Nibco CE04450 Pvdf Threaded Union 2 in Sch 80

Product Description

The NIBCO CE04450 is a 2-inch Schedule 80 PVDF threaded union designed for demanding industrial and chemical piping systems. PVDF (polyvinylidene fluoride) offers superior resistance to corrosive chemicals, UV exposure, and elevated temperatures, making this union a reliable choice where standard PVC or CPVC fittings fall short. The FIPT x FIPT end connections allow straightforward threaded installation into existing Schedule 80 plastic pipe systems. Licensed plumbers and industrial pipefitters install this fitting when system maintenance or future disassembly access is required at a fixed pipe joint.

This union is suited for residential and commercial chemical feed lines, water treatment systems, industrial process piping, and pool or aquatics applications where corrosive sanitizers or acids are present. The Schedule 80 wall thickness provides additional pressure rating and mechanical strength compared to Schedule 40 equivalents. It is commonly installed in systems handling chlorine, acids, and other aggressive media where metal fittings would corrode or contaminate the process fluid.

Key Features

• PVDF construction provides excellent resistance to a broad range of corrosive chemicals and UV degradation
• Schedule 80 rating delivers higher pressure capacity than Schedule 40 equivalents
• FIPT x FIPT end connections for threaded installation into Schedule 80 plastic pipe systems
• Union design allows the pipeline to be disconnected and reassembled without cutting pipe
• 2-inch fitting size accommodates standard 2-inch nominal pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch Schedule 80 PVDF plastic pipe 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. Depressurize and drain the line completely before removing or installing any union. Use PTFE thread sealant tape rated for PVDF and chemical service — do not use petroleum-based pipe dopes, which can degrade PVDF. Follow local plumbing code requirements and the pipe manufacturer torque guidelines for plastic threaded fittings to avoid cracking the fitting body.
