The invention belongs to the field of mechanical assembly, and particularly relates to a visual sealing element compression ratio measuring device and method.The device comprises a fastening bolt, an upper assembly flange, a sealing element, a lower assembly flange, a fastening nut and a standard color contrast band; wherein the upper assembly flange and the lower assembly flange are connected and fixed through the fastening bolt and the fastening nut, the sealing element is installed on a platform of the lower assembly flange, the fastening bolt and the fastening nut are adjusted to press the sealing element, the color of the sealing element is observed after fastening, the color is compared with a standard color contrast band, and the compression ratio of the sealing element is confirmed. The flange fastening step is simplified, use of measuring instruments such as vernier calipers, depth gauges and feeler gauges is avoided, the requirement for personnel qualification is low, and the working efficiency and
