CONNECTOR PORCELAIN 5-18 GAUGE

Most connectors have a gender i.e. the male component, called a plug, connects to the female component, or socket. A connection may be removable (as for portable equipment), require a tool for assembly and removal, or serve as a permanent joint between two points. An adapter can be used to join dissimilar connectors. Connectors are commonly used in plumbing and electromechanical assemblies.

A gauge is a device used to make measurements or in order to display certain dimensional information. A wide variety of tools exist which serve such functions, ranging from simple pieces of material against which sizes can be measured to complex pieces of machinery. Depending on usage, a gauge can be described as "a device for measuring a physical quantity", for example "to determine thickness, gap in space, diameter of materials, or pressure of flow", or "a device that displays the measurement of a monitored system by the use of a needle or pointer that moves along a calibrated scale".
