Reliable Auto Venting Solutions for Water-proofing EV & ICE Electronics

Gore‘s auto venting products block ingress of rain, sleet, snow, dust, dirt and debris, protecting electronic components in extreme environments. They continuously respond to pressure differentials, quickly equalizing over-pressures and vacuums, which protects the integrity and longevity of seals for life-of-vehicle performance.

Why Gore
Gore is ready, with life-of-vehicle automotive venting performance for today’s auto market. GORE® Automotive Vents protect electronic components from damage, degradation, or premature failure in harsh environments.

Waterproof and Breathable
Gore’s proprietary microporous membrane allows air and gases to pass through freely, equalizing pressure and diffusing moisture.

Moisture Diffusion
Our vents effectively diffuse moisture to help avert condensation challenges.

Rapid Pressure Equalization
GORE® Vents rapidly and continuously equalize over-pressures and vacuums created by environmental changes, whether the vehicle is moving or parked.

Durable Protection
GORE Vents safeguard electronic components from damage and help ensure long-term reliability by consistently blocking water, automotive fluids, and particulates from entering housing.

Whether it’s an Internal Combustion Engine, Hybrid, or EV, all our vents are extensively tested and evaluated in both laboratory and field conditions, to ensure they will perform consistently and reliably.

New Options Technical Cleanliness

In addition to our traditional GORE® PolyVents, we offer a new high-performance option that meets the most rigorous industry standards and OEM requirements: our “Cleanliness Protected” (CP) option.

“Cleanliness Protected” GORE PolyVents (Screw-In and Snap-Fit) 

These “CP” vents are independently certified for cleanliness that aligns with ISO 16232 and VDA 19.1 standards. This new level of part cleanliness minimizes the risk of contaminant-induced issues — like current leakage, short circuits or voltage flashovers  — that could create field failures in EV high-voltage components or ADAS sensors.

Technical Specifications

Screw-In Vents and Snap-Fit Vents:  

Mechanically rugged and easy to integrate.

Screw-In Vents

  • Standard Series: Withstands typical automotive fluids and continuous temperatures up to 125°C.
  • High-Airflow Series: Has 8x the typical airflow of our Standard Series, for very large components/electric motors/batteries for hybrids.

Snap-Fit Vents

  • Standard Series: Withstands typical automotive fluids and continuous temperatures up to 125°C.
  • High Temperature Series: For long-lasting resistance to chemicals and mineral oils even after extended exposure to temperatures up to 150°C.
  • High Airflow Series: Has 5x the typical airflow of our Standard Series, for very large components, electric motors, or for EV/Hybrid battery box venting.
  • Compact Series: Robust protection in a low profile design, for extremely small components. Scannable Digital Matrix Code (DMC) for 100% airflow check and enhanced traceability.

Small, lightweight vents install easily, bond securely and have high chemical roll-off performance, to maintain airflow.

  • High Durability Series: These all-membrane vents provide our highest level of protection and durability in the harshest conditions. Designed to perform reliably in either outside-mount or inside-mount applications. A range of sizes, for small to medium enclosures.
  • High-Airflow Series: These laminate vents provide our highest airflow, for faster pressure equalization. Designed for inside mounting only. A choice of sizes, for small to medium enclosures.

Save space, install easily and securely, and provide lasting protection for sensitive electronics.

  • High Airflow Series: Uses a multi-layer laminate construction to deliver our highest airflow and good chemical resistance. For use in typical operating temperatures from -40 °C to 150 °C. Available as cut disks in bags.
  • High Temperature Series: Offers our highest temperature- and chemical-resistance, in our thinnest format. The 100% ePTFE construction withstands operating temperatures from -40 °C to 160 °C. Available as cut disks on rolls.
