Southwire 551 Malleable Floor Flange 0.75 in Pipe Fitting

Product Description

The SOUTHWIRE 551 is a malleable floor flange designed for securing pipe runs at floor level in residential and commercial plumbing and mechanical installations. Floor flanges are threaded fittings that anchor vertical or angled pipe to a floor surface, providing a stable base and a finished appearance at the pipe termination point. This fitting is sized for 0.75-inch pipe and is constructed from malleable material, offering durability under the mechanical stress typical of floor-mounted pipe assemblies. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

The 551 floor flange is suited for use in residential plumbing systems, light commercial mechanical rooms, and industrial pipe support applications where a 0.75-inch pipe must be anchored securely to a concrete, wood, or structural floor surface. It is appropriate for use in both new construction and retrofit installations where existing pipe runs require floor-level anchoring or replacement of a worn or damaged flange fitting.

Key Features

• Malleable construction for resistance to mechanical stress and impact
• Sized for 0.75-inch pipe connections
• Floor-mount design provides stable anchoring of vertical pipe runs
• Suitable for residential and light commercial plumbing and mechanical applications
• One-year limited warranty

Compatibility

Designed as an OEM-style replacement or new-installation floor flange for 0.75-inch pipe in standard residential and commercial plumbing and mechanical piping systems.

Installation Notes

Installation of floor flanges should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the pipe system before removing or installing any threaded fitting. Ensure the floor surface is level and structurally sound before fastening the flange. Do not overtighten threaded connections, as malleable fittings can crack under excessive torque.
