Product Information
The Atomic Aquatics B2 Regulator package combines a T3-inspired second stage design with a chrome-plated brass first stage and all-titanium construction elements, delivering reliable performance for scuba diving. The pneumatically-balanced design promotes smooth breathing across depths and tank pressure, supporting underwater exploration as part of a complete scuba gear setup with the included Yoke and Color Kit plus Z2 Octo.
Built for durability and consistent breathing, this package emphasizes materials and design that are trusted by divers. The chrome-plated brass first stage with 316 stainless components and all-titanium construction, along with a high-flow Jet Seat piston, provides stable airflow at varying tank pressures. The system is Nitrox-ready for mixtures up to 40%, includes a factory-sealed option to guard against silt and sand, and offers accessible tuning with a soft overmolded Rapid Adjustment Knob and an Atomic AFC for stable performance underwater.
The Z2 Octopus complements the B2 regulator with precision-machined brass, zirconium plating, and titanium components, plus a Titanium Seat Saving Orifice and Atomic AFC. A high-flow second-stage case reduces breathing effort across a wide range of depths, and a rapid adjustment knob allows manual detuning as needed. Optional color kit allows personalization of the diving gear while maintaining underwater performance.

Frequently Asked Questions
How often does a scuba regulator need servicing?
Follow the interval in your regulator's manual, since manufacturers commonly specify an annual inspection or a set number of dives and many warranties depend on it. A regulator is life-support equipment, so service belongs with a factory-trained technician rather than being attempted at home. Have it looked at sooner than scheduled if you notice increased breathing effort, free-flow, bubbles, or water in the second stage.
How do I rinse and care for a regulator after diving?
Make sure the dust cap is dry and firmly seated over the first-stage inlet before the regulator goes anywhere near water, because water inside the first stage is the leading cause of internal corrosion. Rinse in fresh water without pressing the purge button, since purging while depressurized can draw water back into the second stage. Shake out the water and hang it to dry with the hoses in wide, gentle loops rather than tight bends.
Can I fly with a scuba regulator?
Regulators travel well and are usually best carried in hand luggage where they will not be crushed or lost. A regulator holds no gas of its own, so there is nothing inherently problematic about it on an aircraft, though the airline and security screeners always have the final say. Pack it dry with the dust cap in place, in a padded regulator bag or wrapped in soft gear.
Can I use my regulator with nitrox?
Many modern regulators are supplied as suitable for nitrox mixes up to 40 percent oxygen, which is the widely used recreational industry standard, while anything above that requires dedicated oxygen-clean equipment and procedures. Confirm what your specific regulator's manual states, and follow your nitrox training and your fill station's requirements. Never assume a regulator is oxygen-service clean simply because it looks clean or is new.
What is the difference between DIN and yoke regulators?
A yoke (A-clamp) fitting clamps over the tank valve and is the most common connection across much of the recreational world, while a DIN fitting screws into the valve and is standard in much of Europe and in technical diving. DIN captures the o-ring inside the threads, which many divers consider more secure, but yoke is often what rental cylinders provide. Adapters exist in both directions, so check what is used where you dive before deciding.
What is the octopus regulator for?
The octopus is your backup second stage, carried so you can share air with a buddy who is out of gas, or breathe from it yourself if your primary fails or free-flows. It is normally on a longer, brightly colored hose so it is easy to find and hand over under stress. Secure it in the triangle between your chin and the bottom of your rib cage so it is instantly accessible and not dragging through sand or coral.
How should I store a regulator between dive trips?
Store it fully dry, out of sunlight, with the dust cap in place and the hoses in wide loops rather than tightly coiled. Avoid hanging it by the second stages for long periods, which stresses the hose fittings; laying it flat in a padded bag or hanging it by the first stage is kinder. If it has sat unused for a long stretch, have it checked before your next trip rather than assuming it is ready to dive.
