Also known as: end feed coupling, straight coupling, copper coupler, pipe connector, 28mm socket, capillary coupler, solder coupling, endfeed 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.
