Abstract
Fittings made of copper, brass, red brass or steel are provided with an inside coating of a flux and a solder layer. By this technique, the soldering process is simplified, damages caused by overheating of the flux are avoided and the amount of the solder used is reduced.
Claims21
A fitting for brazing or soldering metal tubes, comprising:
- a cylindrical outer fitting body having an inside cylindrical wall;
- a braze or solder cylinder at least partially within said cylindrical outer fitting body, said braze or solder cylinder attached to said inside cylindrical wall of said outer fitting body;
- a thin braze or solder ring attached to an end of said braze or solder cylinder, said braze or solder ring being located within said fitting body;
- and
- a thin layer of flux located between said fitting body and said braze or solder cylinder, whereby a metal tube whose end is to be soldered or brazed is fitted into said cylindrical outer fitting body having said braze or solder cylinder attached thereto, and the brazing or soldering is performed by heating the fitting body with the metal tube therein, such that the fitting body acts as a coupling.

A method for producing a fitting for brazing or soldering metal tubes, comprising:
- coating a thin walled solder or braze cylinder with a flux layer, and
- pressing said flux coated cylinder against an inner wall of a cylindrical fitting body to attach the flux coated solder or braze cylinder to the fitting body, whereby a metal tube whose end is to be soldered or brazed is fitted into said cylindrical outer fitting body having said braze or solder cylinder attached thereto, such that the fitting body acts as a coupling.
A fitting for brazing or soldering metal tubes, comprising:
- a cylindrical outer fitting body having an inside cylindrical wall;
- a braze or solder cylinder at least partially within said cylindrical outer fitting body, said braze or solder cylinder attached to said inside cylindrical wall of said outer fitting body;
- and
- a thin layer of a flux located between said fitting body and said braze or solder cylinder,
- wherein the fitting body is made from at least one material chosen from the group of copper, brass, red brass or steel, whereby a metal tube whose end is to be soldered or brazed is fitted into said cylindrical outer fitting body having said braze or solder cylinder attached thereto, and the brazing or soldering is performed by heating the fitting body with the metal tube therein, such that the fitting body acts as a coupling.
2 more elements
A fitting for brazing or soldering together two metal parts, comprising:
- an outer fitting body;
- a first braze or solder cylinder and a second braze or solder cylinder, wherein each of said first and second braze or solder cylinders are at least partially within said outer fitting body;
- a first thin braze or solder ring attached to an end of said first braze or solder cylinder, a second thin braze or solder ring attached to an end of said second braze or solder cylinder, said first and second braze or solder rings being located within said fitting body;
- and
- a thin layer of a flux located between said fitting body and said first and second braze or solder cylinders, whereby a first metal part whose end is to be soldered or brazed is fitted into a first end of said cylindrical outer fitting body having said first braze or solder cylinder attached thereto, and a second metal part whose end is to be soldered or brazed is fitted into a second end of said cylindrical outer fitting body having said second braze or solder cylinder attached thereto, such that the fitting body acts as a coupling for the two metal parts.
