Nibco B213800 Hy-set Hanger Coupling 3/4 in Cast Copper

Product Description

The NIBCO B213800 is a cast copper Hy-Set hanger coupling designed for 3/4-inch copper pipe systems using sweat (C) end connections. This pressure fitting combines a pipe coupling with an integrated hanger function, allowing installers to join and support a copper run in a single fitting. It meets ASME B16.18 and ASTM B584 standards, making it suitable for potable water, hydronic heating, and general plumbing pressure applications. Licensed plumbers and pipefitters install this fitting as part of rough-in and overhead piping work where support and continuity are needed at the same point in the line.

The B213800 is used in residential and light commercial plumbing and hydronic systems where 3/4-inch copper tubing is run horizontally or along structural members. The hanger-style body lets the installer fasten the fitting directly to framing or structural supports, eliminating a separate pipe clamp or hanger at that location. It is well suited for supply lines, recirculation loops, and hot and cold distribution piping where neat, code-compliant support intervals are required.

Key Features

• Integrated hanger and coupling in one cast copper body — eliminates a separate pipe support at the joint
• 3/4-inch sweat (C) end connections for standard copper tubing
• Cast copper construction per ASTM B584 for durability in wet and high-temperature service
• Pressure fitting rated per ASME B16.18 for use in pressurized plumbing and hydronic systems
• Compact, low-profile design allows mounting close to framing or structural members

Compatibility

Designed as an OEM-style pressure fitting replacement for 3/4-inch copper tube systems using sweat end connections in residential and light commercial plumbing and hydronic applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and drain the water supply and relieve system pressure before cutting into an existing line. Clean and flux all mating surfaces before soldering; use lead-free solder for potable water systems as required by code. Secure the hanger body to the structural support before completing the solder joints to avoid stressing the fitting during fastening.
