1. What Are Solder Joint Fittings?

Solder joint fittings, also known as Yorkshire fittings, are a type of plumbing fitting used to connect pipes together. They are made of copper and feature a pre-installed ring of solder inside the fitting. The solder is exposed when heat is applied during the installation process, creating a strong and reliable joint between the fitting and the pipe.

2. How Do Solder Joint Fittings Work?

Solder joint fittings utilize a simple yet effective mechanism to create a leak-free connection. When heat is applied to the fitting, the solder inside melts and forms a bond with the copper pipe. As the solder cools and solidifies, it creates a strong joint that is both watertight and resistant to corrosion. This seamless connection ensures the longevity and durability of the plumbing system.

3. The Advantages of Copper Fittings with Solder Ring

Copper fittings with solder ring offer several benefits that make them a preferred choice for plumbing installations. Here are some key advantages:

Quick and Easy Installation

One of the main advantages of solder joint fittings is their ease of installation. With the pre-installed solder ring, there is no need for additional flux or soldering paste. This saves both time and effort during the installation process, making it more efficient for plumbers and DIY enthusiasts alike.

Reliability and Longevity

Copper fittings with solder ring provide a reliable and long-lasting connection. The solder joint creates a strong bond between the fitting and the pipe, ensuring that it will withstand the test of time. This reduces the likelihood of leaks or pipe failures, giving you peace of mind and saving you from potential repair costs in the future.


Solder joint fittings are compatible with various types of pipes, including copper and plastic. This versatility makes them suitable for a wide range of plumbing applications, whether in residential, commercial, or industrial settings. With the ability to connect different pipe materials, copper fittings with solder ring offer flexibility and convenience in installations.

Corrosion Resistance

Copper, the primary material used in solder joint fittings, is known for its excellent corrosion resistance. This means that the fittings will not easily degrade or deteriorate over time, even when exposed to moisture and other harsh environmental conditions. The corrosion resistance of copper fittings with solder ring contributes to their longevity and reliability.

4. A Step-by-Step Guide to Installing Soldered Plumbing Fittings

Installing soldered plumbing fittings requires precision and attention to detail. Follow these steps to ensure a successful installation:

Step 1: Prepare the Pipes

Clean and deburr the ends of the pipes that will be joined. This involves removing any burrs or imperfections that may affect the quality of the joint. Ensure the pipe ends are clean and smooth before proceeding to the next step.

Step 2: Apply Flux

Apply a thin layer of flux to the outside of the pipe and the inside of the copper fitting with solder ring. Flux helps facilitate the soldering process by preventing oxidation and ensuring a clean surface for the solder to adhere to.

Step 3: Insert the Pipe

Insert the pipe into the copper fitting with solder ring, ensuring a snug fit. Make sure the pipe is fully inserted up to the stop inside the fitting. This ensures proper alignment and maximizes the strength of the joint.

Step 4: Apply Heat

Using a blowtorch or a soldering iron, apply heat evenly to the fitting. Move the heat source around the fitting to distribute the heat uniformly. The heat will cause the solder inside the fitting to melt and create a strong bond with the pipe.

Step 5: Allow the Joint to Cool

Once the solder has melted and formed a secure joint, remove the heat source and allow the joint to cool naturally. Avoid disturbing the joint during the cooling process to ensure a solid and leak-free connection.

Step 6: Inspect and Test

After the joint has cooled, inspect it for any signs of defects or leaks. Perform a pressure test to ensure the integrity of the connection. If the joint passes the inspection, it is ready for use.

5. Other Joining Methods

When it comes to joining pipes, there are several methods available, each with its advantages and limitations. Here is a comparison of other common joining methods to copper fittings with solder ring:

Joining MethodAdvantagesLimitations
Copper Fittings with Solder RingQuick and easy installationRequires heat for installation
Compression FittingsNo heat required, reusableRequires additional fittings, bulkier
Push-Fit FittingsQuick and easy installationLimited to specific pipe materials, higher cost
WeldingExtremely strong joints, permanentRequires specialized equipment and expertise

6. Common Applications of Soldered Pipe Connectors

Copper fittings with solder ring find applications in various plumbing systems. Some common uses include:

  • Domestic water supply systems
  • Heating and cooling systems
  • Gas distribution systems
  • Plumbing for residential, commercial, and industrial buildings
  • HVAC (Heating, Ventilation, and Air Conditioning) installations

The versatility of copper fittings with solder ring makes them suitable for a wide range of plumbing projects, whether large or small. These fittings are available in a range of sizes to accommodate different plumbing sizes including 8mm,10mm,12mm,15mm,22mm,28mm,35mm,42mm and 54mm.

7. Troubleshooting: Common Issues and Solutions

While copper fittings with solder ring are generally reliable, there can be instances where issues may arise. Here are some common problems and their solutions:


If you notice a leak at the solder joint, it may indicate an insufficient solder connection. In such cases, the joint needs to be re-soldered. Ensure proper cleaning and flux application before re-installing.

Uneven Heating

Uneven heating can lead to weak or incomplete solder joints. Make sure to evenly distribute the heat around the fitting to achieve a consistent and secure bond.


Overheating can cause the solder to melt excessively, leading to leaks or weakened joints. Follow the recommended heating guidelines and avoid applying excessive heat to prevent such issues.

8. Solder Joint Fittings vs. Yorkshire Fittings

It’s worth noting that solder joint fittings and Yorkshire fittings are essentially the same. Yorkshire is a well-known brand that specializes in manufacturing high-quality solder joint fittings. The terms “solder joint fittings” and “Yorkshire fittings” are often used interchangeably in the industry.

9. Different Types of Copper Fittings with Solder Ring

Copper fittings with solder ring come in various types to suit different plumbing needs. Some common types include:

  • Couplings: Used to join two pipes of the same diameter.
  • Elbows: Used to change the direction of the pipe.
  • Tees: Used to create a T-shaped junction in the pipe.
  • Reducers: Used to connect pipes of different diameters.

These are just a few examples of the many types of copper fittings with solder ring available. The specific type needed for a particular installation depends on the plumbing layout and requirements.

10. Conclusion

Solder joint fittings, or Yorkshire fittings, provide a reliable and efficient solution for plumbing connections. Their ease of installation, reliability, versatility, and corrosion resistance make them a preferred choice for professionals and DIY enthusiasts alike.
