Description
Copper 90 Degree Reducing Elbow - C x C
Charman Inc. Copper 90 Degree Reducing Elbows combine a 90-degree directional change with a transition between two different nominal copper tube sizes. The C x C configuration provides cup-style connections on both ends for soldered copper piping installations.
By incorporating the size transition directly into the elbow, this fitting can simplify piping layouts and eliminate the need to install a separate standard elbow and reducing fitting.
Product Highlights
- Copper 90-degree reducing elbow
- Changes direction and nominal tube size in one fitting
- Copper construction
- C x C cup-style connections
- Solder / sweat installation
- Compact reducing configuration
- Can reduce the number of fittings required for a size transition

What Is a Copper Reducing Elbow?
A copper reducing elbow performs two functions within a single fitting: it changes the direction of the piping run by 90 degrees and transitions between different nominal copper tube sizes.
- Creates a 90-degree change in piping direction
- Transitions between different nominal copper tube sizes
- Accepts compatible copper tube at both cup connections
- Designed for solder / sweat joining
- Can replace a separate elbow-and-reducer combination in suitable layouts
Why Use a Reducing Elbow?
Direction & Reduction
Combines a 90-degree turn and tube-size transition into a single connection point.
Compact Installation
Combining two piping functions into one fitting can help reduce the overall space required for the transition.
Fewer Components
A reducing elbow can eliminate a separate reducer and the additional joints associated with a multi-fitting assembly.
Understanding C x C Connections
Both ends of the elbow use cup-style connections designed to receive compatible copper tube. Each tube end is inserted into the appropriate fitting cup and joined using standard solder / sweat installation procedures.
Because this is a reducing fitting, the two cups accept different nominal tube sizes while maintaining the 90-degree elbow configuration.
Common Applications
Plumbing & Mechanical
- Copper tube installations
- Water distribution piping
- Mechanical piping systems
- Equipment connections
- Branch piping
- Repair and maintenance work
Size Transitions
- Copper tube size changes
- Compact piping layouts
- Piping modifications
- Equipment room piping
- Closely spaced connections
- Fabricated copper assemblies
How to Select the Correct Reducing Elbow
- Identify the nominal copper tube size required at each connection.
- Confirm that the piping run requires a 90-degree directional change.
- Verify that C x C cup-style solder connections are appropriate for the installation.
- Confirm that combining the size transition and directional change in one fitting works with the piping layout.
- Select the variation matching both required connection sizes.
Installation Guidance
- Verify both nominal connection sizes before installation.
- Confirm the elbow orientation and reducing direction before soldering.
- Cut compatible copper tube squarely and remove burrs as appropriate.
- Clean the copper tube and fitting mating surfaces before joining.
- Apply appropriate flux according to the soldering procedure.
- Fully seat the copper tube into each fitting cup.
- Use proper heating and soldering procedures for copper piping.
- Allow completed joints to cool before disturbing the assembly.
- Test the completed piping system for leakage before placing it into service.
Our pipe and fitting specialists can help review your copper tube sizes, reducing configuration, 90-degree piping layout, solder-joint requirements, and application before you order.

What is a reducing elbow?
A reducing elbow changes the direction of a piping run while simultaneously transitioning between two different nominal tube sizes.
Why use a reducing elbow instead of a standard elbow?
A standard elbow changes direction while maintaining the same nominal connection size. A reducing elbow changes both direction and nominal tube size within the same fitting.
Can a reducing elbow eliminate a separate reducer?
Yes. When the piping layout requires both a 90-degree turn and a size transition at the same location, a reducing elbow can eliminate the need for a separate reducing fitting.
What does C x C mean?
C x C indicates that both ends have cup-style connections designed to receive compatible copper tube for solder / sweat joining.
Does the orientation of a reducing elbow matter?
The fitting should be oriented so the larger and smaller connections correspond with the required tube sizes and direction of the piping layout. Verify both connections before soldering.
How are these fittings installed?
They are installed using appropriate copper solder / sweat joining procedures, including tube preparation, cleaning, flux application, proper heating, soldering, and system testing.
Important Ordering Notes
- Verify the nominal copper tube size required at both ends of the fitting.
- Confirm that a 90-degree reducing configuration is appropriate for the piping layout.
- Verify that C x C solder / sweat connections are required.
- Select the variation matching both required connection sizes.
