Rubber inflatable seals

This rubber inflatable seal is made from high-strength synthetic rubber, processed through low-temperature vulcanization and precision cutting techniques. It combines excellent sealing performance and impact resistance, and is widely suitable for industrial machinery, logistics vehicles, environmental protection equipment, and other scenarios. The product has passed ISO9001 quality certification, and exhibits outstanding weather resistance, operating stably within a temperature range of -30°C to 180°C, without fear of moisture, dust, or general chemical medium erosion.
After inflation, it rapidly expands and forms within 3 seconds, creating a uniform pressure surface with a contact pressure of 0.2-0.6 MPa. It can closely fit uneven sealing surfaces, and its sealing efficiency is 35% higher than traditional seals. The built-in high-strength fiber mesh layer has a tear resistance of 12 MPa, making it resistant to aging and damage from repeated inflation and deflation. Under normal operating conditions, its service life exceeds 6,000 hours.

We support customization for diameters ranging from 5mm to 100mm and various cross-sectional shapes, accommodating diverse needs such as container doors, reaction vessels, and cleanrooms. The quick-insert air valve design facilitates convenient inflation and deflation operations, with a volume reduction of 80% after deflation, making equipment maintenance easier. Relying on the mature production line of Tianjin Jinhang Technology, samples are delivered within 3 days, and the punctuality rate for bulk orders is 100%.
