If you are a part of any plumbing industry or linked to it by any means, you should know the basic types of connections that ensure the system is leak-free and reliable.
These connections provide the longevity and working of the valves to their fullest, sealing them 100 percent to ensure maximum functionality. This blog will discuss the basic types of connections used in plumbing systems. They are:
- c x c or copper x copper
- sweat x sweat
- solder x solder
Their names may confuse you initially, but by the end of the article, you will know how these connections and their uses are different.
C X C or Copper X Copper Connections:
Copper x copper is the connection involving copper pipes on both sides of the valves. This connection is primarily used in plumbing systems. Their demand is due to the durable and anti-corrosive nature of copper.
Uses and Applications of C X C Connections:
- c x c connections are widely used for water supply lines in residential plumbing.
- They are used in commercial water supply and heating applications.
- They are installed in different heating and cooling systems due to their thermal conductivity.
- These valves are also used to transfer chemicals and fluids due to their effortless handling of extreme temperatures and pressures.
- These connections are used to replace worn-out and old copper pipes.

Limitations or Disadvantages of C x C Connections:
Although the c x c connections are widely used in various plumbing and HVAC systems as they are reliable, but also have some limitations with their use, which are:
- These valves are only compatible with copper, which limits their use with other materials like PEX or PVC.
- Their proper installation requires soldering skills, which is a time-consuming process and requires experience to carry out.
- Being an expensive metal, the cost of the projects is higher when compared to other alternative materials like PEX.
- Although copper is anti-corrosive, it can be affected by highly acidic or alkaline water, leading to long-term damage.
Sweat x Sweat Connections:
Sweat x sweat is those connections that have soldering on both ends. Sweating is a special term for soldering that is used explicitly in plumbing.
What Is Sweating?
Sweating is a particular term used in plumbing for the process of soldering. During this process, copper pipes are heated with a propane torch to allow the metal mixture (having a low melting point) to melt, thus flowing into the joint. The resulting fluid creates a strong leak-proof seal in the connection.
Common Applications and Benefits of Sweat X Sweat Joints:
- They are used to manage the flow of water in plumbing systems.
- Sweat-soldered connections are used due to their durability and long-lasting nature without crashing.
- They work in hot and cold supply and gas lines in residential, commercial, and industrial settings.
- Sweat-soldered copper valves and fittings are anti-corrosive and used in water conditions.
- They are cost-effective compared to connections made from other means, as all the required materials are easily available.
Solder x Solder Connections:
Solder x solder connections are valves joined to copper pipes with the solder’s help during soldering.
These connections are the same as the sweat x sweat valves. The sweat and soldered connections refer to the same type of valve connections. The terms soldering and sweating are used interchangeably, but sweating is a more accepted term in the plumbing industry.
What is a solder?
A solder is a metal alloy or mixture having low melting points, like tin and lead. It attaches different metal work pieces to seal between the surfaces as a filler.
What is the Difference between Soldering and Sweat Soldering?
The solder (acts as a filler material) is melted with the help of a propane torch to fill gaps in between connections, which is called soldering. It is a broad term used for different types of soldering in various fields like electronics and metalwork, whereas sweating is used in the plumbing industry. Sweating usually involves the same steps as soldering.
Comparison between C X C, Sweat X Sweat, And Solder X Solder Connections
| c x c connections | sweat x sweat | solder x solder |
| They can be installed easily as they do not require heating for soldering | Installation of sweat connections is a long process due to heating and soldering. | Installation is usually similar to sweat x sweat but might require some additional techniques |
| Are used in places that have non-permanent connections | Are useful in places requiring permanent connections, for example, water supply connections | Are robust and leak-proof joints widely used in extreme temperatures and pressures |
| Are reusable and reversible
| They are irreversible, and their removal requires cutting the pipe | Are non-reversible, similar to sweat x sweat |
| Are less durable when compared to soldered joints
| Show reliability and durability for long-term use | Are durable and show high potential strength in joints |
How to Do Specific Soldering (Sweating) In a Step-By-Step Way:
You can do sweating by following these basic and easily doable steps.
- Gather your supplies, including a pipe cutter, wire brush, sandpaper, fire-resistant cloth, propane torch, adjustable wrench, safety gloves, soldering flux, and pipes and fittings.
- Prepare and clean the pipes from any dirt, grease, or grime, especially those surfaces to be joined.
- Cover the prepared surfaces with flux (a chemical cleaning agent that removes oxidation) to help the solder flow quickly into the surfaces.
- Assemble and fit the joints together.
- Expose the joint to heating using a propane torch to the point where it can melt the solder.
- Introduce the solder wire to the heated joint. This will allow it to melt, flowing into the connections and creating a seal.
- Allow it to cool, then observe it closely to ensure an even spread around the connection.

Final Remarks
After learning the different types of valves and fittings like c x c (copper x copper), sweat x sweat, and solder x solder, we can easily identify their needs, uses, and applications in different places. This will allow us to make more informed choices when selecting the specific valve or fitting. Furthermore, proper installation and maintenance can enhance the performance and life span of these connections.

FAQ’s:
What is a Sweat Fitting?
Sweat fittings are the same as soldered fittings and are valve connections used to join copper pipes in a process called sweating to regulate the water flow.
How long is the Life of a Soldered Joint?
A soldered joint can last from a few years to several decades. Their resilience depends upon the solder’s quality, environmental conditions, and joint mechanical stress.
How Do You Ensure A Leak-Proof Solder Joint?
To create a leak-proof solder joint, deeply clean the joint surfaces, apply a generous amount of flux and solder, and provide even heating.
What Types Of Pipes Should I Use With Sweat Fittings?
Sweat fittings are commonly used with copper pipes, but other compatible metals, such as brass, can also be used.
Can I Use Lead-Free Solder For Sweat Fitting?
Due to the raised awareness regarding health and environmental regulations, lead-free solders are a great option available in the market, thus providing a safe and lead-free connection.
