The world's first "green" regulator! Compared to other metals that require surface coating and finishing, our stainless steel is more environmentally friendly, and our Type 316 stainless steel has twice the strength and corrosion resistance of brass. The all-stainless first stage body features a pivoting low-pressure cap with 5 ports and 2 high-pressure ports and is sealed against environmental influences. The second stage also houses lightweight titanium components and features our patented Atomic Aquatics stainless steel comfort swivel hose.
