Type 4 Liners


Type 4 liners weigh one-third the weight of aluminum liners. They can be wrapped in Carbon Fiber or other materials. Composite over-wrapped pressure vessels with type 4 liners reduce fueling system weight. The reduced weight leads to better fuel economy, increased range, and increased storage capacity. Common uses for type 4 liners include aerospace, bus, and trucking applications. Type 4 liners are corrosion resistant which ensures longevity and reliability.
