Hydraulic Hoses Key Terms

Understand the technical terms relating to hydraulic hoses

By Howard Robertson

A hydraulic hose is an important component of a hydraulic system that carries hydraulic fluid from one component of the system to another component. Selection of hydraulic hoses depends upon various application factors such as operating temperature, system pressure and system fluid.

While interacting with the suppliers of hydraulic hoses, you will come across various technical terms. This guide will explain some technical terms related to hydraulic hoses, such as braided hoses, hose clamps, PSI and SAE standards.

Braided hoses

Some hydraulic hoses have a reinforcement woven over the tubing of the hose. This adds to the strength of the hose material and helps to sustain more pressure. Manufacturers of hydraulic equipment and supplies use textile fibres and metal wires as reinforcements in braided hoses.

Hydraulic hose accessories

For safe and efficient functioning of a hydraulic hose, you will need to use hydraulic accessories. Commonly used hydraulic hose accessories are clamps, sleeves, support coils and protection springs.
Try: You can browse through a description for each type of accessory at HoseXpress, a reputable distributor of hoses and hose accessories.

Hose clamps

A hose clamp (also known as hose clip) is the most frequently used hose accessory. Hose clamps are useful for attaching and sealing hoses with mating parts, such as other hoses, pipes and fittings. These clamps come in various types, including screw clamps, spring clamps and wire clamps.

Hydraulic pressure

In a hydraulic system, the system fluid exerts pressure on the components, such as hoses, valves and tanks. This pressure existing in a hydraulic system is known as hydraulic pressure. For selection of hydraulic hoses, estimating maximum hydraulic pressure is very important.

PSI (Pressure per Square Inch)

PSI is the unit of measurement for the hydraulic pressure in a hydraulic system. One PSI is the pressure resulting from a force of one pound to an area of one square-inch.
Try: SensorsONE Ltd, a knowledge resource for pressure monitoring instrumentation, provides the explanation for the term PSI.

Viscosity

Viscosity indicates the resistance of the fluid to flow. The more viscous the liquid, the lower its flowing rate. Viscosity of the fluid is an important parameter for the design and selection of hydraulic hoses.
Try: For the definition of viscosity, you can read through the glossary of technical terms at IVEK Corporation, a supplier of precision liquid metering and dispensing systems.

SAE standards

SAE International, a reputable association in the field of automotive engineering, provides standards for hydraulic hoses. These standards assure safe and optimal usage of hydraulic hoses in different working conditions.
Try: For information about various SAE standards, such as SAE 100R1, SAE 100R2 and SAE 100R10, read through information at Hydraulics & Pneumatics, a magazine for the hydraulics and pneumatics industry professionals.

Hydraulic hose failures

While using hydraulic hoses, you must be aware of various hydraulic hose failures and remedies for such failures.
