The end feed end cap is one of those fittings that does exactly what it says and asks nothing in return. You solder it on, the pipe is terminated, job done. Available in 8mm, 10mm, 15mm, 22mm and 28mm, these WRAS approved end feed end caps cover the copper pipe sizes you’ll encounter on the vast majority of plumbing jobs across domestic, commercial and light industrial settings.
WRAS approval matters here. It confirms the fitting meets Water Regulations Advisory Scheme requirements for use in contact with potable water, so there’s no question mark hanging over it when you’re working on drinking water systems. Specifiers, building control and end clients increasingly ask for WRAS approved fittings as standard, and these tick that box without any fuss.
End Feed End Cap Applications on Site
End feed fittings suit plumbers who are confident with a blowtorch and flux. The fitting itself has no integral solder ring, so you apply flux, push the cap onto the pipe end, apply heat and feed solder in at the joint mouth. It gives you full control over the solder quantity, which experienced plumbers often prefer. The result is a clean, permanent termination that won’t budge.
Whether you’re capping off a redundant supply, blanking an unused port on a manifold, or tidying up during a bathroom or kitchen refit, these fittings handle it cleanly. At this price point, keeping a small stock of each size on the van makes sense. Running out of a 15mm end cap is one of those small annoyances that adds up over a week.
These are straightforward copper end feed fittings made to perform reliably in standard pressurised pipework systems. No complications, no adapters needed, just a solid solder joint and a terminated pipe.
Pro Tip: Always clean the pipe end and the inside of the cap with wire wool or emery cloth before fluxing, even on new copper: a contaminated surface is the most common reason an end feed joint weeps under pressure.
End feed end caps are used wherever a copper pipe run needs to be permanently terminated. Common situations include capping redundant supplies during kitchen and bathroom refits, blanking off pipework during phased installations, and closing unused tees or ports. They are used by plumbers and heating engineers across domestic housing, commercial fit-outs and light industrial pipework, wherever standard copper tube to BS EN 1057 is in use.

Key Features
WRAS approved for potable water use
End feed design for full solder control
Available in five standard sizes
Suitable for pressurised pipework systems
Permanent watertight termination
Not suitable for: Not suitable for use with plastic or push-fit pipe systems. These are end feed fittings requiring soldering and are not compatible with compression or press-fit installation methods.
Clean the outside of the pipe end and the internal bore of the end cap using wire wool or emery cloth until both surfaces are bright copper. Apply a thin, even coat of flux to both surfaces, push the cap fully onto the pipe, and apply heat evenly around the joint with a blowtorch. Feed solder into the joint mouth until a bright ring appears all the way round, then remove heat and allow the joint to cool undisturbed before wiping off excess flux.
Cut the pipe square and remove any burrs with a deburring tool or file
Clean the pipe end and the inside of the cap with wire wool or fine emery cloth until the copper is bright
Apply flux paste to both the pipe end and the inside of the cap
Push the cap fully onto the pipe end
Apply heat evenly around the fitting with a blowtorch until the flux begins to bubble
Feed solder wire into the joint mouth until a complete bright ring of solder appears around the cap edge
Remove heat and allow the joint to cool naturally without disturbing it
Wipe away excess flux residue with a damp cloth once cool
Are these end feed end caps suitable for use on drinking water systems?
Yes. These fittings carry WRAS approval, which confirms they meet the requirements for use in contact with potable water. They are suitable for use on mains cold water and domestic hot water supplies.
What is the difference between an end feed fitting and a solder ring fitting?
An end feed fitting has no pre-loaded solder inside it. You apply the solder yourself during the joint-making process, feeding it in at the mouth of the fitting once the copper is up to temperature. A solder ring fitting has a ring of solder pre-loaded inside, which melts when heat is applied. End feed fittings give you more control over solder quantity and are generally preferred by experienced plumbers.
Can I use these end caps on microbore pipe?
Yes, the 8mm and 10mm sizes are suitable for microbore copper pipe as used in central heating systems. Make sure you select the correct size to match your pipe outside diameter.
Manufactured from copper to suit standard BS EN 1057 copper tube, these end feed end caps are WRAS approved for use in cold and hot water supply systems. End feed construction means no integral solder ring, requiring the application of lead-free solder during installation. Suitable for use in standard domestic and commercial pressurised pipework at typical system working pressures.
