This pressure suit hose was used with a spacesuit worn by astronaut Walter "Wally" Schirra during training sessions prior to his Sigma-7 flight in October 1962.
In 1959 NASA selected the silver colored nylon suit that B.F. Goodrich developed from the US Navy MK-IV full pressure suit for use in Project Mercury. The suit, which consisted of four basic components, the suit torso, helmet, gloves and boots, was worn with a long undergarment.
NASA transferred this suit to NASM in 1972.
