The 35mm × 22mm End Feed Reducing Coupler is an external reducer that joins 35mm copper tube to 22mm copper tube in a straight run with a soldered capillary joint. Socket both ends, it fits over the outside of the tube — steps commercial 35mm pipework down to 22mm distribution. Manufactured from copper to BS EN 1254-1 and fits copper tube to BS EN 1057.

Also known as: external reducer, external coupler, external reducing coupler, reducing coupling, reducing socket, copper reducer, pipe size reducer, 35-22mm coupler, capillary reducing coupler, endfeed reducing coupler.

End feed means a capillary joint: clean the tube and fitting, apply flux, heat evenly and feed lead-free solder to the mouth of the fitting until a ring forms. See our guide: How to solder end feed fittings.
