Z2 First Stage – Unsealed

You know the moment you mount it on the tank
How can simply turning the tank valve and pressurizing the first stage of your new Atomic regulator be a life-changing experience? Atomic divers characterize it as “confidence.” They realize that a simple twist of the wrist energizes the finest piece of dive equipment made. They are confident that their Atomic regulator will perform perfectly – delivering the first easy, natural breath of their dive…every time they dive. That’s exactly what we expected when we crafted it for you.

Another Atomic Exclusive
Atomic designed the Jet Seat Piston to eliminate creeping intermediate pressures and minimize maintenance. This unique high-pressure piston seal system is leak-free and self-lubricating.

The Atomic Jet Seat system has no sharp edges that can damage the seat over time, like most competitor’s first stages. Instead, Atomic employs a conical seat and blunt-end piston. Our valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure.
