What Happens When You Choose the Wrong Hydraulic Fitting?

Selecting the wrong hydraulic fitting may seem like a minor issue but can have far-reaching consequences for your business.

One of the most common impacts operators of hydraulic systems observe is the presence of one or more leaks. When a seal fits incorrectly or the hydraulic fitting is not designed for the type of work you have it doing, linkages can fail.

At the very least, a leak will reduce the effectiveness of your system. At worst, it can lead to the mixing of incompatible substances, which could lead to explosions or the creation of toxic byproducts.

Additionally, when working with high pressure, incorrect usage can increase the risk of hydraulic fluids being injected under the skin of operators. Pressure could also result in flying projectiles that lead to serious injury or damage to property.

Exploring Different Types of Hydraulic Hose Fittings

Hydraulic hose adaptor fittings come with a variety of specifications, based on the job they are designed to do.

Various industry standards, such as the applicable ISO for your industry, may also dictate the type of fitting you need. It is not recommended that you mix fittings from different manufacturers.  

The main types of hydraulic hose fittings are:

–          Permanent crimp fittings – These fittings result in a permanent attachment. Using a bench-based or portable crimping machine, this fitting creates a strong, reliable connection. This type of fitting is essential for high-pressure systems.

–          Field-attachable hydraulic hose connector fittings – Easy to apply out in the field, this fitting type is a convenient solution when an immediate repair is needed. It can also be reused elsewhere. However, this fitting type is prone to failure and is not suitable for high-pressure systems. 

Factors to Consider: Threading, Sealing, and Compatibility

When choosing the right hydraulic hose pipe fittings for your requirements, it is also important to consider the following:

Threading – Ensure thread compatibility by always buying from the same manufacturer.

Sealing – Match the seal to the job. If using elastomeric seals, monitor your operating temperature carefully, because even one instance of over-temperature can cause seal failure.

Compatibility – Beyond simply making sure your fittings are compatible, it is important to ensure chemical compatibility, particularly for gaseous applications.

Choosing the right hydraulic hose is a crucial decision for many companies that rely on hydraulic systems for their day-to-day operations. It’s important to know that choosing the wrong hydraulic hose can dramatically affect equipment efficiency, safety and longevity by increasing the risk of failures that can lead to downtime and costly repairs. In this guide, I provide you with an overview of what to consider when going through the hydraulic hose selection process, so you can make an informed decision when it comes to choosing the right hose for your application.

Understanding Your Application

Before selecting a hose, it’s crucial to thoroughly understand its intended application. This involves knowing the fluid or substance it will carry, the environment in which it will operate, and the specific requirements of the system it will integrate with. Understanding these factors ensures that the chosen hose meets the performance, safety, and regulatory standards needed for its application.

Using The STAMPED Method

Effective hydraulic hose selection begins with a detailed understanding of your application’s demands. The STAMPED method guides this assessment, focusing on:

• SYSTEM requirements, including pressure, flow rate, and temperature considerations: It’s essential to evaluate the system’s operational pressure, the fluid’s flow rate, and the range of temperatures the hose will be exposed to during use to ensure compatibility and safety.
• TEMPERATURE range, both internal and external: The temperature range a hydraulic hose faces is key to selecting the right material and design. Hoses must handle the application’s maximum and minimum temperatures without degrading. High temperatures can hasten rubber aging and weaken reinforcement, while low temperatures may cause brittleness. Temperature extremes also affect fluid viscosity and system efficiency.
• APPLICATION specifics influencing hydraulic hose selection: The specific application of the hose — whether it’s for heavy machinery or manufacturing and maintenance equipment — dictates the hose choice to ensure optimal performance and compliance with industry standards. Different applications may require hydraulic hoses with various characteristics, such as flexibility, abrasion resistance, or compatibility with specific fluids.
• MATERIAL compatibility with the conveyed fluids: Ensuring that the hose material is compatible with the fluids it will carry is vital to prevent chemical reactions that could lead to hose deterioration, leaks, or system failure.
• PRESSURE requirements, encompassing both working and burst pressure: The hose must be able to withstand the system’s maximum working pressure and have a burst pressure rating high enough to provide a safe margin for unexpected surges or spikes in pressure.
• END fittings needed for the hose: Selecting the correct end fittings (e.g., JIC, NPT, flanges) for the hose is essential for a leak-free connection and compatibility with the existing system components, ensuring easy installation and maintenance.
• DELIVERY of fluid and hose: Delivery ensures optimal fluid velocity and volume in hydraulic hoses for system efficiency. It also encompassed considerations such as managing hose logistics and availability to prevent downtime and delays.

Environmental Factors of the Application

In addition to STAMPED considerations, environmental factors external to the application like exposure to chemicals, abrasion, and UV radiation have an impact on hydraulic hose selection.

• Chemical exposure: The compatibility of hose materials with chemicals they might come into contact with is paramount for ensuring longevity, safety, and performance. For instance, hoses used in chemical processing plants must resist a wide range of corrosive substances.
• Abrasion Hydraulic hoses in dynamic applications, such as those connected to moving parts or used in abrasive environments (like construction sites or manufacturing floors), are susceptible to wear and tear from external abrasion. Materials engineered for high abrasion resistance can help withstand these conditions much better.
• UV Radiation: Continuous exposure to UV radiation can deteriorate many materials over time, leading to cracking, brittleness, and a loss of structural integrity. This is a critical consideration for hoses used in outdoor applications, from pressure washing to aerospace.

As you can see, choosing the right hydraulic hose for your application is very important. However, ongoing maintenance and inspection of your hose is also essential to ensure that it continues to operate safely and efficiently throughout its expected service life.

Matching the Proper Hydraulic Hose Using Specifications

Not all hoses are created equal. Once you’ve determined all the factors of your application, you’ll need to find the hydraulic hose that will meet the specifications of your system and its environment. That’s where hose specifications and advice from hydraulic hose professionals come in.

There are a total of nine key specifications to look for when selecting a hydraulic hose.

Another important factor in hydraulic hose selection is the type of hose. Years of research and development have identified the optimum hydraulic hose specifications for certain types of applications. Today, there are a multitude of hydraulic hose types grouped according to construction, material, and function to meet specific operational challenges. In order to simplify the selection of their hydraulic hoses, some manufacturers such as Gates have even developed a clever family classification system labeled on their product’s covers in addition to key technical specifications.

For example, braided hydraulic hoses are widely used in applications where flexibility and strength are essential, such as in construction equipment, mining machinery and industrial machinery. Thermoplastic hoses, on the other hand, are often used in medium and high-pressure hydraulic systems, for handling compressed air and gases, transporting chemicals, and for tasks such as water cleaning and paint spraying. There’s also a category of hoses known as fleet hydraulic hoses, specially designed for heavy vehicles and equipment, where they play a crucial role in braking systems, fuel distribution, facilitating the flow of grease and oil, and so on.

Knowing that these different hose categories exist, and understanding what characterizes them, goes a long way to helping you select the ideal hose for your application. Read our blog on the different types of hydraulic hoses to find out more.
