Apeks MTX-R Regulator Set 

The Apeks MTX-R First and Second Stage Regulator Set plus Octopus is based on the MTX military regulator and is a super tough, rugged, high performance, go anywhere regulator. The MTX-R has excellent cold water performance and has a greatly reduced risk of free flow. This has been achieved by improving several areas, including an innovative endcap solution that solves a long-challenged reality for cold-water divers of first stage freeze up.

This regulator is designed to meet all aspects of the NEDU (Navy Experimental Dive Unit) military requirements for diving in very cold water. The Apeks MTX-R is highly reliable and very easy to service out in the field. Unique over-balanced diaphragm design as the diver descends, the over-balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.

Compact environmentally dry sealed diaphragm system completely-eliminating the maintenance issues associated with silicone, oil or grease filling. Break through, innovative over-molded first-stage endcap and environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also, protects the first stage from impact damage. Easy to grip DIN hand-wheel, only requires one hand to release. 5 x 3/8" UNF (Unified National Fine) medium pressure ports and 2 x 7/16" UNF high pressure ports. The 5th 3/8" UNF medium pressure port includes a protective bumper when not in use.
