Your Guide To Finding The Right Hydraulic Fittings 

Hydraulic hose fittings are typically used to link hydraulic hoses, pipes, and types to cylinders, valves, pumps, and all the other components that belong to the hydraulic system. So what will happen if the hydraulic fittings that you chose are different from what you need? 

Unfortunately, even the smallest deviance in the fitting can rapidly decrease the entire hydraulic system’s effectiveness. It may even cause a major concern for safety. If you find yourself overwhelmed with all the options in hydraulic fittings that you must consider, here is a guide that could help you pick the best fit for your project. 

What Is a Hydraulic Hose Assembly?

Like most people, especially if you are not working in an industrial field, the first time that you need to decide the kind of hydraulic fittings to use is when you are about to do a hose assembly. Nowadays, crimping is the most common assembly method for hydraulic hose. 

Before beginning any hose assembly, it would be ideal to ask yourself about the STAMP, or the Size, Temperature, Application, Materials/Media, and Pressure. After identifying these specifications, you can ask a hose assembly technician to start the assembly process. 

Hydraulic Hoses, Pipes, And Tubes: Everything You Need To Know

It is crucial to determine the type of hydraulic equipment that must be connected in the system to know which hydraulic fittings must be used.  

  • Hydraulic Hose – It is graded by temperature, hydraulic pressure, and fluid compatibility. These hoses are utilized in any projects where the other equipment is not suitable. It is also chosen by the hose assembly technician to offer flexibility during machine maintenance or operation. Also, the hydraulic hoses usually come with steel fittings placed on its ends. 

  • Hydraulic Pipes – This type of equipment is usually intended for low-pressure applications. They can either be linked by threaded connections or welds. Due to its large diameters, the hydraulic pipes are often internally inspected after the welding. 


  • Hydraulic Tubes – It is smaller than the pipes. The tube lengths are often interconnected using flanges, flare connections, cut-rings, or welding nipples. However, always ensure that the direct connection of tubes using welding method is not permissible since you cannot inspect the interior if you do it. 

Things To Consider When Choosing Hydraulic Fittings

If you need to select your hydraulic fittings, you need to ensure that you will only use the National Pipe Taper (NPT) pipe thread fittings all the time. If you do not do this, you may increase the chances of getting a crack in the fitting. 

You must also look into the pressure rating of your equipment to avoid over-torquing. You can choose the O-ring seals for this purpose. 

Other crucial factors to consider, include the temperature for tube fittings, the vibration, and the chemical compatibility and operating fluid of each component. 

If you still find yourself having trouble deciding which hydraulic fitting to choose, you could ask a hydraulic system expert to help you make a smart decision for your project.
