This listing is for a Pack of 2 To prepare copper pipe for end feed fittings, cut it square, deburr the edges, clean the pipe end and fitting socket to bright metal with an abrasive pad, and apply a thin layer of flux before assembly. Ensure there is zero standing water inside the pipe. Even a single drop of water turning to steam during heating will blow the molten solder out of the capillary gap. An end feed stopend (also known as a copper end cap or capillary blanking cap) is a solid copper fitting used to permanently seal or terminate the end of a copper pipe run. Like other end feed fittings, it has a plain socket that requires solder wire to be fed manually into the joint when heated with a torch.
