The pressure rating depends on wall thickness and construction, both of which are related to the size of tubing. A variety of different tube fitting sizes are used, depending on the application requirement. Hence, the pressure rating of a tube in a particular operation varies based on these factors.Mostly manufactured from 316 stainless steel or brass, single ferrule tube fittings are available in sizes ranging between 116 to 2 inches. These fittings are designed in a manner that makes it almost impossible to install them incorrectly. These have fewer pieces than most other types of fittings.
