Description

Designed for scuba diving gear reliability, the Atomic Aquatics B2 Regulator, Yoke Sealed with Color Kit and Z2 Octopus pairs a chrome-plated brass first stage with the signature second-stage design from Atomic's T3. This setup delivers smooth breathing and consistent performance for diving in underwater environments. The package is Nitrox ready up to 40% and approved for non-dedicated EAN use, making it suitable for a broad range of diving scenarios.

The system includes an optional factory-sealed design to prevent outside contamination from silt and sand, protecting performance in underwater environments. It features a pneumatically-balanced poppet, high-flow case and lever design for easy breathing at all depths and tank pressures, plus a hose with a polished 316 stainless steel Atomic Comfort Swivel and Black PVD coating. The dual-material second-stage cover provides full purge access, while the elliptical exhaust valve reduces exhalation effort at depth. The Z2 Octopus offers high-flow second-stage components made of Brass with Zirconium plating and Titanium for reliability, along with a patented Atomic seat-saving orifice for consistent flow in the octopus.

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.
