The "PRE SOLDERED PLUMBING FITTING" IS A COPPER PLUMBING FITTING WHICH USES THE CAPILLARY ATTRACTION METHOD TO CAUSE SOLDER TO FILL THE GAP, WHICH IS THERE, BETWEEN ANY GIVEN TUBE AND FITTING SOCKET, HENCE ENSURING A PERFECT JOINT ON ALL FITTINGS. THE SOLDER IS PUT IN PLACE ON THE FITTINGS WHEN THEY ARE MANUFACTURED, AND IS FOUND ON THE WALL OF EACH SOCKET. THE SOLDER MENTIONED IS THEN RELEASED WHEN THE FITTING IS HEATED EXTERNALLY, AND THEREBY PROVIDES A PERFECT AND WATERTIGHT JOINT IN A FRACTION OF THE TIME WHICH IT PRESENTLY TAKES. ALL FITTINGS ARE MADE OF COPPER AND RELATE TO ALL STANDARD SIZES, AND TO THE DIFFERENT TYPES OF FITTINGS.
