- Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing.
- The fan-shaped supporters, in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring.
- The sealing gap is larger than D-type , and a wider range of steel pipe specifications can be used for the same specification sealing ring.
