Nibco CC09450 Threaded Pipe Flange 3/4 in Schedule 80

Product Description

The NIBCO CC09450 is a Schedule 80 threaded pipe flange manufactured from black polypropylene, designed for use in corrosion-resistant piping systems where chemical compatibility and lightweight construction are priorities. It fits 0.75 inch nominal pipe size and measures 3.875 inches in outer diameter. The flange provides a secure, threaded connection point for joining pipe sections to pumps, valves, equipment, or system terminations. Plumbers and pipefitters install this component in industrial, commercial, and process piping applications where standard metal flanges would be subject to chemical attack or where a non-metallic system is specified.

The CC09450 is suited for Schedule 80 polypropylene piping systems handling corrosive fluids, chemicals, or deionized water. Typical installations include chemical processing lines, water treatment facilities, plating operations, and laboratory or industrial process piping where threaded polypropylene fittings are the specified connection method. Its black polypropylene construction makes it appropriate for systems requiring UV resistance or chemical inertness at the flange joint.

Key Features

• Schedule 80 wall rating for increased pressure capability in polypropylene piping systems
• Threaded connection for tool-accessible installation without solvent cementing at the flange
• Black polypropylene material resists a broad range of acids, bases, and chemicals
• 0.75 inch nominal pipe size with 3.875 inch outer diameter for standard flange bolt patterns
• Lightweight construction at 0.18 pounds reduces load on connected piping

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 80 polypropylene threaded piping systems using 0.75 inch nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic piping systems. Isolate and depressurize the line completely before disassembling any flange joint. Use appropriate thread sealant rated for polypropylene and the conveyed fluid — do not use petroleum-based compounds that can degrade polypropylene. Follow applicable IPC and local plumbing code requirements for flange bolt torque and gasket selection on thermoplastic systems.
