Solder Ring Copper Fitting

Solder Ring Copper Fitting

A solder ring fitting is a pre-soldered capillary connector for joining copper pipes used in plumbing. During the manufacture of these precision-made fittings, a ring of high quality lead-free solder is positioned in each capillary socket. When heat is applied, the solder is released into the gap between the tube and the fitting, resulting in a totally sound joint without the need to end feed additional solder. We provide the size of 8mm-54mm of the full range of products, which are made from copper. The impermeable nature of the solder ring fittings gives excellent protection against contaminants that can threaten the domestic water supply.

Solder Ring Fittings On Gas PipePerformance Advantages


Copper solder fittings are highly reliable and offer a leak-proof joint. The pre-soldered fitting forms a tight seal around the pipe, preventing any gas or liquid from escaping.

Safe, strong and reliable

Solder ring fittings are highly durable and long-lasting. They are made from high-quality materials, such as copper and brass, which are resistant to corrosion and rust.

Quick installation

End feed soldering fittings are easy and quick to install. The pre-soldered joint eliminates the need for any additional soldering, which reduces the installation time and labor cost.


Copper fittings with solder are compatible with a wide range of pipes, including copper, brass, and steel. This makes them a versatile solution for many gas and plumbing installations.

No fire hazard

Solder ring fittings do not require any open flames, which eliminates the risk of fire hazards during installation. This makes them a safer option for gas pipe installations.

How strong are soldered copper joints

Soldered copper joints can be quite strong if done properly. The strength of a soldered joint depends on several factors, including the quality of the solder, the cleanliness of the surfaces being joined, the fit between the pieces being joined, and the temperature and duration of the soldering process.

When copper pipes or other copper parts are joined by soldering, a filler metal (solder) is melted and allowed to flow into the joint between the parts. The solder cools and solidifies, creating a bond between the parts that is typically stronger than the copper itself.

A properly solder ring jointscan be as strong as the copper pipe or part itself, meaning that it should be able to withstand the stresses and pressures that the pipe or part will encounter in normal use. However, if the joint is not done properly, it may be weaker than the copper and may fail under stress.

It's important to note that while solder ring joints can be strong, they are not suitable for all applications. For example, in high-pressure or high-temperature environments, other types of joining methods may be necessary to ensure the strength and integrity of the joint.
