Georg Fischer 9854-060 Cpvc Van Stone Flange 6 Inch Sch 80

Product Description

The GEORG FISCHER 9854-060 is a Schedule 80 CPVC Van Stone flange with a slip socket connection, rated for 150 psi service. Van Stone flanges feature a rotating loose ring design that allows the flange face to be positioned freely during bolt-up, reducing installation stress on piping. Built from CPVC, this flange is suited for corrosive chemical and high-temperature fluid systems where standard PVC would fall short. The 6-inch socket end joins to standard Schedule 80 CPVC pipe. Licensed plumbers and pipefitters working in industrial and commercial piping systems are the primary installers of this component.

This flange is used in industrial process piping, chemical transfer lines, water treatment systems, and corrosive fluid handling applications where thermoplastic construction is specified. The Van Stone style is a common choice in systems that require frequent disassembly for maintenance or inspection, since the loose ring allows bolt holes to align without rotating the pipe itself. Schedule 80 wall thickness provides additional pressure integrity and mechanical strength over Schedule 40 in demanding service environments.

Key Features

• Van Stone loose-ring design allows free rotation for easy bolt-hole alignment during installation
• Schedule 80 wall construction rated to 150 psi
• CPVC material handles corrosive chemicals and elevated service temperatures beyond the range of standard PVC
• 6-inch slip socket end for solvent-cement joining to Schedule 80 CPVC pipe
• Thermoplastic construction resists rust and corrosion in wet and chemical environments

Compatibility

Designed as an OEM-style thermoplastic replacement flange for 6-inch Schedule 80 CPVC piping systems requiring a 150 psi Van Stone slip flange connection.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Depressurize and drain the system completely before cutting into any existing piping. Solvent-cement joints require proper surface preparation, primer application, and cure time before returning the system to service. Torque flange bolts evenly in a cross pattern to the gasket and flange manufacturer specifications using appropriate fasteners for the service fluid.
