Concentric reducer
First of all, a concentric pattern keeps the large and small connections on a common centreline.

Copper Reducer fittings for connecting different tube sizes
In addition, S K Metal supplies copper reducing fittings for buyers who need a controlled transition between two compatible copper tube sizes.
Moreover, each fitting must match the large and small tube ODs, wall thicknesses, reducer length, end geometry and joining method. However, nominal size alone does not define the complete component. Therefore, buyers should provide dimensional and operating details for both connections before ordering.

Types and configurations
Choose the correct Copper Reducer configuration
First of all, confirm both connection sizes and the required transition pattern. Then verify wall thickness, length, ends and joining method.
Eccentric reducer
In addition, an eccentric transition offsets the connection centrelines when the approved piping layout requires it.
Discuss orientation requirements →Copper reducing coupling
However, a reducing coupling uses connection geometry designed to join two confirmed copper tube sizes.
Provide both tube sizes →Swaged Copper Reducer
Moreover, swaged transitions should be specified by large end, small end, wall, length and forming details.
Request dimensional review →HVAC reducing fitting
Furthermore, HVAC and refrigeration enquiries should identify tube dimensions, refrigerant service and cleanliness requirements.
Discuss service requirements →Custom reducing fitting
Finally, drawing-based diameters, transition length, wall thickness and end forms can be reviewed for project requirements.

How to specify a Copper Reducer
Therefore, a complete specification helps prevent errors in connection sizes, transition geometry, wall thickness, end preparation and joining requirements.
- Connection sizes
- First of all, provide the outside diameter and wall thickness for both adjoining tubes.
- Reducer dimensions
- Next, state the large-end ID, small-end ID, overall length, insertion depths and tolerances.
- Transition pattern
- Also confirm concentric, eccentric, swaged or drawing-defined geometry and any orientation requirement.
- Material & temper
- Moreover, identify copper grade, temper, fitting wall and applicable tube or project specification.
- Joining requirement
- In addition, specify brazing, soldering, press-fit or another approved installation method.
- Application data
- Finally, provide medium, design pressure, temperature, installation orientation and equipment reference.
- Quantity & delivery
- Therefore, include piece quantity, packaging, inspection, delivery city and required date.
Important: Do not select a reducer from one nominal size alone. Therefore, the system designer should approve both connections, material, wall, transition geometry, ratings and joining procedure.
Applications
Applications of Copper Reducer fittings
Because systems differ, the correct reducer depends on both tube sizes, flow arrangement, joining method and operating conditions.
HVAC and refrigeration
For example, compatible reducers connect different refrigerant tube sizes within an approved system layout.
VRV and VRF systems
Moreover, specified transitions can connect compatible branch or equipment tube sizes in multi-split networks.
Plumbing systems
In addition, suitable reducers provide controlled size changes in compatible hot and cold water pipework.
Heat-transfer equipment
Furthermore, coil and heat-exchanger connections may need drawing-controlled transition dimensions.
Process piping
However, material, pressure, medium and joining requirements must be confirmed for the exact process service.
OEM assemblies
Therefore, repeat components should be approved by drawing, sample, tolerance and inspection criteria.
Quality and documentation
Verify reducer dimensions and inspection requirements
Before ordering, define the connection, length, wall, concentricity or offset checks required for the exact Copper Reducer. In addition, designers can review the Copper Tube Handbook for general information about copper tube and joining practices.
Discuss your material requirement →- Large and small connection verification
- Overall length, wall and transition checks
- Roundness, surface and workmanship review
- Material and inspection documents when quoted
- Orientation, packaging and component identification
Ordering checklist
How to order a Copper Reducer
For an accurate quotation, send the fitting schedule or drawing together with the complete tube and service specification.
Name the reducer
First of all, state concentric, eccentric, reducing-coupling, swaged or drawing-based pattern.
State both tube sizes
Next, provide large and small ODs, wall thicknesses, fitting length, insertion depths and tolerances.
Define the ends
Then list socket, expanded, swaged, plain or other end forms and surface requirements.
Describe the service
In addition, state medium, pressure, temperature, joining method and equipment reference.
Confirm quantity and delivery
Finally, include pieces, sample approval, packaging, destination, schedule and documentation.
Frequently asked questions
Copper Reducer FAQs
What is a Copper Reducer used for?
In general, it connects two compatible copper tubes or components with different connection sizes. Its dimensions and ends must match the system specification.
Which dimensions are required for a quotation?
In addition, provide both tube ODs and walls, large and small fitting IDs, overall length, insertion depths and tolerances.
What is the difference between concentric and eccentric reducers?
A concentric reducer shares one centreline. However, an eccentric reducer offsets the connection centrelines for a specified orientation or layout.
Can custom size combinations be supplied?
However, feasibility depends on both diameters, wall, length, quantity and tooling. Therefore, submit a dimensional drawing for review.
How is a copper reducing fitting joined?
In general, the approved method depends on end geometry and system specification. Consequently, state brazing, soldering, press-fit or another required method.
Can inspection documents be requested?
Yes, but availability varies by order. Therefore, list material, dimensional, inspection and traceability requirements before quotation.
