A port cover for a fluid port of ported sub with a tubular body having one or more fluid ports provided in the external wall of the tubular body. The port cover comprises: a permeable media shaped to snugly fit a void space formed by a fluid port of the fluid port in the external wall; and an adhesive adapted to fix the permeable media in the void space. The permeable media is adapted to permit migration of fluids therethrough for pressure equalization between an inner and an outer side of the external wall, and disallow migration of solid particles of a specified size in the sub through the fluid.
