Works in hostile environments This line of Fluoropolymer tubing products handle gas, water and ozone sampling, heat exchangers, wastewater transfer and filtration. They resist heat and UV, and have a low friction coefficient. They can work in up to 500F (260C), and are chemically inert to work in harsh environments. They come in sizes from .004 inches ID up to 4 inches ID, and come in TexFluorģ PTFE, FEP, MFA and PFA. They can be supplied in smoothbore, convoluted or extra flexible, corrugated. In corrugated form, fluoropolymer tubing goosenecks around obstacles or turn sharp corners without restricting flow. They also have a low refractive index, making it easy to see material flowing through the tube.
