Nibco CE03500 Pvdf Blind Pipe Flange 1/2 in Schedule 80

Product Description

The NIBCO CE03500 is a Schedule 80 blind pipe flange manufactured from PVDF (polyvinylidene fluoride), a high-performance thermoplastic well suited for demanding chemical and industrial fluid handling applications. A blind flange seals the end of a piping run without the use of a threaded plug or cap, making it a standard solution for system terminations, pressure testing, and future expansion points. Rated for 1/2 inch pipe with a 3.5 inch outer diameter, this flange ships in natural PVDF finish and weighs 1 pound. It is typically installed by licensed plumbers and industrial pipefitters working on corrosive fluid systems.

This blind flange is suited for Schedule 80 thermoplastic piping systems in commercial, industrial, and chemical process environments. PVDF material makes it appropriate for applications involving aggressive chemicals, high-purity fluid handling, and settings where standard PVC or CPVC would not provide adequate resistance. Common install scenarios include chemical distribution lines, semiconductor fab utilities, water treatment systems, and industrial process piping where end-of-line closures are required.

Key Features

• PVDF construction offers excellent chemical resistance and maintains dimensional stability across a wide temperature range
• Schedule 80 pressure rating provides greater wall thickness and higher pressure tolerance than Schedule 40
• Blind flange design permanently or temporarily seals pipe ends without threaded fittings
• Natural PVDF finish with no added colorants, suitable for high-purity applications
• 1/2 inch pipe size with 3.5 inch OD for standard flange bolt-pattern alignment

Compatibility

Designed as an OEM-style replacement and standard fitting for Schedule 80 PVDF thermoplastic piping systems using 1/2 inch pipe diameter flanged connections.

Installation Notes

Installation of plastic flanges 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 flange. Follow applicable codes including ASME B31.3 for process piping when torquing flange bolts — use hand-tight plus incremental cross-pattern tightening to avoid cracking the flange face; do not use impact tools on PVDF flanges. Consult the system design specifications for compatible gasket materials before placing into chemical service.
