Sulfuric acid can be a tricky substance to deal with from a compatibility standpoint because its corrosivity changes significantly with concentration, temperature, and velocity and not always in the expected way. Many rubbers have resistance to sulfuric acid as long as the temperature limits are not exceeded. The formulation of the rubber can have a significant impact on performance so careful material selection is required to achieve satisfactory results. Depending on the specific problems you are having, a different rubber, coating, or material of construction may need to be considered.
