Legend Valve 310-259nl Bronze Sweat Companion Flange 2 in

Product Description

The LEGEND VALVE 310-259nl is a 2-inch no-lead cast bronze sweat companion flange designed for connecting copper pipe to flanged fittings or equipment in plumbing and mechanical systems. Cast from no-lead bronze to meet current potable water requirements, this fitting transitions a sweat (solder cup) end to a flat-face or raised-face flange connection. Rated Class 150 and conforming to ASTM B584, it delivers reliable performance in commercial and residential water service, hydronic heating, and mechanical room piping. Weighing 3.65 pounds, the fitting is a solid, heavy-duty component suited for permanent installations. Licensed plumbers and pipefitters are the typical installers for this type of companion flange.

This companion flange is used where a copper sweat connection must terminate at a bolted flange joint — common in pump connections, valve flanges, water heaters, and mechanical equipment hookups in both residential and light commercial settings. The sweat-by-flange configuration allows the installer to solder the fitting directly onto copper tube and then bolt the flange face to a mating flange using a gasket and appropriate hardware. It is well suited for potable water, hydronic, and general plumbing service where a no-lead bronze material is specified or code-required.

Key Features

• No-lead cast bronze construction meets potable water compliance requirements
• Sweat x Flange configuration for direct copper tube solder connection to flanged equipment
• Class 150 pressure rating per standard flanged fitting classifications
• Meets ASTM B584 (bronze alloy), ASTM B16.15 (cast bronze fittings), and ASTM B1.20.1 (pipe thread) standards
• 2-inch size fits standard 2-inch copper pipe
• Solid cast body at 3.65 pounds provides durability in permanent mechanical installations

Compatibility

Designed as an OEM-style companion flange for use with standard 2-inch copper pipe sweat connections terminating at Class 150 flanged equipment or valves in potable water and hydronic plumbing systems.

Installation Notes

Installation of this companion flange is typically performed by a licensed plumber or pipefitter. Shut off and drain the water system completely before soldering the sweat end onto copper pipe, following standard torch-and-flux procedure per applicable plumbing codes. When bolting the flange face to a mating flange, use an appropriate full-face or ring gasket and torque bolts evenly in a cross pattern — consult the mating equipment manufacturer for bolt specifications. Work must comply with applicable local plumbing codes and ASTM standards referenced on the fitting.
