Equal copper coupling
First of all, an equal coupling joins compatible copper tubes of the same confirmed outside diameter.
Review specification details →Product overview
Copper Socket & Coupling fittings for straight connections
In addition, S K Metal supplies copper sockets and couplings for joining compatible copper tubes in aligned piping runs.
Moreover, each fitting must match the tube OD, wall thickness, socket bore, insertion depth, internal-stop arrangement and joining method. However, the words “socket” and “coupling” may describe different patterns across projects. Therefore, buyers should provide the applicable dimensional and system specification before ordering.

Types and configurations
Choose the correct Copper Socket & Coupling
First of all, confirm whether the fitting joins equal or different tube sizes. Then verify bore, depth, stop arrangement and joining method.
Reducing copper coupling
In addition, a reducing pattern joins two confirmed tube sizes through different socket dimensions.
Provide both tube sizes →Stop coupling
However, an internal stop controls tube insertion and should match the specified assembly method.
Define the stop requirement →Slip or repair coupling
Moreover, a stop-free pattern allows positioning along compatible tubing for an approved repair procedure.
Discuss installation details →Expanded copper socket
Furthermore, an expanded socket must be defined by mating OD, insertion depth, clearance and joining method.
Request dimensional review →Custom Copper Socket & Coupling
Finally, drawing-based bore, length, wall, stop and end details can be reviewed for project requirements.

How to specify a Copper Socket & Coupling
Therefore, a complete specification helps prevent errors in tube fit, socket bore, insertion depth, stop arrangement and joining requirements.
- Tube dimensions
- First of all, provide the outside diameter and wall thickness for each adjoining copper tube.
- Socket dimensions
- Next, state the bore, insertion depth, overall length, fitting wall and dimensional tolerances.
- Coupling pattern
- Also confirm equal or reducing size, internal stop or slip pattern and any end-orientation requirement.
- Material & temper
- Moreover, identify copper grade, temper 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 purpose and equipment reference.
- Quantity & delivery
- Therefore, include piece quantity, packaging, inspection, delivery city and required date.
Important: Do not select a coupling from OD alone. Therefore, the system designer should approve both connections, bore, depth, stop type, material, ratings and joining procedure.
Applications
Applications of Copper Socket & Coupling fittings
Because systems differ, the correct coupling depends on tube dimensions, connection purpose, joining method and operating conditions.
HVAC and refrigeration
For example, compatible couplings join aligned refrigerant tubes within an approved system layout.
VRV and VRF systems
Moreover, specified sockets can connect compatible tube runs in multi-split refrigerant networks.
Plumbing systems
In addition, suitable couplings provide straight connections in compatible hot and cold water pipework.
Repair connections
Furthermore, slip couplings may support approved repair work where tube access and alignment permit.
Heat-transfer equipment
However, coil and equipment connections may need drawing-controlled socket and insertion dimensions.
OEM assemblies
Therefore, repeat components should be approved by drawing, sample, tolerance and inspection criteria.
Quality and documentation
Verify socket dimensions and inspection requirements
Before ordering, define the OD, bore, depth, stop, wall and length checks required for the exact Copper Socket & Coupling. In addition, designers can review the Copper Tube Handbook for general information about copper tube and joining practices.
Discuss your material requirement →- Tube OD, wall and socket-fit verification
- Bore, insertion depth and stop checks
- Roundness, surface and workmanship review
- Material and inspection documents when quoted
- Orientation, packaging and component identification
Ordering checklist
How to order a Copper Socket & Coupling
For an accurate quotation, send the fitting schedule or drawing together with the complete tube and service specification.
Name the coupling
First of all, state equal, reducing, stop, slip, repair or drawing-based configuration.
State tube and socket dimensions
Next, provide both tube ODs, walls, socket bores, insertion depths, overall length and tolerances.
Define the stop and ends
Then list internal-stop details, plain or expanded ends and required joining clearances.
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 Socket & Coupling FAQs
What is a Copper Socket & Coupling used for?
In general, it joins two compatible copper tubes in a straight line. The bore, depth, stop arrangement and ends must match the system specification.
Which dimensions are required for a quotation?
In addition, provide both tube ODs and walls, socket bores, insertion depths, overall length, fitting wall and tolerances.
What is the difference between stop and slip couplings?
A stop coupling limits insertion at its centre. However, a slip coupling omits that stop so it can move along compatible tubing during an approved installation.
Are reducing copper couplings available?
However, availability depends on both connection sizes, socket geometry and quantity. Therefore, submit the complete size schedule for review.
How are copper sockets joined?
In general, the approved method depends on socket 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.
