About Atomic T3

The T3 forges a new titanium standard as the absolute finest regulator you can own, regardless of price. The T3 is Atomic Aquatics signature regulator, providing you unprecedented reliability and performance. Amazing light-weight and dependable materials makes it the perfect choice for travel. You'll dive confidently in exotic locations, where service is hard to find. Atomic Aquatics was the first to design and manufacture an all titanium diving regulator. This exotic metal was chosen for its absolute corrosion resistance in ocean water, its strength, and its amazing light weight.

The T3 first stage has the features you have come accustomed to in an Atomic Aquatics regulator design. The T3 is a balanced flow-thru piston design using Atomics jet seat high flow monel piston. Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance. The Atomic jet seat system has no sharp edges that can damage the seat over time, like most competitors' first stages. Instead, Atomic employs a conical seat and blunt end piston. Atomics' 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 3-years or 300 dives without service. Diving performance is superior at even low tank pressure.

The T3 is also freeze protected with a factory sealed first stage that also prevents contamination such as silt and sand entering the mechanism. The regulator is Nitrox ready for mixtures up to 40% out-of-the-box. The first-stage has 2 high-pressure (HP) 7/16" and 5 low-pressure (LP) 3/8" ports. The LP ports are on a swivel turret for ease of hose routing.

The T3 second-stage is a balanced linear flow design for extremely easy breathing at all depths and dive conditions. Like the first-stage the T3 second-stage is built-to-last with a titanium demand valve body, lever and sealing orifice. The diaphragm is made from high quality silicone rubber. This pneumatically-balanced poppet second-stage has Atomics patented seat saving dynamic orifice which unlike most second-stage orifices is a floating valve design which reduces wear on the second-stage poppet seat when the regulator is not pressurized adding life to this important seal.

The T3 second-stage regulator is equipped with Atomics patented automatic flow control (AFC). This unique diaphragm activated vain automatically controls the flow and venturi-effect of the second-stage for optimum breathing resistance at all depths. The second-stage does have a soft over molded rapid adjustment knob for rare special situations. If you have ever experience the pulling effect" of the regulator second-stage when you turn your head underwater, those days are gone with Atomics all titanium comfort swivel with a black PVD coating. Perhaps one of the most admired features of Atomic second stages is the patented comfort swivel which allows 30° rotational movement without binding or kinking.

The T3 has a new high-flow second stage case and magnum lever design that significantly lowers breathing effort at any depth from shallow water to beyond the limits. A dual material second stage cover enables entire front to be used for purging and a dual silicone comfort fit mouthpiece with tear resistant bite tabs. The T3 has a metal accented front cover ring. The regulator comes equipped with a 3/8" threaded 32" (81.3 cm) low pressure hose, weighs 1.6 lbs. (734 g) and comes with an owner's manual and travel bag.

The regulator and instruments are the heart of your life support system for diving. Want maximum protection for your regulator set-up, maybe with long hose, dive computer, and other instruments? Don't skimp on protection, use the Atomic Padded Regulator Bag. Keep your regulators and expensive equipment separate from the rest of the gear. This bag is large enough to hold regulator, gauges, and an octopus. Fully padded bag measures 16.5" x 11.5" x 5" (42 cm x 29 cm x 13 cm) with a volume of 1,129 cubic inches (18.5 liters) and is made of rugged 1050 Denier nylon. Bag features a reinforced, contoured rubber grip covered carry handle for comfort while carrying and comes equipped with a detachable, padded shoulder strap for ease of transport.

The Atomic Padded Regulator Bag boasts a padded internal compartment. The main compartment also features three more storage areas: a large, hook and loop closure pocket, a smaller mesh zippered pocket, and fully lined zippered pocket. There is an external zippered compartment for items you need close at hand. Regulator bag is black in color.

Questions & Answers

Questions about this item:

John M  just bought a T3 regulator from you. When attaching to a tank, it appears that is attached horizontally with 2nd stage over right shoulder. Is this correct? If correct it appears that I will need a longer BC lp inflator hose, I have a 22" standard. What length would you recommend? Also, what about drysuit lp hose, will this have to be longer hose? I have a 3 console genesis gauge, bought from you, will the length be long enough? Thank you
Donald K  John, I have the T3 also from Leisure Pro. I have my second stage coming over my right shoulder. My octopus coming under my right arm. A backup HP analog SPG also coming under my right arm and clipping onto a d-ring. Dimensions are primary 2nd stage is 31" to swivel, octopus is 34 1/2"to the swivel, and the HP backup SPG hose is 30 1/2". Over my left shoulder is my LP BCD hose which is 27". Under my left arm is my HP computer hose of about 34" and currently my LP dry suit hose of 33". I can send a few picks if you send my an address.
John M  "Thanks, Donald. Pictures would be great.Thanks, again.
Donald K  I can't figure out how to post a pic in this response. Send me an email address or phone # or email me at Donald.kingiii at yahoo and I'll send you a pic. I just put my reg on a tank to answer your question and took a pic with the intention of posting with my original response.
KEVIN F  Please contact our technical department at 800.637.6880
Shopper  What screws into the HP ports & which items come off the LP Ports? Thks
Frank L  HP ports are for your pressure gauge and/or transmitters for Computers. Everything else (second stages, inflator hoses) go into the Low pressure ports.
Shopper  Can you get a yoke adapter for this regulator?
Frank L  We do not have a Titanium Yoke adapter, but you could get a standard brass one:
