High Pressure Hose Assembly

High pressure hose assembly consists of an inner tube, a layer of reinforcement and a cover. The components must be compatible with the fluid media used.

Hose selection must assure that the published maximum working pressure of both the hose and the Fittings is equal to or lower than the maximum system pressure. Surge pressures and peak transient pressures must also be below the hose’s limit.

Technical parameters

The selection of a suitable high pressure hose assembly is dependent on a number of factors, such as the system pressure, ambient temperature, the fluid used and the bending radius. These parameters must be carefully considered when choosing a product.

In order to ensure the integrity of a Hose Assembly, it is important to inspect all components for defects such as blisters, cuts, loose covers, kinks or obstructions. In addition, the hose must be properly secured to prevent mechanical stress and accidental displacement.

It is important to follow the manufacturer's guidelines for working pressures and temperatures to avoid premature failure due to temperature. For example, a high-pressure hose that is operated outside of its temperature range may become brittle or lose flexibility and can cause system damage.

It is also important to consider the routing of a hose assembly to reduce inherent problems such as kinking, tensile loads or vibration. In addition, the hose should be properly insulate and protected from hot objects and heat sources.


The use of high-pressure hose assemblies can vary depending on the specific application. They are often used in a variety of industrial applications, including automotive manufacturing, mining, and construction. They can also be used for powering hydraulic equipment. They can withstand extreme working pressure and have a low weight.

Choosing the right hose for an application is important to ensure safe and proper operation. There are several factors to consider, including the type of media that will be transported and the maximum working pressure. It is also important to choose the correct hose for the temperature of the environment.

Using a hose that is too thin can cause a leak, which can be dangerous. In addition, it is important to check the hose for damage before each use and know its capabilities. For example, the hose should be able to withstand dynamic pressure, which includes shocks, pulses, and temperature changes. It should also have a small bend radius to prevent kinking.

Usage precautions

Whenever you’re using a high-pressure hose assembly, it is crucial to know its limits and the proper use. Failure to follow these precautions can lead to dangerous accidents that could end up causing significant injury and property damage.

For example, if a hose fails while in use, it could release pressurized fluid or gas, which can cause serious injuries to personnel in the immediate vicinity. If the fluid or gas is flammable, it could also lead to a fire that can damage equipment and cause severe property damage.

The best way to prevent this from happening is to carefully inspect the hose and its end fitting connections before each use. Look for any signs of abrasion, rust or corrosion and ensure that the hose has a suitable pressure rating for your application. You should also be sure that the hose is compatible with the media you’re transporting and that the fittings are secure and leak-free.


A high-pressure hose assembly has many components that must be maintained and replaced as necessary. Failure to do so may result in the dangerous release of hazardous liquids or gases and damage property or equipment. Personnel injury is also a possibility.

Regular visual inspections of the hose and its fittings can help identify signs of deterioration or malfunction. In addition, the hose should be properly positioned and secured to ensure that it will not be subjected to excessive bending or twisting.

A hose assembly's maximum pressure is also important to know, and the manufacturer may have guidelines for minimum bend radius, proper fitment and other requirements that must be followed. It is also important to follow recommended installation procedures such as using a torque wrench or the traditional 'number of turns past hand tight'. Using a hydraulic pressure test can help detect small leaks and cracks that might otherwise go unnoticed. The test pushes the hose to its limit and shows any areas of weakness or leakage.
