Nibco CD00300 Pvdf Pipe Coupling 3/4 in Sch 80

Product Description

The NIBCO CD00300 is a Schedule 80 PVDF pipe coupling designed for joining 3/4-inch piping systems with female iron pipe thread (FIPT) connections on both ends. PVDF (polyvinylidene fluoride) is a high-performance thermoplastic chosen for its resistance to aggressive chemicals, UV exposure, and elevated temperatures, making it a reliable choice where metal fittings are unsuitable. This coupling is identified by its red color, which is standard for PVDF Schedule 80 fittings, helping technicians distinguish material type at a glance during installation. Plumbers and pipefitters working on chemical process, industrial, or high-purity water systems commonly install this fitting.

This coupling is suited for residential and commercial piping applications where chemical resistance or corrosion resistance is a priority. Typical install scenarios include chemical feed lines, deionized or ultrapure water systems, and plumbing runs where aggressive fluids would degrade metal or standard PVC fittings. The FIPT x FIPT end connections allow threading onto male-threaded pipe or fittings on both sides, making it straightforward to integrate into existing threaded Schedule 80 systems.

Key Features

• PVDF construction provides superior chemical and UV resistance compared to PVC or CPVC
• Schedule 80 wall thickness for higher pressure ratings in demanding service conditions
• FIPT x FIPT end connections for threaded installation on both ends
• Red color coding identifies PVDF material for quick visual confirmation on the job
• 3/4-inch fitting size fits standard 3/4-inch Schedule 80 threaded pipe

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter familiar with thermoplastic threaded fittings. Shut off and depressurize the affected line before removing any existing fittings. Use PTFE thread tape rated for use with PVDF when making up threaded joints; do not use pipe dope compounds unless confirmed compatible with PVDF. Avoid over-torquing PVDF threads, as thermoplastics are more susceptible to thread damage than metal fittings.
