Nibco CC04900 Reducer Bushing 1-1/2x1 in Sch 80 Polypropylene

Product Description

The NIBCO CC04900 is a Schedule 80 flush socket reducer bushing designed to transition between 1-1/2-inch and 1-inch pipe in plastic piping systems. Molded from black polypropylene, this bushing offers solid chemical and corrosion resistance suited to industrial and commercial plumbing, chemical handling, and process piping applications. The SPG x S (spigot by socket) end connection allows it to seat flush inside a fitting socket, maintaining a clean, low-profile transition. Licensed plumbers and pipefitters install this type of reducer bushing when a branch or secondary line needs to step down in size without adding an extra coupling or offset in the run.

This bushing is appropriate for Schedule 80 polypropylene piping systems where a reduction from 1-1/2 inches to 1 inch is required in-line or at a fitting. Typical installations include chemical feed lines, industrial process systems, irrigation sub-mains, and commercial plumbing where polypropylene is specified for its resistance to acids, bases, and elevated service temperatures. The black color is standard for Schedule 80 polypropylene fittings and is not an indication of UV rating.

Key Features

• Schedule 80 wall thickness for higher-pressure service compared to Schedule 40
• Polypropylene construction provides broad chemical resistance to acids, alkalis, and many solvents
• Flush socket (SPG x S) ends allow the bushing to insert directly into a standard socket fitting without creating a step-out profile
• Black polypropylene color is standard for Schedule 80 fittings
• 1-1/2 x 1 inch size reduces from 1-1/2-inch to 1-inch socket connections in a single fitting

Compatibility

Designed as an OEM-style replacement or new-install fitting for Schedule 80 polypropylene socket-weld piping systems requiring a 1-1/2-inch to 1-inch reduction with SPG x S end connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter familiar with plastic pipe solvent-cement or socket-fusion procedures as applicable to polypropylene systems. Depressurize and drain the line fully before cutting or disassembling existing pipe. Follow the pipe and fitting manufacturer solvent-cement or fusion guidelines along with applicable IPC and local plumbing code requirements. Do not over-ream or force-fit the spigot end, as polypropylene fittings are not designed for mechanical interference correction after molding.
