Description
This 90° reducing tee fitting is designed to form a perpendicular branch from a main Corzan CPVC pipeline while stepping down to a smaller pipe size. It is commonly used where flow needs to be diverted or distributed to secondary lines without maintaining the full bore diameter.
Manufactured from high-performance Corzan CPVC, the fitting delivers excellent resistance to corrosive chemicals, elevated temperatures and pressurised conditions. Solvent welding with PVC-C solvent cement and Eco-Cleaner creates a permanent, leak-tight joint that removes the need for hot works permits and specialist installation skills.
The internal geometry of the reducing branch promotes controlled flow transition, helping limit turbulence where the bore size changes. Lightweight yet durable, this fitting forms part of a fully matched Corzan CPVC system designed for long service life, low maintenance and dependable operation in demanding industrial environments.
Key Features & Benefits
