Nibco CC08500 Polypropylene Socket Union 3/4 in Sch 80

Product Description

The NIBCO CC08500 is a 3/4-inch Schedule 80 polypropylene socket union designed for joining and disconnecting plastic pipe systems without cutting. It provides a removable, pressure-rated connection point in lines handling corrosive or chemical-resistant piping applications. The union features a slip inlet on one side and a solvent-ring female iron pipe thread (SR FIPT) on the other, allowing connection to both socket-welded and threaded fittings. Manufactured in black polypropylene, it is suited for systems where chemical resistance and durability under moderate pressure are required. Plumbers and industrial pipe fitters install this fitting in chemical drain, vent, and process piping systems.

This union is appropriate for residential and light commercial plumbing systems as well as industrial process lines where polypropylene is the specified pipe material. Schedule 80 wall thickness provides additional pressure capacity compared to Schedule 40, making it a common choice for higher-demand applications. The Slip x SR FIPT end configuration suits installations that combine socket-welded polypropylene runs with threaded transition points, simplifying system serviceability at maintenance access locations.

Key Features

• Schedule 80 polypropylene construction for enhanced pressure ratings and chemical resistance
• 3/4-inch fitting size for standard trade pipe sizing
• Slip x SR FIPT end connections allow socket-weld to threaded transitions
• Black color provides UV resistance for exposed or semi-exposed installations
• Union design enables in-line disconnection without cutting pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene pipe systems using 3/4-inch socket and female iron pipe thread connections.

Installation Notes

Installation should be performed by a licensed plumber familiar with plastic pipe solvent-welding and threaded connection procedures. Depressurize and drain the system completely before removing or installing any union fitting. Use appropriate polypropylene-compatible solvent cement on the slip side and apply thread sealant rated for plastic fittings on the SR FIPT connection. Follow local plumbing codes and IPC guidelines for plastic piping systems.
