End Feed vs Solder Ring Fittings
Discover the key differences between End Feed and Solder Ring fittings, their pros, cons, and best uses. Learn which is right for your project here.
Last Updated: Sep 4, 2024
Choosing the right type of fitting is essential for any plumbing or heating system installation, as it directly affects the efficiency, reliability, and longevity of the connections. Two popular options, End Feed and Solder Ring fittings, are widely used for copper pipe installations due to their secure, leak-proof joints. While both fittings are very similar, their installation methods, cost, and ideal applications differ significantly. This guide will provide an in-depth comparison of End Feed and Solder Ring fittings, helping you make an informed decision for your next project.
What Are End feed Fittings?
End feed fittings are a type of soldered fitting used primarily with copper pipes. These fittings consist of a simple fitting body that is soldered to the pipe ends. The joint is made by heating the fitting and pipe with a torch and applying solder, which flows into the joint to create a strong, permanent seal.

Key Components of An End Feed Connection
Fitting Body: Made of copper or brass, designed to fit snugly around copper pipe manufactured to BS EN 1057 standards.
Copper Pipe: Copper tube manufactured to BS EN 1057 standards.
Solder: A metal alloy used to bond the fitting and pipe together when heated.
Flux: A chemical cleaning agent applied to the joint before soldering to prevent oxidation and ensure a strong and clean bond.
How End Feed Fittings Work
End feed fittings rely on capillary action. They are heated to point that allows solder to flow into the small gap between the fitting and the pipe, creating a secure and watertight seal once cooled.
Performance of End Feed Fittings
Soldered Fittings made to BS EN 1254 standards can differ widely in performance depending on the solder type and fitting size. Typically, fittings using lead solder or brazing can withstand pressures up to 16 Bar under normal conditions. With higher-grade solder, such as solder containing Copper or Silver, the pressure rating increases to 25 Bar.

End Feed
Advantages of End Feed Fittings
Strong, Permanent Joints
Soldered joints create a durable, leak-proof seal that can withstand high pressure and temperature changes.Can Support Higher Pressures
Depending on the choice of solder, Capillary Fittings can reach pressure ratings of PN25.Environmentally Friendly Material
Copper is a sustainable and recyclable material, making capillary fittings an environmentally friendly option.Compact Design
Soldered fittings are sleek and low-profile, making them ideal for exposed installations where aesthetics matter or tight spaces where access is limited.Cost-Effective
Generally cheaper than other types of fittings, making them popular for large installations.Highly Reliable
Minimal risk of leaks when installed correctly due to the solid bond between the fitting and the pipe.
Aesthetically Pleasing
End Feed Fittings, especially when made of copper, seamlessly fit in with the pipe they are connecting to.
Disadvantages of End Feed Fittings
Requires Open Flame
The use of a torch introduces safety risks, particularly in areas where flammable materials are present or where heat is restricted.Higher Skill Level Required
Proper soldering technique is crucial; poor preparation or overheating can result in weak joints or leaks.
Time-Consuming Installation
The soldering process for End Feed Fittings requires time and skill, making installation slower compared to other kinds of fittings.
What Are Solder Ring Fittings?
Solder Ring Fittings are a type of soldered fitting used primarily with copper pipes. These fittings consist of a simple fitting body that is pre-soldered by the manufacturer. The joint is made by heating the fitting and pipe with a torch, which releases the solder into the joint to create a strong, permanent seal.
Solder Ring

How Solder Ring Fittings Work
Solder Ring Fittings rely on capillary action. They are heated to point that allows solder inside the fitting to flow into the small gap between the fitting and the pipe, creating a secure and watertight seal, once cooled.

Comparing End Feed and Solder Ring Fittings
End Feed | Solder Ring | |
|---|---|---|
Installation | Requires flux and solder to be applied manually and heated with a torch. | Comes with pre-installed solder, requiring only flux and heating to secure. |
Safety | Uses an open flame, posing fire risks in confined or flammable areas. | Still requires heating, but pre-soldered design reduces flame exposure time. |
Skill Level | Higher skill required; precise solder application and heating technique are essential. | Easier to use; lower skill needed as the pre-solder simplifies the process. |
Performance | Depending on the solder and conditions, it can achieve pressure ratings up to PN25. | Rated up to PN16. |
Aesthetics | Almost seamless look against the Copper Tube it is installed with. | Almost seamless look against the Copper Tube it is installed with. |
Maintenance and Reusability | Not intended for reuse; connections are permanent once installed. | Permanent fittings that are not reusable after installation. |
