Nibco CE04900 Pvdf Threaded Pipe Flange 1-1/2 Inch Sch 80

Product Description

The NIBCO CE04900 is a Schedule 80 PVDF threaded pipe flange designed for 1-1/2 inch pipe with a 5 inch outer diameter. Constructed from natural polyvinylidene fluoride (PVDF), this flange delivers strong chemical resistance and is well suited for aggressive fluid handling applications where metal flanges are not appropriate. The threaded connection allows for tool-accessible installation without solvent welding, making it a practical choice in maintenance-heavy systems. Licensed plumbers and industrial pipefitters typically specify Schedule 80 PVDF flanges in chemical processing, high-purity water, and corrosive fluid piping systems.

This flange is used in industrial and commercial piping systems that handle corrosive chemicals, acids, or high-purity fluids. The Schedule 80 wall thickness rating provides added pressure capability compared to Schedule 40 PVDF fittings. It is a common choice in chemical dosing lines, water treatment facilities, semiconductor fabrication facilities, and similar environments where metal corrosion or contamination is a concern. The natural finish indicates the material is unpigmented PVDF, maintaining the material's baseline chemical and thermal performance.

Key Features

• PVDF material provides excellent resistance to a wide range of acids, bases, and solvents
• Schedule 80 rated for higher pressure service compared to Schedule 40
• Threaded connection simplifies installation and future serviceability
• 1-1/2 inch pipe size with 5 inch outer diameter for standard flanged connections
• Natural PVDF finish maintains material purity for high-purity fluid applications
• Weighs 1 pound, making it lightweight relative to equivalent metal flanges

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter familiar with thermoplastic piping systems. Depressurize and drain the piping system fully before removing or installing any flange. Use appropriate thread sealants rated for PVDF and the specific process fluid — not all thread compounds are compatible with PVDF. Follow applicable plumbing codes, including IPC and local jurisdictional requirements, for pressure ratings and inspection requirements.
