Technical Information
Application
Molded CLASS 150 Flange fittings are coupling devices designed for joining IPS (Iron Pipe Size) plastic piping systems, where frequent
disassembly may be required, and can be used as a transitional fitting for joining plastic to metal piping systems. Suitability of application
is at the discretion of the user.
Pressure Rating
150 psi, water at 73°F.
Flange Types
One Piece — Available in socket configuration, sizes 1/2" through 8"; threaded and SR threaded (Special Reinforced) configuration
sizes 1/2" through 4".
Van Stone Style — Two-piece design with rotating flange ring, available in socket configurations, sizes 1/2" through 16"; threaded
configurations, sizes 1/2" through 4" and spigot configurations, sizes 1/2" through 12".
