Product Information

The Atomic Aquatics Z2 Second Stage is a standalone second-stage regulator with a gray housing and a 32-inch hose, built for divers who need a replacement or spare second stage that works with Atomic Aquatics regulator systems.

Who it is for

This second stage suits divers who already own an Atomic Aquatics first stage and want a spare, a backup, or a direct replacement second stage rather than a full regulator set. The 32-inch hose length gives flexible positioning for scuba diving and underwater exploration, and the gray housing is built for straightforward use and maintenance.

Key details

  • 32-inch hose length
  • Gray housing with a corrosion-resistant finish for durability in saltwater environments
  • Ergonomic inhalation control and intuitive purge for easy underwater use
  • Balanced airflow design supporting stable performance across depths
  • Second stage only, designed to be compatible with Atomic Aquatics regulator systems
  • MPN: 02-0350-3P-S

Compatibility and sizing

This is a second-stage-only unit, intended for use with compatible Atomic Aquatics regulator first stages rather than as a complete regulator set. Confirm fit with your existing first stage before ordering.

DiveCatalog.com is an authorized Atomic Aquatics dealer and a dive shop in Irvine, California, serving divers since 2003. Call or chat with our team at 888-701-4017 if you have questions about fit or compatibility with your current regulator setup.
