The PP Natural Stub Flange is designed to create a demountable flanged joint within inch polypropylene pipe systems. Manufactured from high-quality natural polypropylene block copolymer, this fitting allows PP pipework to be connected to valves, equipment, or other flanged components when used in conjunction with a backing ring and gasket.

Produced in accordance with BS 4991: 1974 Series 1, the stub flange is pressure rated to 10 bar and is well suited to industrial environments where chemical resistance, purity, and ease of maintenance are essential. The natural, unpigmented material makes it particularly suitable for contamination-sensitive applications.

• Flanged connection point: Enables easy dismantling for inspection or maintenance
• 10 bar pressure rating: Suitable for demanding industrial pipework systems
• Natural polypropylene (PP-B): Excellent chemical resistance and impact strength
• Smooth bore design: Helps maintain efficient flow characteristics
• Corrosion resistant: Will not rust, scale, or degrade over time
• Lightweight construction: Easier handling compared with metal alternatives
