Product Details

CPVC socket flange features an integral socket for solvent cement welding, enabling a pipe to be directly inserted and fused to the flange body. It is suitable for use in residential and light commercial fire sprinkler systems.
Made from chlorinated polyvinyl chloride (CPVC), it is inherently flame‑retardant, corrosion‑resistant, and lightweight.
This design provides high strength and rapid installation, making it ideal for creating serviceable termination points or connections to valves and equipment.
