Sigma 811105618 Fig 3190 Floor Flange 1-1/4 in Malleable Iron

Product Description

The SIGMA 811105618 is a FIG 3190 floor flange designed for securing pipe to floor or wall surfaces in piping assemblies. Rated at 150 lb, this flange is manufactured from malleable iron and features a threaded connection for straightforward field installation. The galvanized finish provides corrosion resistance in exposed or mildly corrosive environments. Sized at 1-1/4 inch nominal pipe size, it is a standard fitting used by licensed plumbers and pipefitters on commercial and residential piping projects where a secure, code-compliant pipe anchor is required.

This floor flange is suited for use in drain, waste, and general plumbing piping systems where a 1-1/4 inch nominal threaded pipe needs to be anchored at a floor or wall termination point. Typical applications include support of exposed pipe runs, base connections in wet environments, and mechanical room piping installations. The 150 lb pressure class makes it appropriate for standard service conditions in both residential and light commercial settings.

Key Features

• FIG 3190 pattern — standard floor flange configuration for anchoring threaded pipe
• Malleable iron construction for strength and resistance to impact and vibration
• Galvanized finish for corrosion protection in exposed installations
• Threaded connection for tool-standard field make-up without welding
• 150 lb pressure rating for standard service piping applications
• 1-1/4 inch nominal pipe size for compatibility with standard pipe and fittings

Compatibility

Designed as an OEM-style replacement or new-installation floor flange for 1-1/4 inch nominal threaded pipe systems in standard 150 lb service class piping assemblies.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the piping system before making up or breaking threaded connections. Use appropriate pipe thread sealant or PTFE tape on all threaded joints per local plumbing code requirements. Secure the flange to the mounting surface using fasteners appropriate for the substrate material and load conditions.
