Nibco CC08970 Tank Adapter 1-1/4 in Polypropylene Sch 80

Product Description

The NIBCO CC08970 is a Schedule 80 polypropylene tank adapter designed to create a secure, threaded connection between a storage tank and a piping system. Rated for Schedule 80 service, this fitting handles higher-pressure applications where a standard Schedule 40 fitting would be undersized. The black polypropylene construction resists corrosion and chemical attack, making it suitable for water treatment, chemical storage, and plumbing systems where metal fittings would degrade. At 0.34 pounds, the fitting is lightweight and easy to handle during installation. Licensed plumbers and trade technicians are the typical installers of this component.

This tank adapter is used where a threaded pipe connection must be made directly to a tank wall in residential or commercial applications. Common installations include water softener tanks, chemical dosing tanks, pressure vessels, and irrigation storage tanks. The FPT x FPT end connections accept male-threaded pipe or fittings on both sides, allowing flexible integration into existing threaded piping runs. Its black color and polypropylene material make it appropriate for both indoor utility and outdoor environments where UV and chemical resistance are priorities.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the system fully before removing or installing any tank fittings. Use PTFE thread tape or an approved thread sealant on all male threads before assembly — do not use pipe dope compounds that are incompatible with polypropylene. Avoid over-torquing plastic fittings, as excess force can crack the fitting body or tank boss.
