Apeks XTX50 Sidemount Regulator Set (Imperial Gauges)

By Apeks | Complete Factory-Matched Sidemount Kit | Dual DST 1st Stages with 5-Port Turrets | Imperial PSI Gauges

Take the guesswork out of configuring your sidemount breathing apparatus with the factory-assembled Apeks XTX50 Sidemount Regulator Set. Engineered specifically to streamline hose routing, reduce clutter, and ensure unmatched breathing performance in demanding open-water and overhead environments, this complete package contains every regulator, hose, gauge, and hardware component required for dual-cylinder sidemount diving.

At the core of this system are two over-balanced Apeks DST first stages, each fitted with a rotating swivel turret and the upgraded 5th axial low-pressure port. Paired with two pneumatically balanced XTX50 second stages, short-stem imperial PSI submersible pressure gauges, and dedicated sidemount hose lengths, this system delivers effortless breathing and optimal hose management straight out of the box.
