PTFE Vents


PTFE vents provide good temperature and chemical resistance. They’re made of polytetrafluoroethylene (PTFE), a synthetic fluoropolymer with strong support for low initial pressure drops. PTFE vents are also resistant to high surface tension, and are hydrophobic.*

Learn about the advantages and uses for PTFE vents, and how our custom vent manufacturing can meet your PTFE venting requirements.

Interstate Specialty Products die-cuts PTFE vents for medical and scientific, electronics, and industrial applications. For over 50 years, our Made in the USA manufacturing company has been die-cutting non-metal materials at our custom fabrication facility in Sutton, Massachusetts.

Applications for PTFE Venting

In the automotive industry, PTFE venting is used in fuel tanks, gas caps, electronic control units, and lighting assemblies. With their high permeability and mechanical strength, PTFE venting membranes are also a good choice for electric window motors, windshield wiper motors, and air conditioning pressure sensors.

Additional applications for PTFE vents include portable electronic devices, electronics enclosures, and MEMS and transducer protection. With their high water intrusion pressure and resistance to salt water and UV light, PTFE vents are also ideal for marine enclosures.

In the food and beverage industry, PTFE packaging vents provide moisture protection and can meet food contact requirements. Other applications for PTFE venting membranes include cap, lid, and thermal vents.
