A2Z Seals is one of the leading suppliers of gas seals, which are assured of their highest quality. The design of these seals is derived from pusher seals that are known to have outstandingly fine laser-machined grooves on the outer side of the rotating seal face. Herein, the most common groove is a spiral profile. The dry gas seals are installed in new rotary compressors. With the passage of time, the applications of A2Z gas seals are widening into turbines.
