GORE® Automotive Vents

Improving reliability while reducing design complexity

Each application has its own set of challenges, such as exposure to temperature changes, environmental conditions like water, dust, dirt and debris or even contact with automotive fluids including urea solutions, car wash fluids, and lubricants. Without the correct venting solution in place, these challenges can impact reliability and durability.

OEMs and Tier-1 suppliers worldwide turn to Gore for advanced automotive venting solutions for gas-powered, hybrid and electric vehicle applications. Our ePTFE vents rapidly equalize pressure variations caused by temperature changes while providing a reliable barrier to particulates, debris, water and automotive fluids. More reliable venting performance can reduce the need for heavier housings, seals and gaskets, so component design is less complex, manufacturing costs and time to market is reduced, and global cross-platform integration is simplified.

At Gore, we provide manufacturers with thorough partnership that includes finding the right solution to their challenges and testing our vents to ensure they meet or exceed industry standards and perform to specifications.

We can rapidly integrate a venting solution into your finished product or work with you to create a custom solution. By pairing our ePTFE venting expertise with unwavering standards for performance, we can help you to maintain the integrity of your products for the long term.


GORE® Packaging Vents

Allow Containers to Breathe Without Leaking

When containers filled with active formulations are not ventilated properly, serious consequence could occur — like bloated or collapsed containers, misaligned pallets, ruined labels and leaks, not to mention costly cleanups and dissatisfied customers.

Risks are even greater when containers are stored, transported or distributed, exposing them to a wide range of altitudes and temperatures that can destabilize pressure and even cause containers to burst. For industrial chemicals and cleaners, agricultural products and household chemicals and cleaners, leaks and ruptures could cause real harm to both users and the environment — unless the containers are properly vented.

Gore’s packaging vents minimize these risks by:

  • allowing air and gas molecules to pass through the membrane, continually equalizing pressure so containers won’t bulge or collapse
  • maintaining airflow even after contact with high-viscous or low surface-tension liquids
  • preventing leakage of dangerous and hazardous liquids

At Gore, we insist on failure-free performance. Our vents are subjected to extensive quality control tests, including thorough camera inspections, to ensure the vent is fit for its use. Additionally, we provide vents that meet the stringent ADR and DOT standards.

Unlike other suppliers, whose vents might clog the membrane or even leak, we provide proven solutions that optimize the safety and compliance of packaging.

The Technology Behind the Vents

What gives our packaging vents their superior performance qualities is expanded polytetrafluoroethylene (ePTFE), the remarkably versatile polymer at the heart of our products.

Gore is the world leader in understanding ePTFE and its capabilities. For each implementation, we use the GOREMembrane to engineer an ePTFE membrane structure with a variety of different properties tailored for both the liquid and its container.

Unlike competitors’ membranes, Gore's membranes are designed specifically for packaging venting applications where uncompromising leak protection and pressure equalization are critical. The GORE™ Membrane has excellent roll-off, so it easily “sheds” liquid and allows continuous airflow. Other membranes, while offering adequate initial airflow, experience poor roll-off when exposed to low surface tension liquids. Such liquids clings to and clog those membranes, reducing airflow and potentially causing serious damage.

This membrane has poor roll-off properties, enabling liquid to clog the membrane and reduce airflow.

The Gore membrane has excellent roll-off properties. Liquid easily drains off the membrane, allowing continuous airflow.

The ePTFE membranes in Gore’s packaging vents continually release gases while repelling liquid effectively. The result: containers that more reliably protect their contents during shipment and storage.
