ABSTRACT:
Very low moisture o-rings are prepared by placing standard o-rings under vacuum in an inert atmosphere for a period of time sufficient to achieve a desired outgassing rate. Heat is not applied. While the o-rings are under vacuum, moisture is removed from the o-rings via diffusion transport.
