Description
This composite union combines the benefits of PVCu pipework and brass threaded connections to create a versatile, demountable joint suitable for imperial solvent weld systems. The plain PVCu socket end uses solvent weld jointing for a secure permanent connection with pipe, while the BSP female brass thread provides a durable, corrosion-resistant mechanical connection point for valves, pumps or other equipment.
The three-piece union design features a central nut that allows easy disassembly without cutting the pipework, making it ideal for maintenance, inspection or equipment swaps. With a smooth internal bore and a robust composite build, this fitting is well suited to water supply, irrigation, industrial process and general engineering applications.
