Nibco CD04750 Pvdf Threaded Pipe Flange 1/2 in Schedule 80

Product Description

The NIBCO CD04750 is a PVDF threaded pipe flange designed for Schedule 80 piping systems. It features a 1/2-inch pipe size with a 3-1/2-inch outer diameter. PVDF (polyvinylidene fluoride) construction provides strong resistance to corrosive chemicals, UV exposure, and high-purity fluid applications. This flange creates a secure, removable connection point in a piping run, allowing for equipment isolation, maintenance access, or system sectioning. It is installed by licensed plumbers and pipefitters working on industrial, chemical process, or high-purity water systems where metal flanges are not suitable.

This flange is suited for use in corrosive fluid handling, chemical distribution, semiconductor fabrication water systems, and similar applications where standard metal or PVC components are inadequate. The threaded connection style makes it compatible with Schedule 80 threaded pipe and fittings. It is commonly installed in both new construction and retrofit situations requiring a chemically resistant flange at a 1/2-inch pipe junction.

Key Features

• PVDF material offers excellent resistance to acids, bases, and solvents
• Threaded connection for use with Schedule 80 pipe and fittings
• 1/2-inch pipe size with 3-1/2-inch outer diameter
• Schedule 80 pressure rating for demanding service conditions
• Lightweight at 1 pound, reducing load on pipe supports
• Suitable for high-purity and corrosive fluid applications where metal flanges are not appropriate

Compatibility

Designed as an OEM-style replacement or new-installation flange for 1/2-inch Schedule 80 PVDF threaded piping systems.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or local plumbing code requirements. Depressurize and drain the piping system fully before removing or installing any flange. Use appropriate thread sealant rated for PVDF and the specific fluid being conveyed. Do not overtighten threaded connections, as PVDF is susceptible to stress cracking from excessive torque.
