Nibco B056000 Cast Copper 90 Close Rough Elbow 1-1/4x1

Product Description

The NIBCO B056000 is a cast copper 90-degree close rough elbow designed for sweat-connect pressure piping systems. It features a 1-1/4 inch by 1 inch reducing configuration with copper-to-copper (C x C) end connections, making it a direct solder-joint fitting. The close rough pattern provides a tight turn radius suited for installations where space is limited. This fitting is built for pressure service in water supply and hydronic applications and is installed by licensed plumbers working on residential and light commercial systems.

This elbow is used in copper pressure piping systems where a 90-degree directional change is needed with a simultaneous reduction from 1-1/4 inch to 1 inch. Typical applications include domestic water supply lines, hydronic heating branch connections, and in-wall or in-slab rough-in work. The close rough design is particularly useful in tight mechanical spaces where standard-radius fittings cannot be accommodated.

Key Features

• Cast copper construction for consistent wall thickness and reliable solder joints
• 90-degree close rough pattern for tight-radius turns in confined spaces
• Reducing 1-1/4 inch x 1 inch sizing eliminates the need for a separate reducer
• C x C end connections accept standard sweat-solder assembly
• Rated for pressure service in water supply and hydronic piping systems

Compatibility

Designed as an OEM-style pressure fitting for copper sweat-joint piping systems following ASTM and applicable plumbing code standards for water supply and hydronic service.

Installation Notes

Installation is performed by a licensed plumber using standard copper soldering tools including a torch, flux, and lead-free solder per applicable plumbing codes such as the IPC or UPC. Shut off and drain the water supply before cutting into any existing line. Clean and flux all mating surfaces thoroughly before applying heat. Allow the joint to cool fully before restoring system pressure.
