This guide is for plumbers and heating engineers working with copper pipe systems. The Prima Classic Endfeed Long Radius Bend 90' 22mm offers a reliable and cost-effective solution for changing pipe direction by 90 degrees. While it provides excellent value, users should ensure proper soldering techniques are applied for optimal performance. This pack of ten 22mm fittings is manufactured from copper to EN 1254 standard, WRAS approved for drinking water, and designed for easy installation via endfeed (capillary) soldering.

WRAS approval signifies that the fitting has been independently checked and meets the high standards set by the Water Regulations Advisory Scheme, ensuring it is safe for use with drinking water in the UK.
These fittings are suitable for low-pressure gas installations, but always ensure compliance with local regulations and standards for gas work.
A long radius bend has a gentler curve, resulting in less resistance to fluid flow and lower pressure loss compared to a short radius bend, which has a tighter curve.
Use a pipe cleaning brush, emery cloth, or abrasive pad to remove any dirt, grease, or oxidation from the end of the copper pipe and the inside of the fitting socket.
Use a lead-free solder specifically designed for plumbing applications, along with a compatible flux. Ensure the solder is suitable for the intended application (e.g., water or gas).
Yes, provided the system operates within the pressure and temperature limits for which these copper fittings are rated and WRAS approval applies.
Ensure the pipe and fitting are clean and fluxed correctly. Check that adequate heat has been applied to the fitting, not just the solder. Ensure the pipe is fully inserted.
The joint may not have been heated sufficiently, or the pipe may not have been fully inserted. Re-heat the joint and apply more solder, or consider re-making the joint if the issue persists.
Clean the oxidized area thoroughly with pipe cleaning wool or a wire brush before applying flux and proceeding with soldering.
