Inflatable Seals

Inflatable Seals

Advanced Sealing Solutions for Critical Containment & Process Applications

JMT Rubber manufactures high-performance Inflatable Seals designed to provide reliable, leak-proof sealing in applications where conventional sealing methods are not sufficient. Engineered from premium-grade silicone and elastomer compounds, our inflatable seals offer superior sealing efficiency, flexibility, and durability for pharmaceutical, biotechnology, food processing, medical, packaging, and industrial applications.

When inflated with air or other suitable media, the seal expands to create a uniform sealing force, ensuring effective containment, dust control, pressure retention, and contamination prevention.

What are Inflatable Seals?

Inflatable Seals are hollow elastomeric profiles designed to expand when pressurized. Once inflated, the seal fills gaps between mating surfaces and creates a highly effective seal, even in applications involving uneven surfaces, movement, or varying tolerances.

Unlike conventional gaskets, inflatable seals can be activated and deactivated repeatedly, making them ideal for doors, hatches, isolators, chambers, dryers, and containment systems.
