		PST's steel CNG cylinders are manufactured from a single disc of high strength steel which produces the lightest cylinder available. These cylinders have a continuous integral bottom, uniform side walls and precision drilled and tapped threads. PST steel CNG cylinders are designed and produced to a variety of specifications including DOT FMVSS 304, CAN B51 part 2, NZS 5454, DOT 3AA and others. Please contact the factory for details. If weight is a consideration, PST's fiberglass hoop wrapped steel liner CNG cylinders are up to 40% lighter than plain steel cylinders and more space efficient than aluminum. Featuring our deep drawn seamless steel liner, these cylinders have twice the tensile strength of aluminum yet are half as thick.
