How Do Gas Struts Work for Your Needs?

Gas Struts

Gas struts are fantastic and have countless applications. The ability to lower and lift in a controlled action, which increases safety and usability, is the main advantage of using these struts. Most frequently, these struts are used to help raise and lower hinged doors, and you can use them on your overhead cabinets or truck canopy. They are also utilized in a wide variety of other products, including office and transportation equipment.

For windows, hatches, and doors that need to open and close smoothly, gas strut is employed. They are particularly helpful because they are hydraulic, which means that they can only move with an external pressure. This ensures a smooth open – close motion. Find out how gas struts tend to work, and the mechanism of their function.

How Does Gas Strut Work? 

A gas spring functions as an energy storage mechanism in the same way as a mechanical coil spring. A gas spring, on the other hand, stores energy by compressing the nitrogen gas that is housed inside, as opposed to putting a strain on the material that the coil spring is made of.

A gas spring is distinct from a hydraulic or pneumatic cylinder, despite having a similar appearance, since it does not need an outside source of energy to move.

In gas springs, whether the piston is completely extended or fully closed, the pressure is constant on either side of the piston. Another distinction to be made is that a hydraulic or pneumatic cylinder cannot move unless a pressure differential exists across the piston.

So how does it function if no additional gas is added?

  • Because of the difference in the cross-sectional region of the rod, where the gas cannot exert any pressure, the struts operate through Gas Struts stretch.
  • The rod extends because of the pressure differential between nitrogen gas working on its interior face and the air pressure pushing on its exterior end.
  • The available volume is decreased, the gas is compressed, and the pressure within rises as the rod is forced into the tube.
  • This compression produces the spring-like behaviour. Gas can flow across piston and via an opening in the rod-attached piston, which also regulates the speed of extension.

How To Choose Gas Strut? 

Now that you are aware of what gas strut actually is and what kind of benefits it has, but how do you choose the proper one?

There are various uses of gas struts. Some are taller than others, and some can lift more weight than others. This means that choosing the ideal gas strut for a task, you need to pay attention to the weight capacity that needs to be moved.

Fixed Forced 

Several fixed force struts available for purchase can help you choose an exact replacement for your old ones and make the transfer easily. There are options for all kinds of purposes, ranging from tiny rods of 6mm to 14mm variants for more potent uses. Both custom-sized gas struts and the refilling of worn-out ones are available.

Stainless Steel 

For corrosive or sterile situations like those found in medical or maritime applications, stainless steel struts are perfect. They may be washed without running the risk of corroding, making them perfect for the food sector.


Struts with adjustable force are pre-set to the optimal force. At the strut’s end, a release valve is there that enables gas to be vented out, reducing its force. This enables fine-tuning even with the gas strut fitted.

Once you have made the decision to replace your out-dated gas strut, a few easy steps are there for you to take to find a new one. Finding out the rod diameter of your current gas strut and browsing through online catalogues (sorted by diameter) can let you discover the ideal strut for your task.


You do not have to stress about selecting the proper gas struts for your project, no matter what it is. If you know exactly what you are searching for, you can be sure that you can get it. If not, you can even order a supplier to get it construct the strut you require.
