Nibco CD04400 Threaded Union 1-1/2 in Pvdf Sch 80

Product Description

The NIBCO CD04400 is a Schedule 80 PVDF threaded union sized at 1-1/2 inches with female iron pipe thread (FIPT) connections on both ends. PVDF (polyvinylidene fluoride) is a high-purity, chemically resistant thermoplastic used in aggressive fluid handling applications where metal fittings are unsuitable. The union design allows inline disconnection of piping without cutting, making it practical for maintenance and equipment service. At 1 pound, this fitting is lightweight without sacrificing the pressure rating and chemical resistance expected from Schedule 80 PVDF components. It is installed by licensed plumbers and industrial pipefitters working on chemical process, water treatment, and high-purity fluid systems.

This union is suited for residential and commercial systems handling corrosive or high-purity fluids where PVDF is specified. Common applications include chemical dosing lines, deionized water distribution, pool and spa chemical feed systems, and industrial process piping. The FIPT x FIPT end connections thread directly onto male-threaded Schedule 80 pipe or fittings, making installation straightforward in existing threaded plastic piping systems.

Key Features

• Schedule 80 PVDF construction for high-pressure and chemical-resistant service
• 1-1/2 inch size with FIPT x FIPT end connections for threaded system integration
• Union design allows inline disconnection and reconnection without cutting pipe
• Red color for easy system identification in multi-line installations
• Lightweight at 1 pound for overhead and confined-space installations

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter familiar with thermoplastic piping systems. Shut off flow and depressurize the line before disassembly or installation. Use thread sealant rated for PVDF and the specific fluid being handled — do not use petroleum-based compounds on plastic threads. Avoid over-tightening FIPT connections, as plastic threads are susceptible to cracking under excessive torque.
