Matco-norca zmbff05 Black Malleable Floor Flange 1 Inch

Product Description

The MATCO-NORCA zmbff05 is a 1-inch black malleable iron floor flange used to anchor pipe runs to floor surfaces in plumbing and gas distribution systems. Malleable iron construction provides the ductility and thread-holding strength required for secure, long-lasting connections in both residential and light commercial applications. This fitting accepts a 1-inch pipe thread and mounts flat to a floor surface, providing a stable base where vertical pipe transitions from below or terminates at floor level. Licensed plumbers and pipefitters install this type of flange in water supply, gas, and steam piping systems where a solid, low-profile floor connection is required.

The zmbff05 floor flange is suited for residential and commercial plumbing and piping installations where a 1-inch pipe must be secured to a concrete, wood, or structural floor. Typical applications include gas riser connections, water supply stub-outs, and decorative or structural pipe work where the fitting will be visible and must present a clean, finished appearance. The black finish is standard for gas distribution piping and blends with black iron pipe systems commonly used in commercial kitchen, fire suppression, and industrial plumbing layouts.

Key Features

• 1-inch nominal pipe size for direct connection to standard 1-inch black iron pipe
• Malleable iron construction offers superior impact resistance and thread integrity compared to cast iron
• Black finish suits gas distribution and exposed decorative pipe installations
• Flat floor-mount base allows secure fastening to wood, concrete, or structural substrates
• Compatible with standard NPT pipe thread systems

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1-inch black iron pipe systems, including plumbing, gas distribution, and steam piping applications using NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and gas codes, including IPC and IFGC requirements. Shut off all gas or water supply and depressurize the line before removing or installing any threaded fittings. Use appropriate pipe thread sealant rated for the service medium — do not use standard Teflon tape on gas service fittings unless the tape is rated for gas. Secure the flange base to the substrate with fasteners appropriate for the floor material before making the pipe thread connection.
