Optimum Awarded Patent for Type 4 Boss Cylinder


Optimum Composite Technologies was recently awarded its patent for the Type 4 Boss from the United States Patent and Trademark Office. The company is working on certifying a type 4 CNG tank using this technology and plans on having one ready for market by the start of 2017.

Optimum has been using this technology for several years on products ranging from their small cylinders used for R&D Testing to high pressure Hydrogen tanks. The polar boss can withstand pressures beyond 25,000 psi.

“Having a reliable leak free polar boss is one of the major obstacles in designing a successful type 4 cylinder,” commented Chief Technical Officer Mike Olson. “We feel extremely confident in and have proven its reliability.”
