PTFE Rod

PTFE Rods are part of our extensive range of polymer rods. With 166 variations available, these fluoropolymer rods offer an exceptional combination of properties including excellent chemical resistance, low friction, thermal stability and electrical insulating abilities. Typical applications for PTFE rods include being used as bearings, valve seats, seal rings, and in other demanding chemical or high temperature environments where friction reduction, corrosion resistance and durability are critical. These versatile rods can also be machined into custom parts and components.
