Tubular inflatable expansion seal, made of high-quality, environmentally friendly silicone rubber material, forming a hollow sealing strip. It expands and deforms upon inflation, quickly contracts and returns to its original shape upon deflation, used to seal gaps in machinery with special requirements.
Characteristics of inflatable expansion seals
1. Inflate and seal both ends of the expansion seal for use as a straight airbag.

2. Connects to circular inflatable seals of different diameters, and can also be assembled into square right-angle inflatable seal frames.

3. Design hollow cross-sectional shapes for different circular bodies based on sealing gap size, fluid pressure, expansion/contraction frequency, etc. Shapes include round, rectangular, square, trapezoidal, D-shaped, C-shaped, V-shaped, and M-shaped, etc.

4. Air-filled sealing rings, like solid rubber seals, can achieve radial and axial sealing for equipment.

5. The inflation port is equipped with a metal valve or a flexible hose connection for intake and exhaust.

6. Colors: Natural silicone, porcelain white, red, blue, yellow, gray, black, etc.

7. Temperature Resistance: -60 to 280 degrees.

8. Inflating Pressure: 0.05-1.0 Mpa, varies depending on the cross-sectional size, dimensions, and wall thickness.
