MS® PTFE Venting Membrane Applied in Pressure Sensors

Letting your sensors breathe more easily



Pressure sensors face the rigors during use and they must survive weather extremes from ice to rain to heat waves, and road hazards from puddles to grit, oils and mud. Membrane Solutions’ Vents provide superior protection, effectively repelling water, oils and particulates. Our performance-proven vents reliably protect sensitive sensors from water and harsh road contaminants, for the long haul.


  • rapidly equalize pressure differentials / continuously diffuse internal moisture
  • resist thermal shock / withstand temperature fluctuations from -40°C up to +150°C
  • enhance durability / reduce stress on seals, connectors and housings
  • Waterproof and dust proof / to ensure the properties of pressure sensor,and keep the reliability
