What's in the box
For the diver who wants an all metal helmet, the new stainless steel Kirby Morgan® 77 helmet is the way to go... It features an all stainless version of the Rex® regulator, as well as a stainless sideblock, helmet ring, bent tube, handle, and other key components. The Rex® Quad Valve® Exhaust System is standard on this helmet.
The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
The auxiliary port will allow for future add-ons and modifications to the stainless steel helmets. It is located on the port side of the shell as shown below.
Defogging Steady Flow Valve
Provides an additional flow of gas into the helmet for ventilation and defogging.
Emergency (EGS) Valve
Emergency (EGS) Valve supplies backup breathing gas to the diver. This valve is an integral, built in part of the stainless steel sideblock.
Gas Supply Non-Return Valve
Commercial Rated, It prevents loss of gas pressure in the event of umbilical damage.
Removable Grip and handle. Handle can be removed without breaking seals, making it quick and easy to attach accessories.
Nose Block Device
Nose Block Device allows the diver to block the nose to equalize ears.
Rapid Change Modular Communications Systems
Because the module is easily removed the helmet, repair or replacement of communications parts is quick and trouble free. It is available with either a male waterproof connector or a bare wire post connection.
Full adjustment balanced piston is a breakthrough design that exceeds all requirements of all government or other testing agencies. It has the best work-of-breathing performance when compared to ANY other commercial diving regulator.
Silicone Oral Nasal Mask
Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
Stainless Steel Shell
After x-ray inspection, each 316 stainless steel shell, is precision CNC machined to tight tolerances, to ensure proper fit to all other mating parts. The shell is durable and easy to maintain. Easily cleaned using a Scotch Brite or similar type cleaning pad.
Stainless Steel Side Block
Multi use side block has additional ports built in to provide controlled air flow, if needed. The stainless steel sideblock has a built in EGS.
Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.

All helmets and masks are lubricated at the factory with Christo-Lube. Kirby Morgan recommends Christo-Lube or Tribolube for all gas train components. Dow Corning 111 Silicone or equivalent may be used for helmet and mask components that are used with gas mixtures containing less than 50% oxygen.
The Rex regulator on the Kirby Morgan 77 offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets or exceeds all current U.S. Navy and European diving standards.
The cage code for identifying KMDSI products for U.S. government purposes is 58366.
This helmet meets or exceeds all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.
The KM 77 helmet is CE Approved.
The Kirby Morgan 77 helmet has been tested and conforms to the performance requirements as set forth in Annex II of Directive 89/686/EEC and, as far as applicable, the EN 15333-1:2008/AC:2009 (class B). It is fully CE marked with demand valve REX.
The minimum operating temperature recommended for this helmet is 37 degrees F, only in regards to regulator performance. At the time of this writing, no hot water shroud is available for this helmet for heating the diver's breathing gas.
Without a hot water shroud, the diver may be subject to hypothermia due to cold gas inspiration temperatures. Kirby Morgan makes no physiological recommendations regarding minimum safe operating temperatures for divers using this helmet.
Usually the greatest danger of demand regulator icing will be encountered on deck when the surrounding air temperature is less than 32°F (0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and the addition of moisture from the diver's exhalation coming in contact with the topside air temperature.
Recommended overbottom (OB)gas supply pressure for best performance at depths are calculated by the formula (fsw x 0.445+14.7) + recommended p.s.i. g.
