<p>Turcon&reg; Roto L from Trelleborg Sealing Solutions is featured in this video. It is the first ever active seal that seals only when required. This reduces energy consumption and increases seal-life dramatically. In central tire inflation systems for example Turcon&reg; Roto L seals only when the tire is pressurized. Nearly zero friction at no pressure and extremely low friction under pressure load makes tire pressurization on the go a reality.
