Description

The PP union plain x BSP fitting is designed to join metric polypropylene pipework to BSP threaded components while allowing the joint to be easily disconnected when required. Unlike fixed adaptors, the integrated union nut enables straightforward removal of valves, instruments or sections of pipework for maintenance or system modification.

Manufactured from polypropylene block copolymer (PP-B), this union offers excellent impact strength, chemical resistance and durability across a wide operating temperature range. The plain socket end is suitable for socket fusion welding onto PP pipe, while the BSP threaded end connects directly to standard BSP female fittings.

With a 6 bar pressure rating, this union adaptor is ideal for low-pressure industrial systems where flexibility, corrosion resistance and serviceability are important.
