Abstract
The method of repairing leaks in a bundle of hollow capillary fibers of a diffusion device disposed in a housing comprises temporarily sealing one end of the bundle of fibers, applying a curable sealant paste to the other end of the bundle of fibers, and then applying a suction pressure to the flow path which passes through the bundle on the exterior of the fibers. Wherever a hollow fiber has a leak, the suction pressure will be transferred to the interior of the fiber, to individually cause the fiber to suck the curable sealant paste into its interior, thus blocking the fiber and preventing flow through it.
