1/2 inch Black Iron Floor Flange

1/2 Inch Black Iron Floor Flange – Threaded Support for Rigid Pipe Installations

The 1/2 inch Black Iron Floor Flange is a threaded pipe fitting designed to anchor pipe to flooring, structural surfaces, or mounting plates in non-pressurized mechanical and plumbing systems. Fabricated from durable black malleable iron, this flange provides a stable base for vertical pipe runs or support brackets where a secure mechanical connection is required.

Advantages of Heavy-Duty Flange Components

Engineered for strength and dimensional consistency, this flange meets typical requirements for industrial-grade plumbing and gas support systems. Key performance characteristics include:

• ✅ CNC-Machined Threads – Delivers accurate pipe engagement and reduced risk of cross-threading during assembly.
• ✅ Cast Iron Body – Provides high compressive strength and long-term resistance to deformation under static loads.
• ✅ Corrosion-Resistant Coating – Black iron finish offers enhanced protection in indoor, dry, and concealed locations.

Installer Considerations

This fitting is designed for use with threaded steel piping. Installation should include application of an approved pipe thread sealant or PTFE tape to ensure leak resistance at the threaded joint. Fasteners should be appropriately sized for the mounting substrate to prevent flange rotation or loosening during service.

Product Specifications

• • Nominal Size: 1/2 inch
• • Material: Black Malleable Iron
• • Connection: FNPT (Female National Pipe Thread)
• • Design: Four-bolt floor mount with threaded center hub
• • Compliance: Lead-free per NSF 372 and ASME B16.3 for non-potable use

Typical Applications

Commonly specified in low-pressure gas, compressed air, or support systems, the 1/2 inch floor flange is often used to secure vertical pipe risers or stabilize structural elements within wall cavities, mechanical rooms, or exposed piping layouts. Not intended for use in pressurized potable water systems.

Code Compliance Note

As required by federal and state regulations, this product is manufactured using lead-free materials suitable for compliance with applicable plumbing and mechanical codes where lead content restrictions are enforced.

This flange is a standard solution for professionals needing consistent thread engagement and reliable surface mounting for pipe configurations requiring fixed-point anchoring. Ideal for utility piping frameworks, mechanical support installations, and retrofit infrastructure upgrades.
