Zeagle Atomic Aquatics B2 Regulator 1st Stage - REG192 DIN, SEAL
Atomic Aquatics understood that not every diver could afford Titanium. Even though every Atomic regulator has all metal second stage components made of Titanium, we designed an affordable first stage using brass; the B2. The Atomic difference is the performance, reliable design, and the durable chrome-plating process we developed.
The Jet Seat Piston. 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.
Features
- Large, balanced flow-through piston design for stable intermediate pressures and high performance at low tank pressures
- Environmentally seal option available (highly recommended) for freeze protection at colder temperatures and all around protection from sediment entering the first stage
- Availble in Yoke or DIN options
- Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance
- Service to 4350 psi (300 Bar) with optional DIN connection
- Nitrox EAN ready to 40% O2 (M1: up to 80%) from the factory with no internal modifications needed
- CNC machined from solid bar material, the body maintains perfect alignment of the piston and seat to eliminate creeping intermediate pressure problems
- Two high-pressure and five low-pressure ports on swivel cap (T3/B2/ST1/M1)
- Two high-pressure and option of five low-pressure ports on swivel cap or seven low-pressure ports on fixed cap (Z2/Z2x)
- All Atomic first and second stages are Made in USA with Limited Lifetime Warranty, and 2 year/300 dive service interval
