Description
This reinforced 90° tee BSP fitting is designed to create a perpendicular branch from a Corzan CPVC pipeline while providing a robust threaded outlet for connection to valves, instruments or metal pipework. The moulded reinforced ring strengthens the BSP branch, improving resistance to mechanical load and helping maintain long-term joint integrity under pressure and elevated temperatures.
Manufactured from high-performance Corzan CPVC, the fitting performs reliably in aggressive environments involving corrosive chemicals, effluent and hot process fluids. Its non-toxic, taint-free formulation also makes it suitable for potable water systems, with no risk of contamination migrating into the media.
Installation is straightforward, with the plain ends solvent welded to CPVC pipe using PVC-C solvent cement and Eco-Cleaner. This delivers a permanent, leak-tight joint without the need for hot works permits or specialist welding equipment. Internally, the smooth bore and balanced branch geometry help support controlled flow distribution while minimising pressure loss.
