Z2 First and Second StageThe combination of performance, ergonomics, features, and materials found in the Z2
adds up to our most cost-efficient regulator option, without compromising performance
or durability. The chrome-plated brass first stage comes with a fixed 7-port cap and two
high-pressure ports. The second stage houses corrosion-resistant zirconium coated
brass and titanium components. Environmental sealing is optional for this system and it
comes standard in grey or blue.
