If you have ever travelled the famous London Underground also known as “The Tube”, the words “Mind The Gap” may yield an important safety warning. But ask yourself, what if you didn’t have to “Mind The Gap”? What if safety concerns while boarding and exiting were a thing of the past? Seal Master Corporation has engineered a unique solution to this problem: inflatable pneumatic seals. A Seal Master inflatable seal will inflate upon the train’s arrival and deflate during takeoff, eliminating the gap and safety concern and solving Platform Train Interference. This unique solution is only offered to you by Seal Master Corporation and is custom engineered to your specific application.
