Hydraulic hose refers to any flexible tubing that allows transport of fluid in a system. Unlike the rigid pipes and tubes required for tight fitting spaces, hydraulic hoses are used where pliability is needed to accommodate movement between two ports. A common application is in the use of a tailgate lift strut on your car or truck. Because it be properly specified and selected for use, here are some things to know about hydraulic hoses.

Construction

A hydraulic hose is constructed of three layers: inner, reinforcement and outer. The inner layer conveys the liquid and must remain flexible while being compatible with its contents. The reinforcement layer contains a coiled wire to resist tearing and fracture. Protective, rigid materials make up the outer layer. The construction type must be specified according to the application. Reinforced types have extra buffer materials in the interior layer. Coiled and/or corrugated hoses allow facilitate expansion and compression without stresses. Articulated hoses are intended for use where easy bending or flexing is necessary. Consult a seller of Hydraulic Hose San Antonio to specify and select the right parts.

Selection

The word “STAMPED” is a useful acronym to track the criteria for choosing the proper hose:

• Size – Inner and outer diameters as well as length are the important factors here.
• Temperature – Hydraulic hoses are often subject to high temperatures.
• Application – The minimum radius bend is a measure of how much the hose can bend or flex while maintaining flow rate.
• Material – Is the material conveyed compatible?
• Pressure – Hydraulic hoses may also be used in operations with high pressures. Choose one with the proper pressure rating.
• Ends – Also known as fittings, this refers to any attachments needed for a particular function.
• Delivery – This involves the quantity of hose and replacement requirements.

Hydraulic hoses are important components of various systems, including ones used in vehicles and industrial machinery. Exposure to high pressures, temperatures and volatile materials demand special attention for correct specification and selection.
