This copper Center CB 22mm end feed 90° street elbow has compact dimensions and a lightweight design for easy handling and installation even where space is limited. Designed with smooth lines to minimise flow restrictions, this fitting is unobtrusive on exposed pipelines. The end feed general range is designed for end-feeding with soft solder or hard solder (brazing alloy). The solder joint is created through the principal of capillary action, when the fitting and tube is assembled and heated to the appropriate temperature, solder becomes molten and is drawn into the gap between tube and fitting for a durably reliable joint.
