The elastically lockable gas springs are then to be recommended if a spring-back of the lock is desired. Pulsed peak loads can be damped or even avoided this way.
These two models differ only in the diameter of the pressure pipe. Since the piston separates two gas chambers when the valve is closed, the piston rod also springs in the locked state due to exterior loads. Pulsed peak loads are damped or even avoided. This makes applications possible that require convenient locking.

The standard program for elastic locking gas springs includes two different types.
| Type | ∅ Tube(mm) | ∅ Piston rod(mm) | Stroke(mm) | Extension force* F1 (N) | Color tube | Color Piston rod | Type of locking |
|---|---|---|---|---|---|---|---|
| EL1 | 22 | 10 | 20 - 250 | 200 - 800 | black | Tenifer | elastic |
| EL2 | 28 | 10 | 20 - 250 | 200 - 1,000 | black | Tenifer | elastic |
* The extension force is selectable in steps of 50 Newton
