This polypropylene threaded union is designed to join two sections of pipework while allowing quick and clean disconnection when required. It is commonly installed in areas where regular maintenance, inspection or component replacement is expected, such as around pumps, valves or equipment connections.

Manufactured from high heat stabilised polypropylene block copolymer (PP-B), the union offers excellent chemical resistance, strong impact performance and long service life in demanding industrial environments. The central union nut allows the joint to be separated without rotating the pipework, making installation and future servicing significantly easier.

As part of the threaded polypropylene system, this fitting is pressure rated to 6 bar and is intended for low pressure applications where flexibility and accessibility are key design requirements.

• Demountable joint: Allows pipe sections to be separated without cutting
• 6 bar pressure rating: Suitable for threaded PP pipe systems
• Threaded connections: Compatible with BS 4991 pipe dimensions
• PP-B construction: Improved toughness and impact resistance at low temperatures
• Wide operating temperature range: Continuous use from -20°C to 110°C
• Corrosion resistant: Will not rust, scale or degrade in aggressive media
• Lightweight fitting: Easier handling compared to metal unions
• Industrial versatility: Ideal for chemical processing, water treatment, laboratories, food production and general industrial installations
