The Atomic Aquatics ST1 Swivel Sealed Regulator has a stainless steel first-stage. Stainless steel delivers virtually the same corrosion resistance as titanium at a lower price. Stainless steel does not require protective chrome or nickel plating processes that can be harmful to the environment and is 100% recyclable. The first-stage is machined from solid 316-grade stainless steel.
