CYLINDERS
TUFFSHELL® all-composite Type 4 cylinders are simply the best combination of safety, efficiency and durability available in the market. Their lightweight construction — 30% the weight of steel — improves vehicle range, payload and handling. Reduced fuel consumption is good for the environment and even better for your bottom line. You’ll find TUFFSHELL® cylinders everywhere, as they are used by many well-known car manufacturers. You’ll also find them in 80% of European and 85% of North American transit buses, including Los Angeles, Atlanta, New York City, Washington D.C. and Vancouver. Plus, they are installed in a variety of commercial vehicles, including Class 8 trucks, refuse trucks, concrete mixers and delivery trucks.
We make two types of TUFFSHELL® cylinders:
  • lightweight cylinder with lightweight carbon/glass fiber hybrid wrap
  • even lighter weight cylinder with all carbon fiber wrap
Superior Cylinders
  • High-strength, super-tough construction reduces impact damage and fatigue
  • Dome protection against abrasions and scuffs
  • Polymer liner is corrosion-free
  • Precision-machined valve interface ensures leak-free operation
  • Available in both strap mount and boss mount designs for maximum packaging efficiency
  • Expansive list of standard sizes available for vehicles big and small
  • Designed to be maintenance-free with reduced inspection costs
  • Boss mount design isolates cylinders from torsional forces
Superior Safety
TUFFSHELL® cylinders come equipped with state-of-the-art pressure relief devices. If the ambient temperature surrounding the cylinder reaches 230°F/110°C, the cylinder contents will be vented into the atmosphere. TUFFSHELL® cylinders have proved their durability when tested in the field by severe accidents.
