Nibco CC04750 Reducer Bushing 3/4x1/2 in Polypropylene Sch 80

Product Description

The NIBCO CC04750 is a flush socket reducer bushing manufactured from Schedule 80 polypropylene, designed to transition from a 3/4-inch to a 1/2-inch pipe connection within a plastic piping system. The SPG x S end configuration means one end is a spigot that inserts into a female socket fitting, while the other end accepts a plain-end pipe or fitting using a solvent-cement socket joint. Built from black polypropylene, this bushing resists a broad range of chemicals and is well-suited for industrial process piping, chemical handling, and corrosive-fluid applications. Plumbers and pipefitters working with thermoplastic systems install this type of fitting to reduce line size without requiring a separate coupling or union.

The CC04750 is used in residential and commercial plastic piping systems where a size reduction between 3/4-inch and 1/2-inch lines is needed at a socket fitting. It is appropriate for Schedule 80 plastic piping installations involving water service, chemical distribution, and similar fluid-handling systems. The flush socket design seats cleanly inside the receiving fitting, keeping the assembly compact and maintaining consistent flow path alignment. Polypropylene construction makes this fitting a common choice in applications where PVC or CPVC compatibility with certain chemicals or temperatures is a concern.

Key Features

• Schedule 80 wall thickness for use in higher-pressure plastic piping systems
• SPG x S end connections allow direct insertion into a female socket fitting on one end and socket cementing on the other
• Polypropylene construction provides chemical resistance suitable for corrosive-fluid handling
• Flush socket design keeps the installed profile compact within the fitting assembly
• Black color indicates polypropylene material, aiding field identification

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene plastic piping systems using SPG x S socket connections in 3/4-inch to 1/2-inch reducer applications.

Installation Notes

This fitting is installed by licensed plumbers or pipefitters working with thermoplastic Schedule 80 systems. Depressurize and drain the line completely before cutting into any existing piping. Use only solvent cement rated for polypropylene — standard PVC cement is not compatible with polypropylene and will result in a failed joint. Follow applicable plumbing codes such as the IPC for permitted applications, joint preparation, and cure times before returning the system to service.
