The PP Union Plain x Thread fitting is designed to provide a practical demountable connection between a plain-ended PPb pipe and a threaded component within a polypropylene pipework system. Incorporating a union nut, this fitting allows sections of pipework to be easily disconnected and reconnected without cutting or disturbing the surrounding installation.

Manufactured from high-quality polypropylene block copolymer (PP-B) to BS 4991 : 1974, the union offers excellent chemical resistance, strong mechanical performance and long-term reliability in industrial environments. The plain end is suitable for socket fusion to PPb pipe, while the threaded end enables straightforward connection to valves, fittings or equipment with female BSP threads.

Lightweight, corrosion-resistant and maintenance-friendly, plain x threaded PP unions are particularly useful where future access, servicing or system modification may be required.
