Nibco B345850 Cast Copper 45 Wye 2 Inches Cxcxc

Product Description

The NIBCO B345850 is a cast copper 45-degree wye fitting designed for pressure piping systems. It connects three pipe runs at a 45-degree angle using a solder-cup end connection on all three ports (C x C x C), making it suitable for branch takeoffs in copper water distribution and plumbing systems. The fitting is manufactured from cast copper to ASTM B584 and ISO standards, delivering the wall thickness and structural integrity required for pressure-rated applications. At 2.17 pounds, it is a full-size 2-inch fitting intended for professional installation by licensed plumbers and pipefitters.

This fitting is used in residential and commercial copper pressure piping systems where a 45-degree branch connection is needed. Typical applications include domestic hot and cold water supply, hydronic heating distribution, and general pressure piping where a wye configuration is preferred over a tee for smoother flow transition. The solder-cup ends accommodate standard 2-inch copper tube soldered in place with lead-free solder per applicable plumbing codes.

Key Features

• 45-degree wye geometry allows angled branch connections for smoother flow compared to a standard tee
• C x C x C end connections accept standard 2-inch copper tube on all three ports
• Cast copper construction meets ASTM B584 and ISO standards for pressure fittings
• Pressure-rated fitting suitable for potable water and hydronic systems
• Full 2-inch fitting size for main-line branch applications

Compatibility

Designed as an OEM-style pressure fitting compatible with standard 2-inch copper tube soldered connections in residential and commercial plumbing pressure piping systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local equivalent. Shut off and drain the water supply before cutting into any existing piping. Clean all mating surfaces with emery cloth and apply flux before soldering; use lead-free solder for potable water applications as required by code. Allow the joint to cool fully before restoring system pressure.
