Inflatable sealing rings are actually easy to understand. When it comes to sealing rings, people easily think of O-rings, a round rubber ring. So the inflatable sealing ring is actually similar to it, the principle is to make the sealing surface contact to achieve the sealing effect.

You can understand the inflatable sealing ring as a 'non mainstream sealing ring'. Compared to O-rings, inflatable seals have different cross-sectional shapes and various styles, all of which are hollow. Most inflatable seals end up in a closed loop, forming a hollow state. Then, an air nozzle is installed at a certain point, which can be made of metal or rubber and can be used to inflate or deflate the inflatable seal.

The components of this small inflatable sealing ring are still the same, with an inflatable nozzle added to the hollow inside.

The difference lies in the processing technology. Because the inflatable sealing ring is relatively small and has strict shape requirements. So we cannot use the same joint process as large inflatable sealing rings. Small inflatable sealing rings often use integral vulcanization process, which not only produces inflatable sealing rings with exquisite appearance and no joints, but most importantly, the size is more accurate.
