Apeks DST / XTX50 Regulator
The XTX50 regulator brings the high performance of Apeks’ top end regulators down to a more affordable budget, and is our most popular Apeks regulator. The DST first stage gives you plenty of ports – 2x HP and 4x LP as standard, on a swivel turret for perfect hose routing. As you’d expect from Apeks it is an over balanced diaphragm based reg and it’s environmentally sealed first stage means the XTX50 can be used in the coldest of waters.

Apeks XTX40 Octopus
The Apeks XTX40 mirrors the build quality and performance of the primary XTX40 2nd stage regulator. It’s pneumatically balanced design ensures it can deliver consistent, effortless breathing no matter your tank pressure.
