The selection of the right hydraulic hose for your needs should be based on several factors. In this article, we’ll review some of the components of hydraulic hoses, their sizes, and their strengths and durability. So, go now and read on for more information. When choosing the right hydraulic hose, remember to match the size and thread end to the proper coupling. It is important to choose the correct coupling to ensure leak-free sealing. You can choose either permanent type or field-attachable couplings.
Components
Hydraulic hoses have several components that make them useful for specific applications. Their material and pressure ratings will determine the type of hose and couplings that will work best with the particular application. Other components that will determine the type of hose are the couplings, ends, and volume and velocity of delivery. Here are some tips on identifying the best hose for your particular application. Listed below are some components of hydraulic hoses.
Fitting covers protect the hose’s reinforcing material and tube. These fittings feature a socket that extends into the inner tube and a stem that goes over the outer cover. The connecting end connects the hose to other components. It is essential to select the right hydraulic hose for your specific application because this will help to prevent a malfunction or blowout of the hose. Here are some important components of hydraulic hoses:
The outer cover acts as a protective layer and should be compatible with the operating environment. A good outer cover is made from material that reflects the ambient temperature and is resistant to abrasion. Ideally, the hose should be able to withstand high temperatures without experiencing any kinks. If the hose is exposed to an environment that is hot, it will reduce its service life by at least 80%.
Flexible hoses are easier to route and install than rigid tubing. They reduce vibration, dampen pressure surges, and allow movement between parts. Increasing customer demands have forced hose manufacturers to make their products stronger and more durable. Many new flexible hoses can withstand higher pressures, higher temperatures, and a wide range of fluids. For this reason, the market for hydraulic hoses is growing.
Sizes
When choosing a hydraulic hose, it is important to determine the inside diameter of the piping. The inside diameter will determine the amount of flow the hose can deliver. If the pressure is high enough, a larger inside diameter can be chosen. However, high velocities can cause noise and heat, which decreases efficiency. When choosing the proper hose size, you should consider the following factors:
First, you must determine the amount of pressure you need to transmit. This will determine the diameter and length of the hose. The length of a hydraulic hose depends on its flow rate. The size of the hose depends on its diameter and the amount of pressure the hose must transport. It should be as long as the piping supports the pressure. In addition, the length should be appropriate for the fitting’s size.
The next consideration is the temperature. The temperature outside and the temperature inside the hose will affect the life of the hose. Extremely high or very low ambient temperatures can damage the reinforcement materials in the hose, which will reduce its service life. Similarly, very low ambient temperatures can result in premature failure of the hydraulic hose. To avoid these problems, make sure you choose the right size hose. Don’t take any chances – consult a hydraulic hose manufacturer for the correct sizing.
In addition to the outside diameter, another important factor is the inside diameter of the hose. Increasing the hose length increases the pressure and head loss due to friction. The inner diameter of the hose, also known as the dash size, is the industry standard. A dash size of a hydraulic hose is usually equivalent to sixteenths of an inch. For example, “-1” means an inner diameter of one sixteenth of an inch, while a “-2” is equivalent to two sixteenths of an inch. The “-3” indicates the inside diameter is three eighths of an inch. Similarly, a -10 tube will have an outside diameter of ten sixteenths of an inch, or five eights of an inch.
Strength
There are different standards for the strength of hydraulic hoses. Typically, a hose has a higher pressure rating when manufactured to a specific length. In addition, the material used to manufacture the hose is typically thicker, with additional layers of reinforcing wire. Regardless of the type of hose you choose, make sure it meets the required pressure rating. Hoses should also be protected from extreme temperature changes by using a heat-resistant sheath.
A good hose has the ability to handle high pressure, but if it is not coupled with the right fittings, it will do little good. The weakest points in any hydraulic system are the fittings. Any joints, angles, seams, or other weak spots can lead to system failure and reduce a hose’s capacity. Proper fittings will help your hoses function at their highest capacity and provide strength to your hydraulic system.
Another important factor to consider when choosing the right hose for a particular application is the temperatures. When used in a hydraulic system, fluid temperatures can vary by several hundred degrees celsius.
Durability
There are a number of factors that affect the durability of hydraulic hoses. They are subject to a variety of harsh conditions, including ozone and direct sunlight, which can degrade the rubber compounds and cause cracks. In addition to constant exposure to the elements, hydraulic hoses frequently come into contact with other equipment parts and other environmental hazards, which can erode the rubber cover and weaken the reinforcing layers of the hose. In forestry applications, hoses frequently brush against tree branches and logs. These factors make the durability of hydraulic hoses a top priority.
There are a variety of factors that influence the durability of hydraulic hoses, including the construction and composition of the rubber. Different rubber compounds contain five to 30 ingredients, each of which plays a specific role. Although there are industry standards, the actual composition of a rubber compound can differ, but the basic structure remains the same. For instance, advanced rubber formulations can enhance the abrasion and fatigue resistance of the hose. Durable rubber suppliers test their materials to meet specifications for durability.
Using hydraulic fluids outside of this temperature range can result in premature failure of the hose. Furthermore, higher temperatures can cause the material to harden while lower temperatures can lead to cracking.
The most common reason for the failure of hydraulic hoses is abrasion. These hoses often rub against other objects and surfaces, and even small amounts of friction can lead to abrasion. Because of these factors, it’s important to consider the abrasion factor when choosing the routing of hydraulic hoses. Avoid locations where the hoses are subjected to high-abrasion, and ensure that they are routed to avoid areas with hot air.

Fluid compatibility
The choice of a suitable hydraulic hose depends on several factors. Its pressure, temperature, ambient temperature, and special requirements should all be taken into consideration. In addition, legal regulations must be followed. If there are any doubts, contact the manufacturer for recommendations. If you do not find your specific fluid on the compatibility chart, the technical service department at Motion & Flow Control Products in Wickliffe, Ohio, can help you out.
A hose should be compatible with the fluid used in its original assembly and application. Various parameters are taken into consideration, including pressure, material/media, environment, end connections, and delivery. Fluid compatibility of hydraulic hoses is essential to maximizing their lifetimes. Proper hose selection can save operational costs and increase revenue. Listed below are some of the main factors to consider. These criteria will ensure that your hydraulic hose is suitable for your particular requirements.
A hydraulic hose’s temperature rating is crucial for many reasons. It will determine the maximum operating temperature for your hose. Fluids below this temperature can degrade quickly, causing cracks and failure. Fluids that are too hot may also cause hoses to break down into by-products that damage elastomers and other materials. It’s therefore important to check the temperature range of your hose before purchasing one.
In general, couplings must match the hose. A properly matched coupling ensures a leak-free seal and is easy to install. Field-attachable couplings are more economical and less complicated to install.
