Brass Compression Fittings are used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. In instances where two pipes made of dissimilar materials are to be joined, the fittings will also be made of Brass or more compatible materials appropriate for the connection. Compression fittings for attaching tubing (piping) commonly have ferrules in them.

Brass Compression fittings are also used extensively for hot and cold water faucets (taps) and toilet stop valves; compression fittings are well suited to this application, as these valves are usually located in confined spaces where copper pipe would be difficult to solder without creating a fire hazard. Compression fittings are the industry standard for chemical, oil and gas, R&D, Bio-tech, and the semiconductor industry. They are used due to their ability to provide leak tight seals. These fittings can be remade. The compression fitting is composed of an outer compression nut and an inner compression ring; or ferrule that is usually made of brass. Ferrules vary in shape and material but are most commonly in the shape of a ring with beveled edges and they are most commonly made out of brass or according to the pipe material. To work properly, the ferrule must be oriented correctly; typically the ferrule is fitted such that the longest sloping face of the ferrule faces away from the nut.
