Nibco b49560l 3 in Cast Copper Sweat 150 Companion Flange

Product Description

The NIBCO b49560l is a 3-inch cast copper sweat companion flange rated for 150 PSI service. This fitting is part of the NIBCO 771-LF product line and is designed to connect copper piping systems to flanged equipment, valves, or other flanged components. The sweat-end connection is soldered directly onto copper tube, creating a secure, leak-resistant joint. Licensed plumbers and pipefitters install this flange type in commercial and residential hydronic, potable water, and mechanical piping systems where a bolted flange connection is required.

This companion flange is suited for use in wet piping systems where a removable, bolted joint is needed at equipment connections such as pumps, valves, strainers, and similar flanged components. The 3-inch fitting size accommodates standard 3-inch copper tube and pairs with a matching companion flange or flanged equipment face bolted together with a gasket. Typical applications include commercial plumbing, hydronic heating and cooling distribution piping, and mechanical room equipment connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with local plumbing codes and applicable IPC requirements. Shut off and depressurize the system and drain the line before soldering the sweat connection. Use appropriate flux and lead-free solder compliant with local potable water regulations. Bolt the companion flange to its mating flange with a proper gasket and torque fasteners evenly in a cross pattern per the gasket and flange manufacturer guidelines.
