The design of this gastight piston ring is aimed at providing maximum efficiency in conditions that involve, for example, flushing or steering ports needing to be bypassed. The geometry is aimed at ensuring dual action and thus sealing optimally in both axial directions.

Dual gastight cut / Type I

There are several versions of this type of lock, but all have the same dual sealing effect. Given the geometry of this lock, a precise production process is extremely important to achieve a properly functioning end product.

This type of lock can be used in:
– Hydraulic systems
– Safety & control valves
– Gas turbines
– Shock absorbers
– Compressors
