Getting the Right Fit: How to Source Proper Fittings for Hydraulic System Assembly

Date: 31-01-2020

From automotive to agricultural industries, many companies rely on hydraulic systems to complete the job. Every component of the system must work properly, including hoses and fittings. But the problem is that fittings are often overlooked when looking for hydraulic equipment for sale and during assembly, causing hose failures when the system is in use.

Where the Problem Lies

It seems fitting to recognise how poor fittings cause hydraulic hose failure. Here are a few examples:

  • Fitting blown off the hose

The possible cause is that the hose wasn’t inserted deeply enough into the shell of the fitting. Hoses and fittings aren’t universal — using fittings that seem to fit the hose won’t cut it. Ensure a witness mark is used so that you know the fitting is pushed on far enough. You should always choose fittings that are compatible with the hose you want to use for the hydraulic system you’re assembling.

  • Leakage between the fitting and hose

If there’s leakage between the hose and the fitting, the culprit is likely improper crimping. Purchase crimp fittings suitable for your hose size or use a reliable tool to crimp fittings to the proper diameter. Always make sure you know what the correct crimp specification is, as specified by the manufacturer.

  • Hose burst at the fitting

There are many possible reasons behind a hose bursting at the fitting. It could be the hose length is too short, or it excessively moves within the fitting because their sizes don’t match. It could also be the case that the hose bend is too close to the fitting or again, the crimping dimension isn’t accurate. For some of these, the first step in solving the problem is getting the right fitting size and type before assembly.  

Solve the Fitting Problem at the Root

You may have a hose that can handle high amounts of hydraulic pressure, but without the right fittings, it is useless. Keep in mind that the weakest area on many hydraulic systems is the connection points. Fortunately, you can address the problem at the root — at the supply level. Here are some of the most crucial factors to consider when buying fittings for your assemblies:

  • If the size of the hose and hydraulic fitting aren’t compatible, it can cause fluid leaks and system failures. It isn’t enough the hose seems to fit into the shell of the fitting — it must fit snugly.
  • Fittings are specific to various temperature ranges. Be sure to place an order for fittings that can withstand the internal and external environment of the application.
  • The design and manufacturing of various types of fittings usually depend on the pressure ratings of the application. Again, make sure that those two variables match.
  • Material features. Keep in mind that hydraulic fittings come in a range of shapes and material features to provide specific functions required in different industrial applications.

Hydraulic hoses must always come with precise fittings for the system’s optimum performance and safety. Compatibility, however, may be difficult to achieve, especially if you don’t have a reliable parts supplier. This is where Armadillo Group comes in.
