Suited for Class 8 heavy-duty and refuse trucks, 26.2 in. Type III CNG cylinder fills to rated capacity to extend route possibilities. Inner aluminum liner dissipates heat during fast-filling, which increases fuel storage capacity; promotes safety by reducing risk of flex or fracture in outer composite reinforcement if impact occurs; prevents permeation; and provides heat tolerance in case of fire. There are no filling restrictions in hot or cold weather, and and construction is gas tight.
