The Apeks MTX-R Sidemount Regulator Set is an extreme cold water regulator and accessory package that includes everything you need to create a sidemount configuration. The MTX-R regulators were development from an Apeks Military regulator to surpass the US Navy extreme cold water test, the requirements for which go way beyond those laid out for normal cold water rating standards.
The first stages use the typical environmentally sealed balanced diaphragm design with a swivelling turret and fifth low pressure port on the end of the turret. The body is finished with a stylish satin chrome coating. Fins have been incorporated into the body design to help dissipate the cold generated by the first stage, helping to reduce the risk of ice formation and cold related freeflows.
The second stage continues the cold water performance with a large inlet heat exchanger and a full metal valve barrel. The second stage is tough and robustly made with a wide exhaust deflector and fitted with the typical Apeks regulator mouthpiece for excellent comfort and hygienic properties
