经济、柔韧的PTFE管适用于高达500 psi（35 kg/cm²）的压力。可用于自动分析仪、柱后反应、制备级规格系统、流内取样装置以及监测生理上重要的化合物。

PTFE的最大推荐操作温度是200 °C，但短时间的更高温度暴露也几乎不会引起损伤。

Polytetrafluoroethylene (PTFE) is a fluoropolymer which is the most lubricious polymer with low co-efficient of friction. PTFE tubing is chosen due to its excellent hydrophobicity, chemical inertness, and ability to withstand high pressures. It is suitable for protecting the optical fibres.

PTFE tubing may be used to connect the gas lines to the ports during Gas Chromatography-mass spectrometry analysis of volatile organic compounds from potato tubers inoculated with Phytophthora infestans or Fusarium coeruleum.
