Nibco CD03920 Pvdf Threaded Pipe Nipple Sch 80 1-1/2x4 in

Product Description

The NIBCO CD03920 is a Schedule 80 PVDF threaded pipe nipple designed for demanding fluid-handling applications where chemical resistance and pressure performance are critical. Measuring 1-1/2 inches in pipe diameter and 4 inches in length, this nipple is molded from polyvinylidene fluoride (PVDF), a high-performance thermoplastic that resists a broad range of aggressive chemicals, UV exposure, and elevated temperatures. The Schedule 80 wall thickness provides greater pressure capacity compared to Schedule 40. Licensed plumbers and industrial pipefitters install this component as a close-coupled connector between threaded fittings, valves, and equipment in corrosive-service piping systems.

This nipple is suited for use in chemical processing, water treatment, semiconductor fabrication, and industrial plumbing systems where standard metal or PVC components are inadequate. The red color coding aids in quick visual identification of PVDF lines in multi-service installations. It is appropriate for both above-ground and in-structure applications where chemical compatibility with PVDF is confirmed. Typical install scenarios include connecting pumps to distribution headers, joining valves in chemical feed lines, and extending threaded runs in corrosive-fluid systems.

Key Features

• PVDF construction provides superior chemical resistance compared to PVC or CPVC
• Schedule 80 wall thickness for higher pressure ratings in threaded plastic pipe systems
• 1-1/2 inches pipe size with 4 inches face-to-face length for close-coupled connections
• Red color coding supports visual line identification in multi-service piping layouts
• Threaded ends for direct connection to standard NPT fittings and threaded valves

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 80 PVDF threaded piping systems using 1-1/2 inch NPT connections.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter in accordance with applicable plumbing codes such as the IPC. Isolate and depressurize the system and verify that all fluid has been drained before removing or installing threaded plastic nipples. Use strap wrenches rated for plastic pipe to avoid cracking the fitting body — do not use metal pipe wrenches directly on PVDF. Apply a PVDF-compatible thread sealant or PTFE tape; avoid solvent-based compounds that may attack the material.
