Universal Flange Adapter

Universal Flange Adapter PN16 is a high-performance mechanical coupling designed to connect plain-end pipes to flanged systems with maximum flexibility. This wide tolerance adapter allows installation across a range of pipe diameters (SR1 tolerance), making it ideal for repair, maintenance, and new pipeline installations.

The body is manufactured from high-strength ductile iron, ensuring durability under pressure and mechanical stress. The sealing system features WRAS-approved EPDM gasket, providing reliable leak-tight performance for potable water and infrastructure applications.

The adapter is equipped with Sheraplex-coated steel bolts and nuts (Grade 8.8), offering superior corrosion resistance and long service life even in aggressive environments.

Suitable for PN16 pressure class systems, this universal flange adapter complies with ISO 7005-2 and ANSI B16 drilling standards, enabling compatibility with multiple flange types.
