It features an all stainless steel shell, as well as a stainless sideblock, helmet ring, handle, and other key components. The SuperFlow® 350 is standard on this helmet. The advantages of this stainless steel helmet include the following: -Rugged helmet shell and other components -No refinishing required if the surface is scratched or gouged -Elimination of threaded inserts for securing port retainer to helmet shell
Weight: KM 37SS - 30.96 pounds
Helmet Shell: Stainless Steel
Control Knobs: Polyurethane
Face Port/Lens: Scratch Resistant Polycarbonate
Neck Dam: Neoprene. Optional latex neck dam available

Recommended Lubricants: 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 equivelent may be used for helmet and mask components that are used with gas mixtures containing less than 50% oxygen.
Regulator: The SuperFlow 350 regulator on the Kirby Morgan 37SS offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets all current U.S. Navy and European diving standards.
Cage Code: The cage code for identifying KMDSI products for U.S. government purposes is 58366.
CR Standards: These helmets meet or exceed all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.
CE Approved: The KM 37SS helmet is CE Approved.
CE Certification: The Kirby Morgan 37SS 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 regulator SuperFlow 350 and oral nasals P/N 510-690 and P/N 510-747 (now standard).
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.
