Hydraulic hose fittings are very useful when it becomes necessary to connect various conductors such as tubes, pipes, and hoses in a hydraulic system. Most of these connections will have a male and female component to accommodate the connection and will assist with the process of containing and directing the flow of fluid; while also preventing any leakages and maintaining pressure in the lines. Various types of fitting allow the designer to change the flow of the fluid, to split the flow of the fluid, or to elevate the lines. Below we’ve compiled a hydraulic hose fittings chart describing some of the more common fitting sizes and types currently in use by pipe fitters and other professionals.
