Assembled using oxygen compatible materials and lubricants, this Dive Rite O2 Deco Regulator is suitable for Oxygen Service without the need for additional preparation. The Dive Rite Deco Regulator is a compact, lightweight option for an accelerated decompression regulator. A value priced unbalanced piston DIN first stage and adjustable second stage delivers performance tuned for shallow water decompression. An orthodontic long bite mouthpiece reduces jaw fatigue on longer deco obligations. The package includes a Mini-SPG in PSI, S/S bolt snap with hose clip retainer, DIN cap, and comes assembled by Dive Rite with a green faceplate cover and green {40 in | 1 m} hose. The flex hose makes hose management easy and comes standard with the O2 Deco Regulator setup. Because of the piston first stage, the Dive Rite Deco Regulator is ultra reliable but the unbalanced design is not intended for use deeper than {50 ft | 15m} on an appropriate gas mix. We also note that this first stage is NOT compatible with MiFlex Brand HP hoses.
