An extrusion is a manufacturing process in which a material (such as metal, plastic, or food) is forced through a die (a tool with a specific shape) to create a specific shape or cross-sectional profile. The material is typically heated and pushed through the die by a screw or ram. The resulting shape can be a rod, tube, or other shape depending on the die used. Extrusion is used in a wide range of industries, including plastics, metals, and food production.
PTFE is an acronym for Polytetrafluoroethylene, which is a synthetic fluoropolymer of tetrafluoroethylene. It is a highly non-reactive, heat-resistant, and chemically resistant plastic often used in a variety of industrial and consumer applications. Some common uses include non-stick cookware, Gore-Tex fabric, and electrical insulation. In this case, it is used to produce PTFE Rod or tube that can then be converted into PTFE parts including seals.

What is the difference PTFE tube and bar?
Both PTFE tube and bar are extruded. The difference is many of the finished product made from them do not require solid PTFE. If your able to reduce the amount of the PTFE required, you will also reduce the cost of your part. The second issue is if you can use a bar stock that has the correct inside dimension you also have reduced the machine time required to produce your part.
