Apeks XTX20 UST 1st Stage

The unsealed version of the Apeks’ classic DST 1st stage offers exactly the same incredible performance and features in a lighter and more affordable package.

The XTX20 UST is balanced, so breathing is consistent no matter how much air is left in your tank. With 2 high-pressure ports and 4 low-pressure ports, the UST allows you to easily connect and route all of your dive gear while the swivel head allows for superior kink free routing.

Because the XTX20 is unsealed it’s suitable for warm water diving of temperatures above 10*C.


  • Balanced Diaphragm - The Balanced diaphragm ensures that breathing is always easy, even when your tank is running low on pressure, unlike unbalanced 1st stages that require more effort when air is running low.
  • Warm Water Ready - Unlike the DST 1st stage that the XTX20 UST shares its design with, the UST isn’t sealed. This means it’s suitable for warm water above 10*C. Because of this the UST is lighter than many sealed 1st stages.
  • Swivel Head - The UST head swivels allowing you to route your hoses optimally and eliminate kinks.
  • Easy Hose Routing - The UST features 2 high-pressure ports and low-pressure ports that allow you to easily attach and route all of your hoses.
    • 2 High Pressure Ports (7/16" UNF)
    • 4 Low Pressure Ports (3/8" UNF)
  • Optional 5th Port - A 5th optional port allows you to configure more complex scuba setups easily.

Who is the Apeks XTX20 UST 1st Stage For?

The XTX20 UST 1st stage delivers top-end performance at an excellent price. If you’re looking to technical diving in warmer climates it’s an exceptionally versatile 1st stage that’s able to hook up any dive gear you need and perform effortlessly no matter what you ask of it.
