XTX50 Second Stage

The classic and popular Apeks XTX50 Second Stage with a breathing effort adjustment for precise control of breathing effort.

XTX50’s second stage can be converted from a right-handed hose configuration, as supplied, to a left-handed one. This feature is known as the Reversible Venturi System. Changing the regulator to a left-handed configuration is quick and simple and can be performed by any Apeks Authorised Service Technician.

The XTX50 Second Stage incorporates the feature of Diver Changeable Exhausts system. This system allows the diver to change from a small exhaust tee to a large one. This gives the user a choice of the wider exhaust tee for minimal bubble interference, essential for underwater photography, or the narrow exhaust tee for a smaller compact and comfortable set-up.


The Apeks XTX50 second stage incorporates a two-shot high-strength composite front cover, improving the durability of the most vulnerable part of the demand valve.

The ergonomic Venturi lever of the Apeks XTX50 Second Stage has been designed to reduce the amount of grit ingress.

A silicone exhaust valve has been used on the Apeks XTX50 Second Stage, improving breathing performance.
