About Atomic T3 Second Stage Only, 32" (81.3 cm) Hose, Gray

The T3 Second-Stage is a balanced linear flow design for extremely easy breathing at all depths and dive conditions. 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. 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. The Regulator weighs 12.63 oz. (358 g) with hose.

This product can only be shipped to U.S. addresses.

Questions & Answers

Questions about this item:

Shopper  Is there an Atomic long hose that will go with this regulator? If so how do I get it shipped outside of the U.S?
Mario C  Thank you for your question the longest hose i have for atomic is 7 feet. it only ships to US and Canada per manufacturer policy.
Anders N  I need a longer hose on my T3 and also preferably a 90 degree adaptor ( using it in sidemount setup ) what thread is on the regulator itself ?
Frank L  In order to change out the hose on a swivel 2nd Stage Atomic, you would need an additional part from Atomic. Please contact us directly for more information.
Shopper  If I purchase the Atomic T3 regulator (second stage only) and use it with my U.S. Divers Conshelf Sea first stage, will that let me use the new regulator to its full breathing potential? Or would air flow be restricted some due to not using a new atomic first stage?
Frank L  Not recommended, and the performance would suffer greatly.
Barton H  Will it function to its potential with a Scubapro or other Atomic Reg?
