Nibco NL41-150-32 2 Inch Class 150 Copper Flange

Product Description

The NIBCO NL41-150-32 is a one-piece, Class 150 copper flange fitting designed to transition a solder (sweat) connection to a flanged pipe connection. The fitting incorporates a solder cup end and a flat flange face, allowing a copper tubing run to terminate at a bolted flange joint. At 2 inches nominal size and rated Class 150, it is suited for low-to-moderate pressure water and fluid systems in commercial and residential plumbing applications. Licensed plumbers and pipefitters install this type of fitting where a copper distribution line must connect to flanged valves, pumps, or equipment. The copper construction delivers inherent corrosion resistance, long service life, and minimal maintenance over the system lifespan.

This flange fitting is used in plumbing systems where a 2-inch copper sweat line meets flanged equipment or valves rated for Class 150 service. Typical applications include mechanical rooms, boiler rooms, pump stations, and commercial water distribution systems. The one-piece construction eliminates the need for a separate flange adapter and stub end, simplifying assembly at the flange joint. Its copper material makes it appropriate for projects requiring recyclable or sustainable materials, as copper is fully reusable at end of service life.

Key Features

• One-piece construction integrates solder cup and flange face in a single fitting
• Class 150 pressure rating suitable for standard low-to-moderate pressure plumbing service
• 2-inch nominal size with solder cup end for sweat connection to copper tubing
• Copper material provides corrosion resistance and long-term durability with low maintenance
• Manufactured in an ISO 9001 certified facility for consistent dimensional quality
• Backed by a 50-year limited warranty from NIBCO

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 2-inch copper tubing systems requiring a Class 150 flanged termination point.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off and drain the system completely before soldering or disassembling any flange connections. The solder cup end requires standard sweat-soldering practice with appropriate flux and lead-free solder per code. Flange bolting should follow Class 150 flange bolt patterns and gasket requirements; consult NIBCO technical data sheets for engineering and torque guidance specific to this fitting.
