Description
This composite union combines PVCu pipework compatibility with a robust brass threaded connection to create a versatile demountable joint for imperial solvent weld systems. The plain PVCu socket end uses solvent weld jointing to form a secure permanent connection with pipework, while the brass BSP male thread provides a durable mechanical attachment point for valves, pumps or other threaded components.
The three-piece union design features a central nut that allows the joint to be dismantled quickly and easily without cutting into the pipe, making it perfect for maintenance, inspection or equipment replacement. With a smooth internal bore and a sturdy composite build, this fitting is suitable for water supply, irrigation, industrial processing and general engineering tasks.
