- Made of High-Density Polyethylene (HDPE) these high-quality liners are light weight and corrosion resistant.
- Type 4 liners weigh roughly 2/3rds less than Type 1 and Type 2, and much lighter than Type 3 cylinders.
- The liners light weight result in more affordable transportation, work and shipping costs.
