Description

Apollo A7L space suit oxygen hose assembly, designed for astronaut life support aboard the Command Module

Apollo in-cabin oxygen hose assembly for the A7L space suit, measuring approximately 75″ long, featuring two flexible white rubber hoses with 1″-diameter blue-and-red anodized Air-Lock connectors for the A7L space suit at one end, terminating in a single 2.75″ coupler. The right-angle Air-Lock connectors are marked as "PN-4247R, SN-154" and "PN-4247B, SN-156." The hose assembly is sheathed by two layers of white Beta cloth. In fine condition, with overall wear and some scratches to the connectors.

The Apollo 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. These hoses were intended for application within the Apollo Command Module to connect an astronaut's pressure garment assembly to the Environmental Control System (ECS) and provide breathable atmosphere during intervals when cabin atmosphere may be lost or at risk of loss.
