Product Information
The Apeks Sidemount Regulator Package pairs the Apeks MTX-R Sidemount Set with an Apeks Tek Gauge SPG so you have a complete, matched setup ready for a sidemount cylinder configuration. The MTX-R Sidemount Set is built around the cold-water MTX-R platform, with two first stages configured for left and right sidemount cylinders and second stages fitted with sidemount-appropriate hose lengths, all in an Imperial Black/White configuration.
Each MTX-R first stage is environmentally sealed to keep out silt and contaminants and uses heat exchanger construction to resist freezing in cold water, while Comfo-bite mouthpieces on the second stages help reduce jaw fatigue on longer dives. The result is a sidemount-specific regulator set designed to hold up in cold, silty, or overhead environments like caves and wrecks.
Rounding out the package is the Apeks Tek Gauge SPG with hose, a chrome-plated pressure gauge with a black face and luminescent numbers and hands that glow in the dark. That black face is designed to cut glare and preserve night vision in low light, which fits the same cave and wreck diving this MTX-R set is built for. It reads on a 0-360 bar/0-5000 psi scale with a 300 bar/4350 psi max working pressure, behind a tempered glass, 52mm/2" face, matching the Imperial gauge setup of the MTX-R Sidemount Set.
