Nibco CE03946 Pvdf Threaded Pipe Nipple Sch 80 2x4 in

Product Description

The NIBCO CE03946 is a Schedule 80 PVDF threaded pipe nipple designed for demanding fluid handling applications where chemical resistance and pressure integrity are critical. Measuring 2 inches in pipe size and 4 inches in length, this nipple is manufactured from polyvinylidene fluoride (PVDF), a high-performance thermoplastic that resists a broad range of aggressive chemicals, UV exposure, and elevated temperatures. The natural finish indicates uncolored, virgin PVDF material. Licensed plumbers and industrial pipefitters install these nipples as connecting sections between threaded fittings, valves, and equipment in chemical process, ultrapure water, and industrial piping systems.

This nipple is suited for corrosive fluid service in both commercial and industrial environments. Common applications include chemical feed lines, semiconductor fabrication water systems, laboratory piping, and wastewater treatment facilities where metal or standard PVC components would degrade. Schedule 80 wall thickness provides increased pressure ratings compared to Schedule 40, making it appropriate for moderate-pressure service lines. It is typically installed by licensed plumbers or industrial pipefitters working on thermoplastic piping systems.

Key Features

• PVDF construction offers broad chemical resistance including acids, bases, and solvents
• Schedule 80 wall thickness delivers higher pressure capacity than Schedule 40
• Threaded ends allow tool-free dry-fit alignment before final makeup
• Natural color indicates virgin, uncolored PVDF material
• 4 inch length suits standard close-coupled fitting installations

Compatibility

Designed as an OEM-style replacement or new-installation component for Schedule 80 PVDF threaded piping systems using standard NPT fittings and valves in chemical or high-purity water service.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter familiar with thermoplastic piping systems and applicable IPC or local plumbing codes. Depressurize and drain the line completely before removing or installing any threaded nipple. Use PTFE thread tape rated for PVDF and chemical service — do not use petroleum-based pipe dopes, which can attack PVDF. Avoid over-torquing threaded connections, as PVDF threads can crack under excessive force.
