Nibco CN00700 Poly Pipe Adapter Coupling 2 in Sch 80

Product Description

The NIBCO CN00700 is a 2-inch Schedule 80 polypropylene pipe adapter coupling designed for joining plain-end pipe to female threaded connections in chemical, industrial, and plumbing piping systems. Constructed from polypropylene, this fitting offers solid resistance to a wide range of corrosive fluids and is well-suited for applications where metal fittings would be vulnerable to chemical attack. The spigot by female pipe thread (S x FPT) end configuration allows direct transition from a smooth pipe end to a threaded port. At 0.34 pounds, it is lightweight without sacrificing the structural integrity required for Schedule 80 pressure ratings. Licensed plumbers and industrial pipefitters are the primary installers.

This adapter coupling is used in residential and commercial plumbing, chemical processing lines, irrigation systems, and industrial fluid-handling applications where Schedule 80 polypropylene piping is specified. The 2-inch size fits standard 2-inch pipe runs and is commonly installed at pump inlets, tank connections, or any transition point between plain-end polypropylene pipe and a threaded fitting or valve. It is sold individually and is appropriate for new construction and retrofit work alike.

Key Features

• Schedule 80 wall thickness rated for higher pressure service compared to Schedule 40 fittings
• Polypropylene construction provides resistance to a broad range of acids, bases, and chemical solutions
• S x FPT end connections allow transition from plain pipe end to female-threaded port in a single fitting
• 2-inch fitting size suits standard residential and commercial piping runs
• Lightweight at 0.34 pounds, reducing load on fittings and supports

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 polypropylene piping systems using 2-inch nominal pipe size with S x FPT end connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable local plumbing codes. Depressurize and drain the line completely before removing any existing fittings or making connections. Solvent cement compatible with polypropylene must be used on the spigot end; do not use standard PVC or CPVC cement. Ensure female threaded connections are properly cleaned and wrapped with thread sealant tape rated for polypropylene piping service.
