Description
This composite union fitting is designed to connect solvent welded Corzan CPVC pipework to BSP male threaded components via a brass female outlet. It is particularly suited to installations where CPVC systems interface with valves, pumps or metallic equipment and where future disconnection may be required.
The plain socket end is solvent welded to CPVC pipe using PVC-C solvent cement and Eco-Cleaner, creating a strong, pressure-rated joint. The brass female BSP thread provides a durable and reliable connection point, offering improved thread engagement and mechanical strength in mixed-material assemblies.
Manufactured from high-performance Corzan CPVC with a non-toxic, taint-free formulation, the union performs reliably in hot, corrosive and potable water applications. Its demountable design supports easier maintenance and system modification, while the lightweight construction simplifies handling during installation.
