Hydraulic hose are made from a flexible material that can withstand high pressure and not break. They have a higher burst pressure than most other types of rubber hoses and are used in the oil, gas, and mining industries. The materials that can be used to create these hoses include:

Plastic: Plastic is the least expensive option and it is good for applications that need a hose to move or flex.

Rubber: Rubber has a higher resistance than plastic, so it is good for applications with more pressure, namely hydraulic systems.

Fiberglass: Fiberglass has the best resistance, so it should only be used in extreme circumstances where there are high pressures present.

Steel Wire Reinforced Plastic (SWR): This material pairs rubber or plastic with steel wire for strength. It can withstand higher pressures than other materials because of its steel wire content, but it costs more than other materials. 

Hydraulic hoses come in many different types and materials which is important to take into account when selecting what to use. For example, they have different diameters for connection type, pressure ratings, and flexibility. Hose selection should be based on the needs of the equipment being used as well as what is around it.  When operating under high pressure, these hoses need to be made from a flexible material that can withstand high pressure without breaking or rupturing. This means that the material must be strong, durable, and flexible enough to withstand the rigors of everyday use while not deteriorating over time to the point that it leaks or bursts.

They are fitted with several valves to change the direction of the fluid flow and to regulate the output. Hydraulic hoses are the lifeblood of the machines that are used in transportation, agriculture, construction, manufacturing, and oil fields. Using these hoses in these industries helps with production efficiency because they require fewer outside power sources. These hoses are also used in a wide range of industries including automotive, aerospace, and construction. 

These hoses are composed of three parts: the metal couplings on both ends, and the rubber hose in between. The metal couplings are threaded so that pressure can be built up inside the hose while it is attached to machinery. The rubber hose allows for flexibility and prevents ruptures due to high pressure.
