Nibco CC06550 Pipe Nipple 3/4 in Schedule 80 Polypropylene

Product Description

The NIBCO CC06550 is a Schedule 80 polypropylene threaded pipe nipple designed for use in piping systems that require lightweight, corrosion-resistant plastic fittings. Sized at 3/4 inch pipe diameter and 2 inches in length, this nipple connects threaded pipe runs using male NPT threads on both ends. It handles a maximum working pressure of 20 psi and is rated for temperatures up to 180 degrees F, making it suitable for moderate-temperature fluid handling applications. The black polypropylene construction resists corrosion and many common chemicals, offering a practical alternative to metal nipples in compatible service conditions. Licensed plumbers and pipefitters are the typical installers.

This pipe nipple is suited for residential and light commercial plumbing systems where polypropylene plastic fittings are specified. Common applications include drainage tie-ins, chemical-resistant piping runs, and low-pressure water distribution segments where metal corrosion is a concern. The MNPT thread configuration allows it to thread directly into standard female NPT fittings, valves, and equipment ports. It conforms to ASTM D4101 standards for polypropylene pipe materials.

Compatibility

Designed as an OEM-style replacement or direct-install fitting for standard 3/4 inch female NPT threaded plumbing connections in Schedule 80 polypropylene piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off and depressurize the supply line before removing any existing fittings. Use PTFE thread tape or an approved thread sealant rated for use with polypropylene on all MNPT connections. Do not overtighten plastic threaded fittings, as polypropylene threads can crack under excessive torque.
