The Apeks XTX50 Oxygen Regulator is for the discerning diver who wants the benefits of a feature-rich regulator at a moderate price. This popular regulator has four medium-pressure ports all mounted on a rotating turret. This results in optimal hose routing while eliminating sharp bends in the hose. Also available is an optional 5th port is available for sidemount or twin cylinder set ups. This is ideal to configure for use as stage bottles and pony bottles using high Oxygen content gases.

Compatible to Oxygen to 100% right out of the box.  The over-balancing feature of the Apeks XTX50 First stage allows the medium pressure air in the hose to increase at a rate faster than ambient pressure resulting in superior performance.
