WRAS approved end feed long radius 90 degree bend in 15mm and 22mm. Premium copper fitting for clean, sweated joints on domestic and commercial plumbing installations. Available individually or in boxes of 25.
These end feed long radius 90 degree bends are WRAS approved copper fittings designed for use on copper pipework in domestic and commercial plumbing systems. Available in 15mm and 22mm sizes, they accept standard copper tube and are joined by soldering in the conventional end feed method. The long radius design reduces flow restriction compared to a standard elbow, making these 90 end feed fittings a better choice wherever pressure drop or water velocity is a concern.
End feed fittings are the preferred choice for experienced plumbers and heating engineers who want clean, low-profile joints with complete control over the amount of solder used. There are no pre-loaded solder rings to worry about — you apply the solder yourself, which means consistent joints when you have the technique dialled in. These fittings are well suited to tight or concealed runs where a neat finish matters.
WRAS approval means these fittings have been tested and assessed for use in contact with drinking water systems in the UK. That approval is a requirement on many commercial and public sector jobs, and increasingly expected on quality residential installs too. If a building inspector or facilities manager asks for documentation, WRAS-approved fittings give you something solid to point to.
Where These 90 End Feed Fittings Are Used
Long radius bends see the most use in central heating pipework, domestic hot and cold water systems, and commercial plumbing installations where the pipe run needs to change direction cleanly. The extended sweep of the long radius bend is particularly useful on flow and return runs for radiator circuits, where a tight elbow would create unnecessary turbulence. In concealed pipework — inside stud walls, beneath floors, or within duct runs — the longer bend radius also reduces the risk of stress on the pipe at the joint.
Sizing and Pack Options
Both 15mm and 22mm sizes are available, covering the two most common copper pipe diameters used in UK plumbing. The 15mm size is the standard for branch and final connection work, while 22mm is the typical choice for main distribution runs and boiler connections. Fittings can be purchased individually for small jobs or in boxes of 25 for ongoing work or a full installation — buying in bulk saves handling time and keeps your van stocked without frequent reordering.
These are premium quality copper fittings, machined to consistent tolerances so the tube fits properly and the solder flows evenly around the joint. Poor-quality end feed fittings often have loose tube fit or inconsistent internal bore dimensions, which causes cold joints or callbacks. These are not that sort of fitting.
Pro Tip: With long radius bends, always dry-fit the run before soldering to confirm the sweep direction is correct, as the extended profile can catch you out in confined spaces where a standard elbow would have sat flush.
These end feed long radius 90 degree bends are used across domestic and commercial plumbing installations wherever copper pipework needs to change direction by 90 degrees. Typical applications include central heating flow and return circuits, hot and cold water distribution pipework, boiler connections, and concealed pipe runs within walls and floors. The long radius profile makes them particularly well suited to high-velocity or pump-driven systems where minimising flow resistance is worthwhile.

Not suitable for: Not suitable for use with plastic or push-fit pipe systems without an appropriate copper liner and adaptor. Not rated for steam or high-pressure industrial applications.
Clean the outside of the copper tube and the inside of the fitting socket using wire wool or emery cloth until the surfaces are bright. Apply a thin, even coat of flux paste to both mating surfaces before assembling the joint.
Push the tube fully into the fitting socket, then apply heat with a blowtorch evenly around the joint until the flux begins to sizzle and the copper reaches soldering temperature. Touch lead-free solder wire to the mouth of the socket and allow capillary action to draw the solder into the joint. Remove heat as soon as solder flows fully around the socket rim. Allow to cool naturally before disturbing the joint.
Cut the copper tube squarely using a pipe cutter and remove any burr from the cut end
Clean the outer surface of the tube end and the inner socket of the fitting with wire wool or emery cloth until bright
Apply flux paste to the cleaned tube end and inside the fitting socket
Assemble the joint and push the tube fully home into the fitting socket
Apply heat evenly around the joint using a blowtorch, keeping the flame moving to avoid hot spots
Touch lead-free solder to the socket mouth when the fitting reaches temperature and allow capillary action to draw it in
Remove the flame once solder appears fully around the socket rim, then leave the joint to cool undisturbed
What does WRAS approved mean for these end feed fittings?
WRAS approval means the fittings have been independently tested and assessed as safe for use in contact with drinking water systems in the UK. On commercial, public sector, or new-build residential jobs, WRAS-approved fittings are often specified as a requirement rather than a preference.
What is the difference between a long radius bend and a standard 90 degree elbow?
A long radius bend has a gentler, wider sweep than a standard elbow. This reduces turbulence and flow resistance at the change of direction, which is beneficial on pumped systems or anywhere water velocity is higher. It also puts less stress on the pipe at the joint in concealed or buried runs.
Can I use these fittings with a solder ring or Yorkshire-type fitting on the same run?
Yes, end feed and solder ring fittings are fully compatible on the same copper pipework system. They connect to the same standard copper tube and are joined using the same soldering process. The only difference is that end feed fittings require you to apply your own solder, while solder ring fittings have a pre-loaded ring inside the socket.
These long radius 90 degree bends are manufactured from copper to consistent machined tolerances, ensuring reliable tube fit and even solder flow around the joint socket. The fittings carry WRAS approval, confirming suitability for use in cold and hot water supply systems in contact with drinking water. Both 15mm and 22mm sizes conform to standard UK copper tube dimensions to BS EN 1057.
