There are a number of benefits to choosing the right hydraulic hose. You should consider the following factors when purchasing a hose: Durability, flexibility, abrasion resistance, and ease of routing. In addition, SAE hoses are generally oil resistant, and they can withstand a wide range of temperatures. So, go now and read on to discover the benefits of hydraulic hoses. Here are some of the most important ones. Listed below are a few.
Flexible
Flexible hydraulic hoses are used in a variety of applications, from oil and gas drilling to the transportation of liquids. These hoses are made from helically wound profiled strips, and they are typically interlocked to allow for flexible routing and fitting. Flexible hoses are also used to convey air from surface compressors and water from sprinklers and irrigation systems. They also provide flexible hoses with a number of benefits over rigid pipes, including durability and ease of routing.
The first step in installation is to ensure that the hoses are not subjected to a mechanical load, such as sharp bends. Whenever possible, use the Technical Data Section of the vendor’s catalog to maintain a minimum centerline bend radius. The minimum bend radius is approximately 5 to 8 percent. Whenever possible, install flexible hoses at least 5 percent slack. They must also be protected from excessive temperatures, as they contract and expand with pressure. Fortunately, these hoses can be protected from extreme temperatures by installing shrouds or locating them away from hot areas.
Another factor to consider is the material of the inner tube. In most cases, hydraulic hoses are made from rubber, which has multiple layers of reinforcement to ensure it can withstand high pressures. Reinforcement methods include wire spiral and braiding. However, wire spiral hoses tend to expand in high pressure and have a low bend radius, reducing their capacity and response time. Fortunately, the new spiral hose technologies have overcome the inflexibility problem.
Durable
If you’re in the market for durable hydraulic hoses, you’ll be happy to know that they’re widely available. Unfortunately, this is not the case for every type of hose. Thankfully, you can find an excellent supplier of hydraulic hoses in your local area. Whether you need a high-pressure hose or a flexible hose with a large diameter, your hydraulic hose supplier has a solution to meet your needs.
The quality of a hydraulic hose is directly related to the materials it’s made from. Durable hoses are formulated with high-quality rubber and are designed to withstand temperatures from 90°C to 150°C. If they’re constantly exposed to high-temperature environments, however, they can experience deterioration and loss of flexibility. To maintain the durability of the hose, it’s important to use the right kind of hydraulic oil. The viscosity of the oil should match the specifications provided by the manufacturer.
It’s also important to know which fluids a hydraulic hose is compatible with. If it’s not compatible with the hydraulic fluid, it can damage the hose tube and cause a malfunction. Using an oil that’s not compatible with the hydraulic fluid can damage the hose. To be safe, you should check the compatibility chart to make sure your hydraulic hose is compatible with the fluid in your hydraulic system. Usually, hydraulic hoses are compatible with petroleum-based oils, but new biodegradable fluids can pose problems. You also should verify the working pressure of the hose, which should be equal to or higher than the maximum pressure of your system. You should also make sure that the pressure doesn’t spike higher than the published working pressure because this can greatly shorten hose lifespan.
Resistant to abrasion
As a performance characteristic, abrasion resistance is a critical consideration in the hydraulic hose industry. Abrasion resistance is measured using the International Standardization Organization (ISO) 6945 Abrasion Standard. In this paper, we evaluate the effectiveness of this standard by examining abrasion resistance in a series of hose cover tests. The methods used to evaluate abrasion resistance are the test to failure and weight loss.
The abrasion resistance of a hose can be achieved by using a protective sleeve. This covers the hose and provides pinpointed abrasion protection. Hose shields are flexible and easy to install. They are available in lengths of 4, 6 and 8 inches, and can protect hoses with an I.D. ranging from 1/4 to 2 inches. However, hose shields should not be used in applications that cause excessive abrasion or vibration.
Hose protection shields are a low-cost solution. Cable ties are used to join these sleeve sections to the hose. These sleeve covers can be removed without damaging the hose. Moreover, they should not be used on large sections of hose. However, for heavy-duty applications, abrasion-resistant hose covers from manufacturers like Parker are a superior solution. The ToughCover series and the SuperTough range of hose protection shields offer four times more resistance than normal abrasion-resistant sleeve sleeves.
Easy to route
The best way to avoid a kink in your hydraulic hose is to route it in a straight line. This will help prevent abrasion on the hose and prevent it from breaking down prematurely. You can find the bend radius for your hose on a SAE spec sheet or in a manufacturer’s catalog. It’s also good to avoid bending the hose too much, as excessive bending can lead to future problems and premature failure. You should also look for a swivel end for easier routing.
If you must bend your hoses, remember that they will not be as flexible as you’d like. You’ll have to take special care when routing them because a sharp bend can cause them to stretch. Excessive flexing can also cause the hose to burst. You can prevent abrasion by carefully routing your hose and using clamps. If you do bend your hoses, ensure that they are not rubbing against each other.
You can use a swivel or rotary joint to prevent bending of the hose when fitting. Regardless of which method you choose, make sure to leave extra length for adjusting when you need to pressurize your hydraulic hose. Also, remember that hydraulic hoses should not be dragged, as this can cause the pressure to increase, stressing the fitting connection. It also can cause sealing failure if your hoses are too tight.

Easy to install
If you are looking for an easy to install hydraulic hose, you should start by understanding how they are designed. In general, hydraulic hoses have continuous lines of information on the outside, known as lay lines. If these lines are spiraling, it means the hose was twisted while installing. A twisted hose may fail prematurely. To fix this problem, loosen the fittings and untwist the hose.
A hose should be cut long enough for the minimum bend radius. It should be cut slightly longer than the required length to account for expansion. Under pressure, a 24″ hose can increase in length by 2% to 4%. If you’re working with a compressed hydraulic hose, you need to ensure that you have enough length to route it properly. If you’re using too short a hose, you risk damaging your system.
To install a hydraulic hose, start by threading it into the corresponding port. Always ensure that you have a good seal and do not overtighten it. It may sound confusing, but you will be glad you did it once you know how. In addition to that, the hoses are easy to install – even if you’re not an expert. After all, you want the hose to work properly.
Chemical compatibility chart
Listed below are some guidelines for choosing a hydraulic hose. These charts are provided as a guideline for compatibility, but it is advisable to test hoses before installing them permanently in your system. The compatibility chart assumes that the fluid and temperature are 70 degrees Fahrenheit. Heat can cause undesirable chemical reactions, causing components to fail. As a result, it is important to use hydraulic hoses with the proper protection against heat.
Choosing the correct hose depends on the type of pressure, fluid temperature, ambient temperature, and other special requirements. Always follow legal regulations, as well. Fluid manufacturers can also provide recommendations if the compatibility chart does not show the correct fluid. In addition, the Technical Service Department of Motion & Flow Control Products in Wickliffe, Ohio, can help you identify suitable hydraulic hoses for your application.
