Apeks XTX50 + XTX40 Octo Din Regulator Set
The XTX50 and DST combination gives you adjustable breathing controls and a rotating first-stage turret. It is a flexible platform for arranging hoses around your diving equipment, with the selected configuration determining the exact first-stage ports and supplied components.
Features and benefits
- Balanced gas delivery. The over-balanced diaphragm mechanism helps manage the supply to the second stage as diving conditions change.
- Adjustable breathing feel. The inhalation-effort control lets you tune the adjustable second stage within its operating range.
- Venturi control. Select the appropriate setting for surface handling or diving to help manage free-flow tendency.
- Environmental protection. The sealed first-stage chamber helps keep water and contaminants away from its working mechanism.
- Rotating hose turret. Arrange the low-pressure hoses around your preferred equipment layout.
- Comfortable mouthpiece hold. The Comfo-Bite palate bridge helps support the second stage without a hard bite.
- Progressive purge. Control the purge response with the amount of pressure applied to the button.
Setup and compatibility
Connection: DIN. Choose the fitting that matches your cylinder valve and its pressure rating. A fifth-port upgrade is optional and sold separately unless expressly included in your selected configuration.
The XTX40 octopus has Venturi control; the separate inhalation-effort adjustment belongs to the primary XTX200 or XTX50 second stage in the set.
