More Information
	Maintenance and Repair Bulletin #8 November 8, 2025 Recommended attention is advised for all 455 Balanced Regulators. Whether not in service or actively used in dive operations, all 455 regulators should be inspected. However, a new 455 from the factory that has NOT been disassembled does not need to be inspected. Features Air Train: The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate. Auxiliary Port: 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. Handle: Removable Grip and handle. Handle can be removed without breaking seals, making it quick and easy to attach accessories. Nose Block: 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. 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: 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. The 455 Balanced Regulator: The 455 Balanced regulator sets a milestone in surface supplied breathing performance and is compatible with all Kirby Morgan Helmets and Band Masks that feature the SuperFlow® 350 regulator. The regulator body is made of 316 stainless steel, as are all its other metallic components. Whisker Wings: Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise. Specifications Weight: 31.09 lb. Helmet Shell: Stainless steel Control Knobs: Polyurethane Face Port/Lens: Scratch resistant polycarbonate Neck Dam: Neoprene. Optional latex neck dam available O-rings: Buna-N Head Cushion: Nylon bag filled with #4 Polyester foam 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 equivalent may be used for helmet and mask components that are used with gas mixtures containing less than 50% oxygen. Regulator: The 455 balanced regulator on the KM 97 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. Cage Code: The cage code for identifying KMDSI products for U.S. government purposes is 58366. Notes The minimum operating temperature recommended for this helmet is 34 °F (1 °C), without the use of the water shroud P/N 525-761 and hot water. Without a hot water and the shroud system, the diver may be subject to hypothermia due to cold gas inspiration temperatures. 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.
