PTFE V-ring is short for Polytetrafluoroethylene V-ring. It is a kind of ring with a shape of V.PTFE is a synthetic fluoropolymer of tetrafluoroethylene that finds numerous applications. PTFE is hydrophobic: neither water nor water-containing substances are wet by PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction against any solid.
A V-ring consists of support ring, seals and pressure ring. It has a standard Angle of 90 °and 60 °in special occasion.
Since PTFE can be used as a lubricant, PTFE V-ring can reduce friction, wear, and energy consumption of machinery. Stable and nontoxic, it is widely used in machines.
