Air-Lock, Inc., a wholly owned subsidiary of David Clark Company t- the latter offering Headset Communication Systems for High-Noise Environments. Air-Lock specializes in the Air-Lock connectors and sealed bearings that have been critical components of pressure suits worn by pilots of virtually all high-altitude aircraft since the late 1940s. Importantly, all spacesuits worn by NASAâs Gemini, Apollo, Skylab, and Shuttle astronauts have employed Air-Lock hardware. The full-pressure âbubbleâ helmet originally developed by Air-Lock for the Apollo program continues to be used with the Shuttle Extravehicular Mobility Unit (EMU). Formed from seamless polycarbonate material using proprietary equipment and processes, this helmet provides a full-pressure head enclosure, full-visual field optical transparency, and impact resistance. The quality and reliability of Air-Lock products is perhaps best epitomized by the polycarbonate âbubbleâ pressure helmet and visor assemblies it developed for the Apollo spacesuit program and continues to provide Shuttle and International Space Station space-walking astronauts. The range of Air-Lockâs products has expanded over the years to include specialized hardware for a wide variety of life support systems, including survival kits, oxygen systems, life rafts, and chemical-biological protective systems. Similarly, the variety of materials processed at Air-Lock has expanded to include conventional and exotic metals, thermoplastic and thermoset resins, composites, optical transparencies, coatings and elastomers - hardware of the highest quality and reliability for use in increasingly demanding and hazardous env
