Gas springs have a number of advantages over coil springs.

1.   Typically gas springs have a low compression rate, but if required this can be increased.

2.   With a wider range of end fittings available, gas springs can be easier to fit.

3.   They can offer a much higher force in a smaller package than coil springs.

4.   A wide range of additional features can also be offered.

5.   On compression they do not bounce back, and the extension rate can be controlled, giving a smooth return.

The many useful variations include:

1.  A gas spring can have a locking shroud to fix it in the extended position.

2.  They can be made in 316 stainless steel for applications in the marine, medical, food and other industries.

3.  Tension as well as compression springs are available.

4.  They can be made in aluminum where low weight is of great importance.

5.  Gas springs should be used rod downwards.  Where this is not possible an oil chamber can be provided so that the spring can be mounted in any position.

6.  Locking gas springs can be locked in any position throughout the stroke.  This is particularly useful for reclining chair backs, foot rests, medical chairs etc.

7.  A release valve can be included so that the user can adjust the spring force as required.

8.  Fully damped springs contain separator pistons.  This separates the oil from the gas inside the spring so that the damping can be very closely controlled in either compression or extension.
