While gas springs and hydraulic dampers, specialized forms of springs that utilize gas under compression to exert force, are made in different sizes and lengths, selecting one is dependent upon two main factors, the mandatory spring force as well as the effective stroke with the spring. Application design considerations with the gas springs involves selecting springs with the proper sized cylinder and piston depending on the force needed for the application. For example, a corner lid of the car is based on two gas springs on either side with the lid, that if compressed produce a force that is roughly comparable to the load of the lid. Similarly with an chair, the force created by the gas lift ought to be somewhat higher compared to the weight from the chair, allowing the user to effortlessly slowly move the chair up and down. Furthermore, to stop buckling the buckling with the gas springs, the force produced should invariably be in keeping with its centerline, designed for a gas spring ball stud.


Another good point while selecting or designing a gas spring will be the ambient operating temperature, as both extreme cold and hot temperatures get a new operation. The alteration in temperature affects pressure that the gas spring can exert and therefore the output force. At high temperatures, the seal permeability increases and gas molecules may escape from the seal quicker. They are also designed based on the performance guidelines that include cold opening and closing efforts, hot closing and opening efforts, self-rise and self-close angle, hump, 70 degrees, and damping.

Resistance to dents, damage, and abrasion should also be ensured while designing the cylinder and the piston. Special features, for example external locking and variable damping, should also be considered. Safety factors are another major factor that is highly recommended while producing gas springs. As part of this factor, the suitability with the spring as well as the mounting position strength are considered. Additionally, a secondary locking mechanism may also be incorporated for safety purposes, if needed.

While mounting a gas spring, care needs to be taken to ensure that they're mounted in an upright fashion with the piston rod pointed downwards. This is to ensure that the rod seal is kept lubricated at all times. If the spring is usually to be mounted with an angle, care ought to be taken to ensure that the degree of the lubricating oil is enough for that rod seal to be always lubricated through the operation.
