Description
This PVCu imperial x metric union is designed to join pipework of two different sizing systems, providing a secure transition between imperial PVCu pipe and metric PVCu pipe. Its three-piece construction features solvent-weld sockets on both ends, with a central union nut that allows the joint to be easily dismantled for maintenance, equipment servicing or system adjustments.
Constructed from corrosion-resistant PVCu, the fitting offers long service life and dependable performance across water systems, industrial processing and general engineering. The smooth internal bore supports efficient flow across the size transition when used with PVCu solvent cement, making it suitable for installations where mixed standards need to be integrated quickly and cleanly.
