All About Gas Struts: How They Work & Why You Need Them
What are gas struts?
Gas struts, also known as gas springs, are a type of spring that uses compressed gas (usually nitrogen) to create force. The force created by the gas strut can be used to assist in opening or closing a door, hatch, or lid. Gas struts are often used in automotive applications, such as hoods and trunks, but can also be found in furniture, RVs, boats, and more.
When purchasing a gas strut, you will need to know the weight of the object it will be supporting and the length of travel required (how far the object needs to be opened or closed). With this information, you can then select a gas strut with the appropriate force rating.
It is important to note that the weight of the object being supported is only part of the equation—the speed at which the object is moving also needs to be considered. If an object is being moved quickly, a gas strut with a higher force rating will be required.
How do gas struts work?
As mentioned above, gas struts use compressed gas (usually nitrogen) to create force. The pressure of the gas inside the strut is what gives it its strength. When the strut is not in use, the pressure inside the strut keeps it closed. However, when you need to open or close a door, hatch, or lid, the pressure can be released, allowing the strut to assist in opening or closing the object.
Why do you need gas struts?
Gas struts are a great way to make opening and closing heavy doors, hatches, and lids easy. They can also be used to keep these objects open or closed. For example, many people use gas struts to keep RV doors from slamming shut in windy conditions. If you have ever tried to open a heavy door or hatch without a gas strut, you know how difficult it can be—and how dangerous it can be if the door or hatch slams shut unexpectedly. Gas struts can also be used in furniture, such as recliners and Murphy beds, to assist in opening and closing.
Where are gas struts used?
A gas strut has a variety of uses. Its not too hard to find one that would suit your needs. Some common applications for a gas strut are:
- Automotive hoods and trunks
- RV doors and windows
- Furniture, such as recliners and Murphy beds
- Boat hatches and doors
- Machine shop doors
As you can see, gas struts have a wide range of uses which also includes some industrial applications. If you have a need for a gas strut, be sure to select one that is rated for the weight of the object it will be supporting and the length of travel required. With a little bit of planning, you can make opening and closing heavy doors, hatches, and lids easy—and keep them from slamming shut unexpectedly.
When do you need heavy duty gas struts?
Heavy duty gas struts are typically needed when the object being supported is very heavy or if the strut will be subjected to a lot of wear and tear. For example, automotive hoods and trunks are often opened and closed multiple times a day and can be very heavy, so they require heavy duty gas struts. Similarly, RV doors and windows are often opened and closed multiple times a day and can be very heavy, so they also require heavy duty gas struts. If you are unsure whether you need a heavy duty gas strut, consult with a professional to determine the best option for your application.
When do gas struts need replacing?
Gas struts typically need to be replaced every 3-5 years, depending on how often they are used. If you notice that your gas struts are losing their strength or are not working as well as they used to, it is probably time to replace them. Similarly, if you notice any damage to the gas strut, such as a leak, it is also time to replace it.
