Premium PVCu Stub Flange Serrated Face Plain Metric Socket with High Abrasion and Corrosion Resistance for Potable Water Systems

This premium PVCu stub flange with serrated face and plain metric socket is designed for reliable connection of PVCu pipework in pressurised systems. Engineered for durability and consistency, it provides a secure joint interface where a flanged connection is required, while maintaining excellent flow characteristics through the pipeline.

Offering high resistance to abrasion and corrosion, this stub flange is particularly suitable for potable water distribution and general industrial pipework. Its PVCu construction helps protect against chemical attack and long-term wear, making it an ideal choice for water treatment plants, process lines, and building services installations.

Product Features

• Manufactured from high-quality PVCu for excellent chemical and corrosion resistance.
• Serrated sealing face to enhance gasket grip and improve flange joint integrity.
• Plain metric socket end for solvent weld connection to matching PVCu pressure pipe.
• Available in common metric sizes including 50mm, 63mm, 75mm, 90mm and 110mm, plus additional larger and smaller options.
• Suitable for potable water systems and many other pressurised liquid applications.
• Lightweight construction for easier handling and faster on-site installation.
• Precision-moulded dimensions to ensure compatibility with standard PVCu pipe and flange drilling patterns.

Key Features and Benefits

• High abrasion resistance helps maintain long service life in systems carrying particulates or where flow velocities are higher.
• Outstanding corrosion resistance reduces the risk of leaks and failures compared with metal fittings in aggressive environments.
• Potable-water-safe PVCu material supports compliance in drinking water distribution and treatment applications.
• Plain socket solvent weld joint offers a strong, permanent connection with minimal risk of mechanical loosening.
• Serrated flange face provides improved gasket sealing performance, helping to minimise maintenance and downtime.
• Range of metric sizes makes it straightforward to integrate into new installations or retrofit to existing PVCu pipework.

Specifications

Applications and Ideal Uses

This PVCu stub flange is designed for use wherever a solvent-welded PVCu pipeline needs to be terminated or connected via a flanged joint, particularly in potable water and light industrial systems.

• Potable water distribution mains and branch lines in commercial and industrial buildings.
• Water treatment and filtration plant pipework where reliable flange connections are required.
• Process water systems in light industrial and manufacturing environments.
• Pumping stations and plant rooms requiring demountable flanged connections for maintenance.
• Irrigation and non-potable water services using PVCu pressure pipework.

Frequently Asked Questions

Is this PVCu stub flange suitable for use with drinking water?

Yes, the fitting is made from PVCu that is suitable for potable water applications when installed as part of an appropriately specified system. Always ensure the rest of the system, including pipe, gasket and seal materials, also meets potable water requirements.

How is the plain metric socket end of the stub flange connected to the pipe?

The plain metric socket is designed for solvent weld connection. The pipe and socket are cleaned and primed as required, then joined using a compatible PVCu solvent cement, forming a strong, permanent bond once cured.

Can this stub flange be used with existing flanged equipment and valves?

In most cases, yes, provided the flange drilling pattern and nominal size match the equipment or valve being connected. Always check the size and flange specifications against the mating component and use an appropriate gasket and bolt set to complete the joint.
