Apollo A7L spacesuit oxygen hose. Flexible hose measures almost seven-feet long and features two one-inch diameter rubber hoses feeding into a single 2.5″ coupling. Ends of each hose are labeled “R,” and the covering of the coupling is labeled “R. E. Darling Co., Inc.” Hose is contained in its original clean room packaging, which has been opened. In fine condition. The A7L suits consisted of an inner Pressure Garment Assembly (PGA) that was pressurized with oxygen for breathing, and an outer Integrated Thermal Micrometeoroid Garment (I/TMG) that protected the astronaut from temperature extremes and hypervelocity micrometeoroid punctures while on the lunar surface. Connectors for the primary and back-up oxygen supply, electrical supply, and water for space suit cooling were on the front torso area of the A7L suit.
