Back-up Ring Standard Size Charts

The backup ring is used together with the sealing ring to prevent the sealing ring from being squeezed into the gap on the low-pressure side when the pressure continues to increase, so the backup ring is a filler for the sealing ring, which is not a seal in itself, but effectively improves the working pressure range of the sealing ring.
