Nibco CN00500 Poly Pipe Adapter Coupling 1/2 in Sch 80

Product Description

The NIBCO CN00500 is a Schedule 80 polypropylene pipe adapter coupling designed to transition between socket (spigot) and female pipe thread (FPT) connections in plastic piping systems. Built from virgin polypropylene, this fitting delivers solid chemical resistance and is well-suited for demanding fluid-handling applications where corrosion is a concern. At 1/2 inch in size with Schedule 80 wall thickness, it provides greater pressure tolerance than Schedule 40 fittings of the same diameter. Plumbers and pipefitters typically install this type of adapter wherever a solvent-weld plastic line must connect to a threaded port, valve, or equipment fitting.

This adapter coupling is used in residential and light commercial plumbing, chemical distribution lines, and industrial process piping where polypropylene is specified for its resistance to acids, bases, and a broad range of corrosive fluids. The 1/2 inch sizing fits common branch and service lines. Schedule 80 construction makes it appropriate for higher-pressure service conditions compared to standard Schedule 40 plastic fittings. It ships as a single unit, making it practical for small repairs or single-point replacement installations.

Key Features

• Schedule 80 polypropylene construction for higher pressure rating than Schedule 40
• Socket (S) inlet for solvent-weld connection to polypropylene pipe
• Female pipe thread (FPT) outlet for connection to threaded valves, equipment, or fittings
• Polypropylene material offers broad chemical resistance to acids, bases, and solvents
• 1/2 inch fitting size fits standard residential and commercial service line diameters

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene piping systems using socket and female pipe thread end connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASTM standards for plastic piping systems. Shut off and depressurize the line fully before cutting into existing pipe. Use only solvent cement rated for polypropylene on the socket end, and apply thread sealant tape or compound rated for plastic threads on the FPT connection. Do not over-torque the threaded connection, as polypropylene threads can crack under excessive mechanical force.
