Nibco CC00450 3/4 in Poly Schedule 80 Pipe Coupling Fpt

Product Description

The NIBCO CC00450 is a Schedule 80 polypropylene pipe coupling designed for threaded pipe connections in industrial and commercial plumbing systems. Rated for working temperatures up to 180 degrees F, this black polypropylene fitting handles demanding service conditions where chemical resistance and durability are required. The FPT x FPT end connections accept standard female-threaded pipe on both ends, making it a direct, no-solder solution for joining or repairing threaded plastic pipe runs. Licensed plumbers and pipefitters working on corrosive-fluid or high-temperature plastic piping systems will find this coupling a code-compliant, reliable choice conforming to ASTM D4101.

This coupling is suited for Schedule 80 plastic piping systems in industrial process, commercial plumbing, and chemical handling applications. The 3/4 inch size fits standard 3/4 inch pipe, covering a common distribution and branch-line diameter. The polypropylene construction resists a wide range of acids, bases, and solvents, making this fitting appropriate for systems conveying corrosive media where metal fittings would degrade. It installs wherever a union of two female-threaded pipe ends is required without solvent cement or heat fusion.

Key Features

• Schedule 80 wall thickness provides increased pressure rating over Schedule 40 fittings
• Polypropylene construction offers chemical resistance to acids, bases, and many solvents
• FPT x FPT end connections accept standard male-threaded pipe or nipples on both ends
• Maximum working temperature of 180 degrees F suits hot-water and process-fluid service
• Black color identifies polypropylene material for quick field identification
• Conforms to ASTM D4101 for polypropylene plastic pipe fittings

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene threaded piping systems using 3/4 inch FPT connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter following applicable IPC and local code requirements. Shut off and depressurize the piping system fully before removing any existing fitting. Use PTFE thread tape or an approved thread sealant rated for plastic fittings — do not overtighten, as polypropylene threads can crack under excessive torque. Do not use solvent cements or open-flame tools on polypropylene fittings.
