Pre-Soldered Copper 90° Elbow Fittings | Microbore & Standard Sizes 6.35–273mm

Match the inner diameter (ID) of the fitting to the outer diameter (OD) of your copper pipe. For example, a 15mm ID fitting is typically used with 15mm OD copper tube. Common microbore sizes include 6.35mm (1/4"), 8mm, 9.52mm (3/8"), and 12.7mm (1/2"). Always verify your pipe's OD before ordering. If you're unsure, contact us to confirm.

Wall thickness affects pressure rating and durability. For standard residential plumbing and heating, 0.8mm–1mm is generally sufficient for smaller diameters. For larger diameters or higher-pressure applications, 1.5mm–2mm or thicker is typically recommended. Contact us to confirm the right wall thickness for your specific application.

Pre-soldered (also called solder-ring or Yorkshire-type) fittings have a ring of solder pre-loaded inside the fitting socket. When you heat the fitting with a torch, the solder melts and flows into the joint automatically, creating a reliable, leak-free connection without needing to feed additional solder wire. This makes them faster and more consistent to install compared to end-feed fittings.

Copper is naturally corrosion-resistant and is generally suitable for outdoor and damp environments. However, in areas with aggressive soil chemistry or where the fitting will be buried, additional protection such as wrapping or sleeving is typically recommended. Always follow local plumbing codes for buried or concealed installations.

Yes. These fittings are designed for use with standard copper tube conforming to EN 1057 (R220/R250) and equivalent ASTM B88 specifications. Both metric and imperial-equivalent sizes are available. Always verify the tube standard used in your region before purchasing.

Pressure ratings vary by diameter and wall thickness. Smaller microbore fittings (6.35–15mm) with 0.8–1mm walls are typically rated for standard domestic water and heating pressures (generally up to 10–16 bar depending on temperature). Larger diameters require thicker walls for equivalent pressure ratings. Contact us to confirm ratings for your specific size and application.

Yes. Pre-soldered copper 90° elbows are commonly used in underfloor heating manifold connections, radiator tails, and microbore heating circuits. The smaller sizes (6.35mm–12.7mm) are particularly well-suited for microbore heating systems where tight bends and compact connections are needed.
