Nibco CD03945 Pvdf Threaded Pipe Nipple Sch 80 2x3 in

Product Description

The NIBCO CD03945 is a Schedule 80 PVDF threaded pipe nipple designed for use in demanding fluid-handling systems where chemical resistance and pressure integrity are critical. Measuring 2 inches in pipe size and 3 inches in length, this nipple is molded from polyvinylidene fluoride (PVDF), a high-performance thermoplastic that withstands aggressive chemicals, elevated temperatures, and UV exposure. The red color coding aids in quick identification on the job. Licensed plumbers and pipefitters typically specify this nipple in corrosive-media piping systems where metal fittings would degrade or contaminate the process fluid.

This nipple is suited for industrial, commercial, and specialty plumbing applications involving acids, bases, solvents, and high-purity fluids. Schedule 80 wall thickness provides the pressure rating and structural rigidity needed in systems with elevated operating demands. It is commonly installed in chemical processing facilities, water treatment plants, semiconductor fabrication, and laboratory plumbing where PVDF is the material of choice.

Key Features

• PVDF construction for superior chemical resistance and long service life in corrosive environments
• Schedule 80 wall thickness for higher pressure ratings compared to Schedule 40
• 2 inches pipe size x 3 inches length for standard close-nipple configurations
• Red color coding for easy system identification and material differentiation
• Threaded ends for tool-based installation without solvent welding or heat fusion

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Schedule 80 PVDF threaded piping systems using 2-inch nominal pipe connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic threaded piping systems. Apply a PVDF-compatible thread sealant or PTFE tape — do not use pipe dopes or compounds that contain petroleum solvents, as these can degrade PVDF. Isolate and depressurize the line and verify zero pressure before making any connections. Follow applicable IPC or ASME B31.3 process piping standards for thread engagement, support spacing, and pressure testing.
