Nibco CD04450 Pvdf Threaded Union 2 in Sch 80 Fipt

Product Description

The NIBCO CD04450 is a 2-inch Schedule 80 PVDF threaded union designed for plastic piping systems handling corrosive or high-purity fluid applications. PVDF (polyvinylidene fluoride) offers excellent chemical resistance, making this union a reliable choice where standard PVC or CPVC fittings are not suitable. The FIPT x FIPT end connections allow the union to join two threaded pipe sections and be disassembled without cutting pipe, which is critical for systems requiring periodic maintenance or equipment removal. Licensed plumbers and industrial pipefitters are the primary installers of this fitting.

This union is used in chemical processing, industrial fluid handling, water treatment, and laboratory piping systems where PVDF material is specified for chemical compatibility or purity requirements. The Schedule 80 wall thickness provides additional pressure-bearing capacity compared to Schedule 40 fittings, making it appropriate for higher-pressure service lines. It is also used in some aggressive HVAC chemical feed and pool chemical dosing applications where PVDF is specified by the system designer.

Key Features

• PVDF construction for superior chemical resistance and high-purity fluid compatibility
• Schedule 80 rating for increased pressure and mechanical strength
• FIPT x FIPT end connections for threaded pipe assembly and disassembly
• Red color coding for quick visual identification in multi-material piping systems
• Union design allows pipe disconnection without cutting for maintenance access

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch Schedule 80 PVDF threaded piping systems with female iron pipe thread connections.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter familiar with thermoplastic piping systems. Shut off and depressurize the line and verify it is free of fluid before disassembling or installing the union. Use PTFE thread tape rated for PVDF and chemical service when making threaded connections; do not use thread sealant compounds that are incompatible with PVDF. Follow applicable plumbing codes and the pipe system designer specifications for torque and support requirements.
