Nibco CC08965 Polypropylene Tank Adapter 1 in Sch 80

Product Description

The NIBCO CC08965 is a 1-inch Schedule 80 polypropylene tank adapter designed to create a secure, leak-resistant transition between a tank fitting and a threaded pipe system. Molded from black polypropylene, this adapter handles the chemical exposure and mechanical stress common in water treatment, chemical storage, and industrial piping applications. The female pipe thread on both ends allows it to thread directly onto tank outlets and standard NPT pipe without additional fittings. Licensed plumbers and industrial maintenance technicians are the typical installers. Schedule 80 wall thickness provides added pressure and impact resistance compared to Schedule 40 fittings.

This tank adapter is suited for residential and light commercial applications where a polypropylene fitting is required for corrosion resistance or chemical compatibility. Common install scenarios include well water systems, chemical feed tanks, storage tanks, and irrigation manifolds. The FPT x FPT configuration makes it straightforward to connect existing threaded pipe runs directly to a threaded tank port. It weighs 0.38 pounds and ships as a single unit.

Key Features

• Schedule 80 wall thickness for increased pressure and impact resistance
• Polypropylene construction resists corrosion, chemicals, and moisture
• FPT x FPT end connections thread onto standard NPT pipe and tank fittings
• Black color finish typical of Schedule 80 polypropylene fittings
• Compact single-unit fitting — no additional adapters required for most tank connections

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch Schedule 80 polypropylene piping systems with standard NPT threaded connections.

Installation Notes

Installation is typically performed by a licensed plumber or qualified pipefitter. Depressurize and drain the system completely before removing or installing any threaded fittings. Use thread sealant tape or compound rated for polypropylene and the fluid being conveyed — do not over-torque, as polypropylene threads can crack under excessive force. Follow applicable IPC or local plumbing code requirements for plastic fitting installations.
