Nibco CC08450 Polypropylene Socket Union 1/2 in Sch 80

Product Description

The NIBCO CC08450 is a Schedule 80 polypropylene socket union designed for 1/2 inch pipe systems requiring a reliable, removable threaded connection. Built from black polypropylene, this union delivers chemical resistance and durability well-suited to industrial and corrosive-fluid plumbing applications. The slip by SR FIPT end configuration allows one socket-style solvent-weld inlet and one female iron pipe thread outlet, giving installers flexibility when transitioning between plastic pipe and threaded fittings. Weighing just 0.11 pounds, it is a lightweight component that handles demanding service conditions where metal fittings would corrode or add unnecessary weight.

This union is intended for use in Schedule 80 plastic piping systems handling chemicals, acids, or other fluids incompatible with metal or PVC fittings. Typical applications include industrial process lines, chemical feed systems, water treatment installations, and commercial plumbing where polypropylene is specified for its thermal and chemical resistance. It allows sections of pipe to be disconnected and reconnected without cutting, making it a practical choice for pump connections, filter housings, and service access points.

Key Features

• Schedule 80 wall thickness for higher pressure ratings compared to Schedule 40
• Polypropylene construction resists a broad range of acids, bases, and chemical solutions
• Slip x SR FIPT end connections support solvent-weld-to-threaded transitions
• Black color indicates polypropylene material for easy field identification
• Union design allows in-line disconnection without cutting pipe
• Lightweight at 0.11 pounds — reduces load on pipe hangers and support structures

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2 inch Schedule 80 polypropylene piping systems using slip and female iron pipe thread connections.

Installation Notes

Installation should be performed by a licensed plumber familiar with plastic piping systems and applicable IPC or local plumbing codes. Depressurize and drain the line completely before disassembling or installing any union fitting. Use only solvents and primers rated for polypropylene when making solvent-weld connections on the slip end; standard PVC cement is not compatible with polypropylene. Hand-tighten the union nut first, then apply minimal additional torque to avoid cracking the fitting body.
