Hydraulic Hose

A hydraulic hose is a type of hose that is specifically designed to be used with hydraulic power equipment. These types of hoses have a wide variety of uses. Common applications include heavy duty tools, automobiles and more. These hoses are also used in heavy manufacturing. They can be found in a wide variety of applications such as bulldozer, the landing gear of an aircraft, the loading ramp on a cargo ship or even a robotic arm in a manufacturing facility. A hydraulic hose is a critical part of any machinery that uses liquid pressure (usually natural or synthetic petroleum products or water) to assist in powering or controlling the machine. These hoses are designed to be leak resistant and to work in extreme conditions.

A hydraulic system is similar to the human circulatory system. The hoses are like the veins and the hydraulic fluid is like the blood. As long as the fluid maintains the correct pressure and flow everything will work properly. If the fluid pressure drops, often due to a blockage or leak, in the machine is unable to function. Therefore hydraulic hoses must be able to withstand great amounts of pressures without leaking and must be able to take significant amounts of heat or cold, depending on the environment they are designed to operate in. Some hydraulic hoses that are designed to operate at temperatures easily exceeding 300°F while other hoses are designed to operate in extreme low temperatures.

The high operating pressure and extreme temperatures mean the hoses require special couplings to connect to the device. These couplings are often made out of a combination of titanium and brass and carbon fiber. Usually they have been specially treated to withstand extreme temperatures. There are also hydraulic hoses that are capable of withstanding temperatures in the range of -30° below zero the hydraulic hoses come equipped with special cold-weather installation that will allow them to keep the hydraulic fluid flowing smoothly so that any given machine can stay in operation.

Most common hydraulic hoses are constructed with industrial strength rubber. The hoses come in a wide variety of sizes, which can be as big as a fire hose or as small as heavy gauge copper wiring. The size of the hydraulic hose is determined by the size of the machine as well as the amount of hydraulic fluid each hose will have passing through it at any given time.

Rubber is the most common hose construction material because of its flexibility and low cost. For situations that require extra strength, hydraulic hoses can be made from braided stainless steel, titanium or a combination of both. These metal hydraulic hoses are used when the machinery will be subjected to extreme conditions on a continuous basis. These metal hoses are especially suited for jobs in which the liquid that passes through is at a very high pressure. The downside to these extra strong metal hoses is that they do not flex as well as rubber hoses and are prone to breakage when bent beyond their limit.
