CPVC blind flange is a solid disc that provides a reliable closure point while allowing for future system inspection or maintenance. 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.
It is designed to bolt to a mating CPVC flange or adapter, ensuring a pressure-tight seal for straightforward installation and removal.
