Nibco CD04000 Pvdf Socket Union 1/2 in Schedule 80

Product Description

The NIBCO CD04000 is a 1/2 inch Schedule 80 PVDF socket union designed for joining and disconnecting plastic piping systems in demanding industrial and chemical service applications. PVDF (polyvinylidene fluoride) offers high resistance to corrosive chemicals, elevated temperatures, and UV exposure, making it a preferred material where standard PVC or CPVC would degrade. The union features a slip socket on one end and a solvent-weld or SR FIPT connection on the other, allowing technicians to break a line without cutting pipe. At 1 pound, this compact fitting is handled and installed by licensed plumbers and pipefitters working on chemical process, industrial, or high-purity water systems.

This fitting is suited for Schedule 80 PVDF piping systems in residential and commercial applications where corrosion resistance and chemical compatibility are critical. Typical install scenarios include chemical feed lines, wastewater treatment piping, semiconductor fabrication facilities, and industrial process lines. The red color coding aids in quick visual identification of PVDF lines in multi-material piping systems. End connections are Slip x SR FIPT, allowing integration with both solvent-welded and threaded PVDF components in the same system.

Key Features

• PVDF material provides excellent resistance to corrosive chemicals, UV exposure, and elevated service temperatures
• Schedule 80 wall thickness for higher pressure ratings compared to Schedule 40 fittings
• Slip x SR FIPT end connections allow connection to both solvent-welded and threaded PVDF piping
• Union design allows the line to be broken and reassembled without cutting pipe
• Red color coding for quick visual identification of PVDF piping runs
• 1/2 inch fitting size suits small-diameter process and chemical service lines

Compatibility

Designed as an OEM-style replacement or new-install fitting for Schedule 80 PVDF piping systems with 1/2 inch nominal pipe size and Slip x SR FIPT end connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with plastic piping systems and applicable codes such as the IPC and ASTM standards for PVDF solvent welding. Depressurize and drain the line completely before disassembling or installing the union. Use only PVDF-compatible solvent cement and primer on the slip socket connection; do not apply PVC or CPVC cement to PVDF fittings. Avoid over-torquing the union nut on the SR FIPT side, as PVDF threads can crack under excessive mechanical stress.
