Choosing Right En13348 Copper Fittings for Your Next Project

Choosing Right En13348 Copper Fittings for Your Next Project

Copper fittings are often the go-to choice for plumbing and heating installations. This is because copper has excellent thermal and physical properties. However, choosing the right copper fittings for your project is crucial, as the wrong parts can cost you more in the long run. To ensure you make the best decision, we will discuss the different types of EN13348 copper fittings in this blog post.

What is En13348 Copper Fittings?

LEn13348 Copper Fittings are industrial-grade copper fittings used in plumbing systems. They meet the highest grade quality assurance standards set by EN 13348, which is part of the European Standards Association for Fittings and water pipe systems. These copper fittings provide excellent corrosion resistance and a long life span, making them an ideal choice for any piping system. They can be used in hot and cold water and gas lines. Additionally, they have very good impact strength and are known for their durability even when exposed to high temperatures or pressures.

Selecting the Ideal EN13348 Copper Fittings for Your Next Project

EN13348 Copper Fittings

The EN13348 standard specifies the requirements for compression fittings made of copper alloys with or without plating for applications in drinking water installations. EN13348 Copper fittings are widely used in residential, commercial, and industrial buildings, heating, ventilation and air conditioning (HVAC) systems, and fluids transport. There are two primary groups of EN13348 Copper fittings: Compression Copper Fittings and Solder Ring Copper Fittings.

Compression Copper Fittings

These fittings are popular because they are easy to install without soldering, making them a preferred choice for DIYers. Compression fittings use a brass nut and an olive to compress the copper pipe and make a sealed joint. However, these fittings are only suitable for low-pressure applications and temperatures up to 70°C. They are also prone to leaks if not installed correctly.

Solder Ring Copper Fittings

Solder ring fittings are better suited to higher pressure and temperature applications. These fittings have a pre-installed ring of lead-free solder, which melts when you heat the fitting’s end with a suitable gas torch. This fitting method does not require a flux, making installation quicker than traditional soldering. However, incompatible metals, incorrect cleaning, or overheating can cause the pre-installed ring to fail, leading to leaks, so it’s important to ensure a professional does the installation.

Choosing the Right EN13348 Copper Fittings

When choosing the right EN13348 copper fitting for your project, consider the working pressure, temperature range, environment, and application type. For example, you may choose compression fittings for domestic hot and cold-water applications as they are affordable, easy to install, and pressure and temperature-rated for up to 16 bar and 70°C, respectively. However, for higher-pressure applications, such as heating systems, you may choose solder ring fittings that offer higher strength and durability.


Choosing the right EN13348 copper fittings for your next project can save you time and money and guarantee your system performs as it should. Compression fittings are best for low-pressure, low-temperature applications such as hot and cold water, and solder ring fittings are best for high-pressure applications such as heating systems. For larger projects, consider hiring a professional installer to ensure your fittings are appropriately installed, and choose a reliable supplier that offers quality fittings from reputable sources.
