Description
This premium PVCu blanking flange is designed to provide a secure, pressure-rated termination point on pipeline runs, pump manifolds and valve assemblies. Drilled to BS4504 NP10-16, it offers reliable performance in potable water systems and compatible process lines where safety, cleanliness and integrity are critical.
Manufactured from high-quality unplasticised PVC (PVCu), this flange combines excellent chemical resistance with a smooth, non-tainting internal surface suitable for drinking water applications. Available in a wide range of sizes from 20mm, 25mm, 32mm, 40mm, 50mm and more, it is ideal for water treatment, industrial, agricultural and general services pipework.
Product Features
- Premium PVCu blanking flange drilled to BS4504 NP10-16 bolt patterns for assured compatibility with standard pipework systems.
- Suitable for nominal pipe sizes starting from 20mm, 25mm, 32mm, 40mm and 50mm, plus additional larger diameters for broader installation requirements.
- Designed for use in potable (drinking) water systems with a non-toxic, non-tainting PVCu material construction.
- High-performance chemical resistance, making it suitable for many treatment chemicals and industrial media within stated compatibility limits.
- Rigid, corrosion-resistant PVCu body that does not rust, pit or scale, ensuring a long service life in wet or humid environments.
- Flat-faced flange design for use with appropriate gaskets and standard bolting to achieve a secure, leak-tight blank end.
- Compatible with matching PVCu flanges, stub flanges and backing rings commonly used in pressure pipework assemblies.
Key Features and Benefits
- Secure system isolation: Provides a safe, positive seal at the end of a line or on unused branch connections, helping to prevent leaks and product loss.
- Drinking water suitability: PVCu material formulation is suitable for potable water duty, supporting compliance in water supply and treatment installations.
- Excellent chemical resistance: Performs reliably with many acids, alkalis and water treatment chemicals, reducing risk of degradation compared with metal fittings.
- Corrosion-free performance: Unlike metal flanges, PVCu is immune to rust and electrolytic corrosion, lowering maintenance needs in aggressive or damp conditions.
- Lightweight and easy to handle: Low component weight makes lifting, alignment and installation simpler, particularly on overhead or confined runs.
- Cost-effective long-term solution: Durable construction, minimal upkeep and resistance to scale build-up contribute to reduced lifecycle costs.

Frequently Asked Questions
Can this PVCu blanking flange be used in all drinking water applications?
The flange is made from PVCu suitable for potable water service and is generally appropriate for most drinking water systems when installed correctly. Always ensure the complete system, including gaskets and any associated fittings, meets the relevant standards and local regulations for potable water use.
Is the flange supplied with bolts and a gasket?
Typically, the blanking flange is supplied as a standalone component without bolts, nuts or gaskets, so these should be ordered separately to match the flange size and BS4504 NP10-16 drilling pattern. Check the specific product listing or order confirmation to see what is included.
Can this flange be used with chemicals as well as water?
The PVCu construction offers good resistance to many common chemicals, making it suitable for certain chemical dosing and treatment applications. However, chemical compatibility must always be checked against the particular media, temperature and concentration before use, and advice should be sought if there is any doubt.
