This coupling does not resist to longitudinal forces and pipe pullout will occur. Ensure adequate restraint is provided. - Not recommended for PE pipes Technical data Range: DN 40 to 600.
