Elkhart Products NL41-150-24 Cast Copper Flange 1-1/2 in

Product Description

The ELKHART PRODUCTS NL41-150-24 is a Class 150 cast copper companion flange designed for copper solder-cup installations in plumbing and mechanical piping systems. The fitting incorporates a solder cup end and a flat flange face, allowing a technician to transition from a standard solder-joint copper line to a bolted flange connection. At 1-1/2 inches nominal pipe size, this flange is suited for commercial and residential hydronic, water service, and process piping applications where a removable, bolted joint is required. Licensed plumbers and pipefitters install this type of fitting wherever future serviceability or equipment isolation is a design requirement.

This companion flange is used in copper piping systems where a solder-to-flange adapter is needed, such as connections to pumps, valves, heat exchangers, and mechanical equipment flanges rated at Class 150. The fitting is cast copper, making it compatible with standard copper tube and fittings used in potable water, HVAC hydronic loops, and light commercial mechanical systems. Sustainable building projects benefit from the reusability and recyclability of copper as a base material.

Key Features

• Solder cup inlet allows direct connection to standard copper tube using conventional soldering techniques
• Flat flange face mates with Class 150 companion flanges and equipment ports
• Cast copper construction provides durability and corrosion resistance in water and hydronic service
• 1-1/2 inch nominal size fits standard copper pipe dimensions
• Copper material supports use in sustainable and green building projects due to reusability

Compatibility

Designed as an OEM-style solder-cup companion flange for Class 150 copper flange applications in residential and commercial plumbing and hydronic piping systems at 1-1/2 inches nominal pipe size.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable plumbing codes such as the IPC. Shut off and depressurize the system and allow all piping to cool completely before soldering or unbolting any flange connection. Use appropriate flux and solder rated for the intended service when making the solder-cup joint, and allow the joint to cool fully before applying pressure. Flange bolting should follow standard Class 150 gasketed joint practices using a suitable flange gasket between mating faces.
