Threaded Copper Tube for HVAC, Plumbing and Industrial Applications
Threaded copper tube is a specialized form of copper tubing where threads are machined at the ends to enable mechanical connections. It is used in systems where easy assembly, disassembly and maintenance are required without the need for soldering or brazing.
Although copper tubes are typically joined using soldering or brazing, threaded connections are essential in specific applications such as gas systems, industrial equipment and modular piping networks.
What is Threaded Copper Tube?
Threaded copper tube refers to copper tubing that has internal or external threads cut into its ends. These threads allow the tube to connect with threaded fittings such as couplings, unions and adapters.
Threading is usually applied to thicker-walled copper tubes or through adapters to maintain structural integrity.
Types of Threaded Copper Tube Connections
Male Threaded Copper Tube
External threads are machined on the tube ends, allowing connection to female threaded fittings.
Female Threaded Copper Tube
Internal threads are present to receive male threaded components.
Threaded Copper Adapters
Used to connect copper tubes with threaded steel, brass or plastic systems.
Hybrid Threaded Fittings
Combination fittings that include threaded-to-solder or threaded-to-compression connections.
