Description
These metric stub flanges are designed to form a strong, permanent transition between solvent-welded PVCu pipework and bolted flange connections. Once solvent-welded onto the pipe, the stub flange is used in conjunction with a backing ring to create a secure flanged joint suitable for valves, fittings or face-to-face flange connections.
Manufactured from high-quality PVCu, they offer excellent resistance to corrosion, scaling and chemical attack, making them well-suited to potable water and general industrial applications. The serrated flange face helps maintain gasket alignment during assembly, supporting reliable sealing performance when installed correctly with solvent cement and cleaner.
