What Are The Most Common Types Of Hydraulic Hose Fittings?

HomeTechnologyWhat Are The Most Common Types Of Hydraulic Hose Fittings?

Hydraulic hose fittings are an important component for running hydraulic machinery. You’ll find the use of these fittings in plenty of industries. Each type of hose fitting has a specific use and different specifications.

There are a lot of things that you’ll need to consider when choosing from different kinds of hydraulic hose fittings. For instance, you’ll have to check the requirements of your hydraulic machine, the size of the hose needed, and many other things.

Here, we’ll talk about some of the most common types of hydraulic hose fittings so that you can choose one that’s perfect for the job. But first, let’s learn a little more about this component.

 A] What Are Hydraulic Hose Fittings?

Hydraulic hose fittings are an important and common component of hydraulic machines or any hydraulic system. With these fittings, you can connect hydraulic hoses to any machinery or system that needs hydraulic fluid to run.

In simple terms, hose fittings serve the purpose of connectors. You can link them to pumps, cylinders, valves, etc. so that your machinery keeps running without any interruption.

B] Why Does Choosing The Right Hose Fitting Matter?

Picking the wrong hose fitting can lead your production process into serious trouble. A wrong fitting can affect your machinery’s efficiency.

Sometimes, you might also witness leaks that might cause a loss of hydraulic fluid. By using the wrong hose, you’ll also end up compromising the safety of operations.

So, which type of hydraulic hose fitting should you choose? Let’s take a look at the most common hose fittings to answer this question.

C] Common Hydraulic Hose Fittings

Here are the top hydraulic hose fittings that you’ll find in the market.

1. Double Ring Fittings

Double ring fittings are compression fittings that you can use for machinery that requires medium to heavy pressure. These hose fittings are also known as Swagelok fittings.

Double-ring fittings help you in creating a strong and leak-tight connection. What’s great about these fittings is that you can install them without any hassle. All you’ll need is a wrench to secure the connection.

These fittings are an ideal match for most pipe and hose sizes. You can use them for copper, stainless steel, and plastic tubing.

2. ASME Fittings

Just like double ring fittings, ASME fittings are high-pressure fittings. They find use in industries where there should be a tight and secure connection. ASME fittings allow you to resist high pressure and ensure the optimum functioning of the machinery.

3. Single Ring Hydraulic Fittings

Hydraulic hose fittings with a single ring help you join pipes and tubing in hydraulic systems. These fittings are available in different shapes and sizes.

Sing ring fittings are capable of bearing pressure of up to 800 bars. You’ll find these fittings in two standard materials: 316 stainless steel and carbon steel. Single-ring fittings are highly reliable. You can use it for high-pressure industrial applications without a second thought.

4. Hydraulic Quick And Automated Fittings

Quick and automatic fittings usually come in two types. These include push-in and push-on fittings.

Push-in fittings have an outer metal nut and an inner nipple. You can connect it by inserting the tube in the nipple and securing it by tightening the outer nut.

Push-on fittings comprise an outer ring made of red or blue plastic. This plastic holds the tube securely without the need for tightening any nuts. They are known as “Festo” type fittings.

Both these fittings are made of brass or stainless steel and are available in various shapes, forms, and thread options.

5. High-Pressure Hydraulic Hose Fittings

Industries that require very intense high pressure in the production process often use high-pressure hydraulic hose fittings. These fittings can handle pressure ranging from 400 bars to 4140 bars.

These fittings include are available in two types:

  • Cone & thread MP or medium pressure fittings that can handle pressure up to 1380 bars. 
  • Cone & thread HP or connections that are designed for pressures up to 4140 bar.

You’ll find high-pressure hose fittings in a variety of shapes and sizes. The most common application of these hoses is in hydro generators or high-pressure hydrogen pipelines. These fittings ensure a watertight and high-pressure connection.

D] How To Choose The Right Hose Fittings?

Before you place an order for a hose fitting, make sure that you consider the below-mentioned factors.

  • Check your hydraulic machinery thoroughly and determine what kind of hose will work best for it.
  • Every machinery in the industry might operate under different temperatures and pressures. Make sure you examine these two things. If your machinery’s industrial application requires high pressures, you must choose the high-pressure fittings.
  • Don’t forget to consider if the material of the hose fitting is compatible with your machinery. Choose a fitting whose material is compatible with the fluid being transferred.
  • Consider the environmental conditions in which you are operating the machinery. For example, if your machinery runs outdoors, you should pick a hose fitting that is resistant to any environmental effects.
  • Finally, you must also take note of the specific application of your hydraulic system. Some systems might need quick-connecting fittings. Whereas, you might need threaded fittings for other hydraulic systems.

Wrapping It Up!

Hydraulic hose fittings are the most important components of the hydraulic systems. They allow your machinery to work efficiently by letting the fluid flow without any disturbance. But you’ll be able to enjoy the benefits of hydraulic hose fittings only when you choose the right type.

These hose fittings are some of the most common hydraulic hose fittings you’ll find in the market. But it doesn’t mean that you can choose any random hose fitting for your hydraulic system. Make sure you carefully consider every aspect of your hydraulic system to avoid landing with the wrong fitting.

Choosing the wrong hose fitting can defeat the whole purpose of this important component. It might even affect your hydraulic system negatively. So, know the difference among different hose fittings and choose the one that’s best suited for your industrial application.
