End Feed Copper Elbow Fittings | 6mm–133mm | WRAS Approved Plumbing Bend

Match the inner diameter (ID) of the elbow to the outer diameter (OD) of your copper pipe. For example, a 15mm copper pipe typically requires a φ15mm end feed elbow. If you are working with imperial pipe, note that 1/2" pipe is approximately 15mm (≈0.59") and 3/4" pipe is approximately 22mm (≈0.87"). When in doubt, measure your pipe OD and select the closest matching elbow ID from the variant options above.

Thicker walls generally provide greater pressure resistance and durability. For standard residential plumbing and heating systems, 1mm wall thickness is typically sufficient. For higher-pressure or industrial applications, 1.5mm or 2mm walls are generally recommended. Check your system's pressure rating and consult local plumbing codes if unsure. Note that available wall thicknesses vary by diameter — see the variant selector for options specific to your chosen size.

Copper is naturally resistant to corrosion and performs well in most outdoor and damp environments. However, in highly acidic soils or aggressive water conditions, additional protection such as pipe lagging or sleeving is generally recommended. These fittings are not intended for direct burial without appropriate protection. For outdoor exposed installations, standard copper weathering behavior (patina formation) is expected over time.

These are end feed (capillary) fittings — they connect by soldering (brazing) onto copper pipe. They do not use threaded connections. The fitting slides over the pipe end and is secured with solder, creating a leak-free joint. They are compatible with standard copper tube conforming to EN 1057 dimensions. If you need a threaded connection, you would require a different fitting type (e.g., a solder-to-thread adapter).

WRAS (Water Regulations Advisory Scheme) approval indicates the fittings have been tested and certified as safe for use in contact with drinking water under the UK Water Supply (Water Fittings) Regulations. This certification is generally accepted as meeting equivalent standards in many other markets. It is an important compliance consideration for potable water plumbing installations and may be required by local building codes or inspectors.

End feed copper elbows are commonly used in central heating and hot water systems. For gas applications, always verify that the specific fitting and installation method comply with local gas safety regulations and standards — in most cases, a qualified gas engineer should perform gas line work. For central heating circuits, these fittings are generally suitable when installed with appropriate solder and flux for heating applications.

We offer pack quantities of 1, 2, 5, 10, 20, and 100 pieces. For a single repair or small DIY job, 1–2 pcs is typically sufficient. For a bathroom or kitchen remodel, 5–10 pcs covers most runs. For larger plumbing projects or trade use, the 20 or 100-piece packs offer better value per unit. The per-piece cost decreases at higher quantities, so stocking up makes sense for ongoing work.
