APEKS DST 1ST STAGE ONLY

Swivelling smarts. Depth muscle. Proven simplicity.

The Apeks DST First Stage is the versatile, heavy-hitting 1st stage trusted by divers who want performance with practical routing logic.

Stronger the deeper you dive

Its over-balanced diaphragm design actively increases medium-pressure delivery faster than ambient pressure rises on descent. The reward? More stable airflow, improved second-stage response, and a first stage that keeps gas delivery confident and consistent as depth increases.

The turret that tidies your hoses

4 medium-pressure ports mounted on a smooth 360° rotating turret make hose orientation cleaner, safer, and dramatically more intuitive. Dual HP ports add flexibility for SPG and transmitter fitting, while the angled geometry keeps hose bends gentle and routing sharp-looking — whether you’re building a streamlined single-cylinder rig, adding suit-feed bottles, or optimising sidemount and stage hose exits.

Cold-considered internal sealing

An environmental dry seal system isolates the spring chamber from water, silt and contaminants, stopping ice formation and debris ingress at the source. It’s why divers trust DST first stages in UK waters where temperatures drop, visibility fades, and rinse buckets aren’t always instant.
