Overview
Enclosures and containers are vulnerable. Vulnerable to failed seals, condensation and contamination. Vulnerable to leakage and structural failure.
How likely is an enclosure or container to fail? All it takes is a change in internal pressure that stresses seals. Even a change in temperature or altitude could cause a pressure change, or it could happen because the contents of a container outgas or scavenge oxygen. In the case of mobile devices, enclosures could fail if they’re inadequately protected against liquids, dust and other environmental factors. Whatever the cause, the result could damage a product’s performance and integrity, or even lead to an expensive product failure or significant clean-up.
GORE Vents keep the worst from happening. They allow enclosures and containers to breathe, equalizing pressure and reducing condensation while filtering out liquids and other contaminants. The result: greater product performance, increased durability, higher reliability and peace of mind.

Solutions Across Industries
Gore has paired our technological expertise - particularly in ePTFE, a highly durable and breathable material - with our understanding of venting requirements for automotive components, mobile devices, packaging, outdoor electronics and other devices.
Depending on the application, our vents can:
- equalize internal pressure to prevents leaks
- build a barrier to contaminants
- manage moisture and condensation
- preserve sound quality in acoustic components
- enable devices to survive in rugged environments
- contain challenging or hazardous chemicals in packaging
- enable fluid dispensing from a container, even hot fluids
We design each vent specifically for its application. Once the vent is built, we thoroughly test it in real-world conditions. As a result, vents are designed to perform to specifications - the first time and every time - and deliver outstanding service life.
Vulnerabilities can lead to product failures, customer dissatisfaction and worse. Manufacturers depend on Gore to deliver venting solutions so they, and their products, can breathe easy.

Optimizing Outdoor Electronics with GORE® Protective Vents
A recent field study confirms that GORE® Protective Vents are essential for maintaining the performance and durability of outdoor electronics. These vents ensure rapid pressure equalization, preventing seal damage caused by temperature fluctuations and protecting against water, dust, and other contaminants. An eight-year study in Putzbrunn, Germany, highlights their long-term effectiveness.

Automotive Vents
Improving reliability while reducing design complexity
![Red car and new Gore Automotive Vent AVS 120](/sites/default/files/2021-07/AUTO_Venting_Banner_1200x277.jpg 1x, /sites/default/files/2021-07/AUTO_Venting_Banner_1200x277.jpg 2x)
NEW GORE AUTOMOTIVE VENT AVS 120:
Enables faster clearing from the same part-size as AVS 9.
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 are reduced, and global cross-platform integration is simplified. Reliable acoustic venting can enhance the performance of noise-canceling systems, or driver-assistance systems that monitor important traffic sounds such as emergency vehicle sirens.
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.

Allow Containers to Breathe Without Leaking

![New Standard Series: A versatile solution for your “everyday” challenges](/sites/default/files/2017-04/Banner_1200x270_Standard_0.jpg 1x, /sites/default/files/2017-04/Banner_1200x270_Standard_0.jpg 2x)
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 GORE™ Membrane 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.](/sites/default/files/2016-06/BadRollOff_kleiner.jpg 1x, /sites/default/files/2016-06/BadRollOff_kleiner.jpg 2x)
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.](/sites/default/files/2016-06/Good-roll-off_V2_kleiner.jpg 1x, /sites/default/files/2016-06/Good-roll-off_V2_kleiner.jpg 2x)
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.
