Nibco CC06050 Blind Pipe Flange 3 in Polypropylene Sch 80

Product Description

The NIBCO CC06050 is a Schedule 80 blind pipe flange manufactured from polypropylene and finished in black. A blind flange closes off the end of a piping run, providing a pressure-tight termination point without requiring a threaded or welded cap. With a 3-inch pipe size and a 7.5-inch outer diameter, this flange is suited for chemical drainage, industrial process lines, and corrosion-resistant plumbing systems where metal flanges would degrade. Licensed plumbers and pipefitters install this fitting in systems that handle aggressive fluids or require periodic access to a sealed line end. The polypropylene construction resists a wide range of acids, bases, and solvents at moderate temperatures.

This blind flange is used in residential and commercial plumbing systems that specify thermoplastic Schedule 80 components. Typical applications include chemical process piping, industrial drainage, and corrosive-fluid distribution where polypropylene is specified for its chemical resistance. The fitting is appropriate for above-ground and indoor installations where UV exposure and extreme temperature swings are not a primary concern. It is commonly paired with Schedule 80 polypropylene flanged piping assemblies in laboratory, manufacturing, and wastewater treatment environments.

Key Features

• Schedule 80 wall rating for higher-pressure thermoplastic piping systems
• Polypropylene construction provides broad chemical resistance to acids, bases, and solvents
• 3-inch pipe size with 7.5-inch outer diameter for standard flanged connections
• Blind design seals the end of a flanged piping run without additional fittings
• Black finish polypropylene for easy visual identification in multi-material piping systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene flanged piping systems with a 3-inch pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic flanged piping systems. Depressurize and drain the line completely before removing or installing any flange fitting. Fastener torque patterns and gasket selection should follow the piping system manufacturer guidelines and applicable IPC or ASTM standards for thermoplastic flanges. Avoid over-torquing flange bolts, as polypropylene flanges can crack under excessive clamping load.
