PTFE (Polytetrafluoroethylene) is perhaps the most widely used fluoropolymer available because it has several features which make it ideal for a wide range of applications. Fluor-A-Pure™ PTFE Tubing is more flexible than all other tubing in its class, and can resist nearly all industrial chemicals. With a temperature range of approximately -330°F to 500°F, it offers the widest temperature range of the fluoropolymers. In addition, it has excellent electrical properties and low permeability. PTFE tubing is most widely used as laboratory tubing and for applications where chemical resistance and purity are essential. PTFE has a very low coefficient of friction and is one of the most “slippery” substances known. TBL Plastics offers a broad range of sizes which can be used with standard compression fittings.
