Nibco CD04300 Pvdf Threaded Union 3/4 in Sch 80

Product Description

The NIBCO CD04300 is a Schedule 80 PVDF threaded union designed for 3/4 inch pipe connections in demanding fluid-handling systems. PVDF (polyvinylidene fluoride) provides excellent resistance to aggressive chemicals, UV exposure, and high-purity process fluids, making this fitting a reliable choice where standard PVC or CPVC would be inadequate. The female iron pipe thread (FIPT x FIPT) end connections on both sides allow for straightforward installation into threaded pipe systems. This union is intended for installation by licensed plumbers and pipefitters working on industrial, chemical processing, or high-purity water systems.

This fitting is suited for applications involving corrosive chemicals, ultrapure water, or environments requiring high mechanical strength in a thermoplastic fitting. Schedule 80 wall thickness provides added pressure-bearing capacity over Schedule 40 fittings. The red color coding aids in quick visual identification on the job. Typical installations include chemical feed lines, laboratory plumbing, semiconductor fabrication water systems, and industrial process piping where metal fittings are not appropriate.

Key Features

• PVDF construction offers superior chemical and UV resistance compared to standard thermoplastics
• Schedule 80 wall thickness for elevated pressure ratings in thermoplastic piping systems
• FIPT x FIPT end connections on both sides for straightforward threaded assembly
• Red color coding for quick visual identification in multi-line installations
• Union design allows pipe disconnection without cutting, simplifying maintenance and system servicing

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4 inch Schedule 80 thermoplastic threaded piping systems with FIPT end connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic pipe systems. Shut off and depressurize the line completely before disassembly or installation. Use thread sealant tape or compound rated for PVDF and the specific process fluid involved, as some sealants are incompatible with aggressive chemicals. Do not over-tighten threaded PVDF fittings, as the material can crack under excessive torque.
