Nibco CC08975 Tank Adapter 1-1/2 in Polypropylene Sch 80

Product Description

The NIBCO CC08975 is a Schedule 80 polypropylene tank adapter fitting sized at 1-1/2 inches with FPT x FPT end connections. It is designed to create a secure, threaded transition between a tank outlet or bulkhead and a female-threaded pipe or fitting. The black polypropylene construction resists corrosion and chemical attack, making this adapter well-suited for water treatment, chemical storage, and industrial fluid handling systems. At 0.31 pounds, it is lightweight and easy to handle. Licensed plumbers and pipe fitters are the primary installers for this type of Schedule 80 plastic fitting.

This tank adapter is appropriate for residential and light commercial applications where a threaded connection to a storage tank, pressure vessel, or containment system is required. Common installation scenarios include water softener tanks, chemical dosing tanks, and irrigation supply vessels. The FPT x FPT configuration allows direct engagement with male-threaded pipe nipples or tank spud fittings on both sides of the adapter. Its Schedule 80 wall thickness provides greater pressure capability and impact resistance compared to Schedule 40 equivalents.

Key Features

• Schedule 80 polypropylene construction for enhanced pressure rating and chemical resistance
• FPT x FPT end connections for straightforward threaded assembly
• 1-1/2 inch fitting size compatible with standard pipe sizing
• Black color polypropylene resists UV degradation and common industrial chemicals

Compatibility

Designed as an OEM-style replacement or new-installation tank adapter for Schedule 80 polypropylene piping systems with 1-1/2 inch FPT threaded connections on storage tanks, pressure vessels, or chemical containment equipment.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipe fitter in accordance with applicable IPC and local plumbing codes. Depressurize and drain the tank completely before removing or installing any threaded fittings. Use PTFE thread sealant tape rated for plastic fittings and do not over-torque, as polypropylene threads can crack under excessive force. Inspect threads on both the fitting and the tank spud for damage before assembly.
