Koroseal: A rubber substitute

Koroseal, a plastic substitute for common rubber tubing for hospital use, is presented. Its advantages are: (1) It is almost indestructible to ordinary sterilizing methods. (2) It is transparent, thus facilitating the administration of intravenous fluids and at the same time making the cleansing problem much simpler. (3) It is radiopaque and can be manufactured in whatever size seems most desirable. ∗ ∗ Koroseal tubing used in this work was supplied through the courtesy of the United States Navy and the B. F. Goodrich Company, Akron, Ohio.
