SPACE SUIT OXYGEN HOSE SEGMENTS FLOWN AND USED DURING APOLLO XII.
Flown to the Moon on Apollo XII. Two samples, approximately ¼ inch and a 1 ½ inch curved section of one the Apollo XII space suit oxygen hose assemblies. Both are mounted onto an 11 by 8 inch display certificate with a color image of the Apollo XII crew. There are multiple captioned illustrations of how the oxygen hose assembly was used during the mission. Sample number 707 of 1500. With copies of NASA/MSC transfer papers to the Smithsonian's National Air and Space Museum (NASM) and NASM deassession papers.
The certificate reads in part: "The attached material is a section of the Apollo Space Suit Oxygen Hose Assembly and was flown to the Moon on APOLLO XII during November 14-24, 1969. Apollo XII was the second of six successful lunar landing missions during the Apollo program. The hose material was constructed from a flexible silicone rubber material and supplied breathing oxygen to the Apollo XII crew members during the Saturn V launch and the command and lunar module docking phases. They were also available for space suit emergency support during the entire flight. While not connected to the space suits, the hoses provided a conduit of fresh air to the cabin. This material was in the command module Yankee Clipper and made 45 orbits of the Moon. After the Apollo XII mission, parts of the oxygen hose assemblies were analyzed. The hoses were cut into six inch segments, and some were then split in half. The attached materials are shavings from this procedure."
