CPI offers the most extensive line of lightweight aluminum cylinders in the industry. CPI's Aluminum cylinders are 40% lighter that steel cylinders. With an average wall thickness twice that of their steel counterpart, aluminum cylinders absorb more impact energy and have a greater resistance to damage from rough handling or accidental dropping. Aluminum cylinders are lower maintenance and have a more attractive appearance. Most importantly, they will never rust like a steel cylinder.

    Cpi's composite cylinders take the term "lightweight" a step further. Composite cylinders are produced using ultra thin walled aluminum liners reinforced by both helical and hoop wrapped continuous fibers. The result is lightweight, low profile, high performing cylinders that can be up to 70% lighter that steel and 30% lighter than conventional aluminum cylinders.
