Gas struts are essential devices that can be used in various applications, providing controlled movement and support for opening objects like hatches and doors. Over time, gas struts can experience a loss of gas, affecting their functionality. In this article, we will cover how to recharge gas struts. You will learn the safe way to go about it.
How gas struts work
Gas struts work on the principle of gas compression. When the strut is compressed or extended, the piston moves within the cylinder, compressing or releasing the gas. This compression creates a force that opposes the motion, providing resistance and controlling the movement of the object. In essence, gas struts lessen the force needed to open the attached object. They also provide a dampening effect on closing, ensuring the safety of the user.
What are the signs that your gas spring is no longer functioning properly?
It is important to identify signs of gas strut failure to ensure the optimal functioning of the supported mechanism. Here are a few common indicators:
- Difficult to open or close: if you notice uneven or challenging opening and closing of doors, hatches, or other objects, it may be a sign of gas strut failure. The struts may no longer provide the necessary support and resistance, causing imbalanced movements.
- Loss of pressure: a sudden loss of pressure in a gas strut can result in a weak or ineffective support of the attached object. This can lead to difficulty in keeping doors or lids open, posing potential safety risks.
- Squeaking or hissing noises: strange noises, such as squeaking or hissing, during the operation of gas struts can indicate leaks or damaged seals. These issues can affect the performance and lifespan of the struts dramatically. We advise you to replace the gas strut if this is an issue.
Recharging gas struts
Recharging gas struts is a potential solution to restore their functionality. Please note that regassing gas struts requires special equipment and training. We advise you not to try and recharge the gas strut yourself but instead seek professional assistance to regas your gas struts safely.
When do you need to replace your gas strut?
Gas struts typically have a life span of 8-10 years. If your gas struts are approaching this age, it is recommended to purchase new ones. This is because of deterioration of the seals which keep the gas within the cylinder. If the gas struts show visible damage or extensive leakage, it is advisable to replace them. Purchasing new gas struts ensures optimal performance and reliability. In addition to being able to replace the gas spring, it is also possible to calculate the dimensions based on the application. Or to order a new one based on the gas spring dimensions, please select them in our configurator.

- Can I regas my gas struts by myself?
Regassing gas struts requires specialized equipment and training. We advise you to seek professional assistance to regas your gas struts safely. - How long do gas struts typically last?
Gas struts have a lifespan of 8-10 years. If your gas struts are approaching this age, it is advisable to consider purchasing new ones instead of regassing them. - Are all gas struts suitable for regassing?
Not all gas struts can be regassed. The condition of the struts, especially the seal, and their age should be considered before opting for regassing. - What should I do if my gas struts show visible damage or leakage?
If your gas struts exhibit visible damage or excessive leakage, it is recommended to replace them rather than relying on regassing. Purchasing new gas struts ensures optimal performance and reliability.
