About Atomic Safe Second Inflator (SS1), Stainless Steel

When you took dive lessons you learned to perform specific skills to make you safe and comfortable underwater and at the surface. One of those skills was Buoyancy Control. Once you start diving for fun you use your Buoyancy Control Devise constantly throughout the dive. Your Octopus or Alternate Air Source Devise on the other hand is never used unless there is an Emergency Out of Air Situation. Reacting properly in an Out of Air Emergency can make the difference between a Safe Dive and a Tragedy. If your Alternate Air Source and your BCD Inflator Devise are one and the same you will always know where to find it in an emergency.

The SS1 is the newest and most sophisticated product of its type, taking the concept to new levels of Convenience, Reliability and Performance. It contains a High Flow Second Stage that performs on the same level as many High Performance Second Stages. It will deliver High Flow Rates to a Diver at Depth with a Minimum of Effort. It is, however very Stable and not prone to unnecessary Free-Flow or Leakage from Water Movement while Swimming, or during Entries or Exits. The Inflator/Deflator is Easy-to-Operate with Soft-Surfaced Buttons placed where they can be Easily-Operated with One-Hand.

One of the most unique features of the SS1 is its Adaptability to almost any BCD. Atomic has designed a Set-of-Adapters (patent pending) to fit virtually every poplar BCD brand available. The Adapters also include components for attaching the Cable Exhaust feature of your existing BCD (if applicable). The SS1 features a Quick Disconnect not only on the Low-Pressure Hose, but the BCD Hose as well. The Adapters that fit the SS1 to the BCD are connected to the SS1 with a Threaded Collar that can be easily Unscrewed-to-Detach it completely from the BCD. Now you can carry or store the SS1 with your Primary Regulator and Gauges (patent pending).

The SS1 combines the functions of the Inflator and Octopus Regulator into a Single Unit. This Reduces-the-Overall Bulk and Weight of your Dive Gear; Eliminates-Hoses, and places your Back-Up Regulator in a fixed, familiar location. This time proven concept is a Convenient-and-Efficient Alternative to the Dedicated-Octopus Second Stage. Reduce your Rig by One-Hose with the High-Performance Atomic SS1. The High-Flow, Low Pressure Disconnect is Interchangeable with many other Models yet smaller size and Lighter in Weight. Large Oversized and Ergonomically-Shaped Buttons are Easy-to-Find for Pneumatic or Oral Inflation/Deflation. They are Easy-to-Distinguish and Faced with Soft Tactile Rubber Surfaces.

The Elliptically-Shaped Body of the SS1 Lies-Flat against the BCD keeping it Out-of-the-Way and Reducing Drag. Seat Wear is the first cause of Regulator Leaks and Performance Degradation. The Stainless Steel Dynamic Orifice is Pressure Energized and Only-Contacts the Rubber Seat when in Use. Equipped with a Titanium Lever this High-Strength Metal part is the Link to your Air Supply and will Never-Fail due to Rust or Corrosion. The Integrated Purge Cover is a One-Piece Flexible Cover allows Purge of the Regulator when Depressed anywhere on the Cover Surface.

The SS1 has 316 Grade Stainless Steel Inflation/Deflation Stem, Quick Disconnect, Demand Valve Body, Orifice and Springs. The Mouthpiece and Diaphragm are Silicone Rubber and the SS1 Body is manufactured from Fiberglass Reinforced Nylon. The SS1 is a Dependable Downstream Demand Valve Design. The SS1 weighs 7 oz (200 g) without the Hose and the 3/8" Threaded Low Pressure Hose also weighs 7 oz. (200 g) and measures 28" (71 cm) in length. The SS1 comes with an Owner's Manual and is covered by a Limited Lifetime Warranty.

Lightweight, Excellent Breathing Second

The SS1 breaths nearly as well as my T1, which is saying something. Since I fly strictly carry-on, this fits very well with my "lighter is better" packing. Also it has a quick disconnect feature, allowing tooless removal from BC for easy packing. This is much lighter and breaths better than the very good Air2 it replaced.


Most Liked Negative Review


Good, but Noisy

All around good purchase. Easy to use, and very convenient, but extremely noisy to breathe through. I would still recommend it, but would have to include a warning about the noise. I have yet to try this at depths below 100'.

from New Bern, NC, US

I like this setup. I got rid of an older Mares Abyss octo and the associated hose. This makes for a much more streamlined setup. While it doesn't breathe as well as my Atomic T3 main, it's very good, and much better than that old Mares. I did, however, choose to replace the mouthpiece. The one that came on the octo was far too small and uncomfortable. But that was only a couple of bucks for the upgrade, no biggie.


Streamlined, convenient, easy breather


I bought the SS1 based on a good friend's recommendation (PADI Dive Guide professionally). It's very convenient and extremely easy to breathe from. The mouthpiece is not the most comfortable, but that's not the purposes anyway. I have no problems with this at all and love how streamlined I am. Very happy with my purchase. The quick detach system is very convenient for frequent travel.


Great Product!


Great product! I did have to get an old style hose for my Cressi Travelight BCD though because it doesn't fit the new style hose.




Bought as a replacement for the Air2 on my BC. Works great, every bit as smooth and easy as the Air2 was but now with 2 year service interval. Love Atomic regulator quality and reliability and this does not disappoint.


great octo


I had an issue connecting this to my Mares Dragon BC for the fact that the BC was wired different then the directions giving to install the Octo. But got it done and works great.

Questions & Answers Powered by TurnTo®

Questions about this item:

Shopper  Why Did You Choose This?
Hanford G  trying to clean up my rig and removing 1 hose streamlines my setup and allows for more options to store additional items during a dive
RICK R  best integrated octo out there! Quality throughout.
Shopper  Does it come complete with corrugated hose? If so what's the length of the corrugated hose?
stephen s  Yes. Just over 20in
louay a  Mine didn't come with one
ADRIAN A  The hose should come with the BC. However, it shoud come with the fitting for the hose.
Robert H  Nope. The hose should already be attached to your BCD. With this product, you get the octo and conversion parts to adapt the octo to various BC hose sizes. In my case (Zeagle Stiletto), no conversion bits were required. I just screwed the regulator onto the hose. I highly recommend this product. While it doesn't breathe as well as my Atomic T3, it's better than what I had, and you get to eliminate a hose and hanging octo to boot.
David W  No, it is the inflator/reg unit and the low pressure hose only. It has fittings to connect it to all diameters of corrugated hose, but doesn't come with that hose itself
Steven F  This does not come with the bcd hose. In the box there are several adapters (depending on hose size) to link the bcd hose to second stage. Also in the box is a atomic low pressure hose which attaches to the first stage regulator.
Luis Arturo T  Hello, no corrugated hose, just connectors of different sizes for your hose of the bcd
Christopher S  No, it has adapters to attach to your existing BCD inflator hose.
Jason S  Will this product work with the Aqualung Dimension i3/i3 system?
Thomas L  Yes it does. I have the i3 and the SS1. Works great. I prefer it as it keeps my kit nice and tidy close to my body. I still use the BCI on the i3 as my primary method.
Thomas L  I did have to get a different tubing to connect the SS1 to the BC correctly, but I can't recall exactly what I did. I am pretty sure i learned how from some forums I found googling.
LIZBETH S  I would call manufactor
