Inflatable Expandable Sealing Ring – Leave your stringent sealing issues to Qingtu Rubber  

Inflatable expandable seals are made from environmentally friendly silicone rubber with low-temperature resistance down to -50 degrees Celsius and high-temperature resistance up to 200 degrees Celsius, suitable for industrial use.Sealing required. This inflatable silicone rubber sealing ring and its sealing structure feature simplicity in design, ease of installation, excellent sealing performance, and the ability to achieve self-sealing in both axial and radial directions. The outer edge of the inflatable sealing ring has a guide positioning ring, and when the upper and lower lips on the inner edge are closed, they form a complete closed hollow ring. Upon inflating the hollow ring with high-pressure gas (or liquid) inside the pressure vessel, it expands outward, generating self-tightening properties in both axial and radial directions. The greater the internal pressure of the pressure vessel, the stronger the self-tightening effect and the better the sealing performance.
