Controlled Vapor Exchange for Drums and Specialty Containers
Stop Container Bulging and Collapse — Without Risking Liquid Leakage
Gore plug-in ePTFE packaging vents install directly into standard bung ports on drums, IBCs, and specialty containers, providing controlled vapor exchange and pressure equalization while maintaining a complete barrier against liquid egress — even with high-viscosity or low-surface-tension contents.
Plug-in ePTFE membrane vents for drums, containers, and specialty packaging requiring controlled vapor exchange and protection against liquid ingress. Gore plug-in vents thread or push into standard bung openings on UN-rated drums, intermediate bulk containers (IBCs), and custom packaging. The ePTFE membrane allows oxygen, nitrogen, and vapor to exchange with the atmosphere — preventing container deformation from temperature changes, altitude, and outgassing — while its hydrophobic and oleophobic surface properties block liquid contents even after contact with high-viscosity or low-surface-tension fluids that block conventional vent membranes. Validated to DOT and ADR transport regulations for hazardous goods packaging.
Why Choose Gore Plug-In Packaging Vents?
Prevents Container Deformation in Transport and Storage
Temperature changes during transport (from warm warehouse to cold transport, or vice versa) and altitude changes in air freight cause significant pressure differentials inside sealed containers. Gore plug-in vents equalize this pressure continuously, preventing the drum bulging, IBC panel distortion, and closure failure that results in dangerous leaks and costly product loss — without requiring manual pressure relief operations.
Repellency Maintained After Liquid Exposure
Many vent membranes lose their liquid repellency after contact with low-surface-tension fluids such as solvents, detergents, and agricultural concentrates. Gore ePTFE membranes are intrinsically oleophobic and hydrophobic — their surface repellency recovers rapidly after liquid contact, maintaining consistent airflow and liquid containment throughout the container service life. This is a critical differentiator for agrochemical and institutional cleaner packaging.
DOT and ADR Compliant for Hazardous Goods
Gore plug-in packaging vents are validated in DOT (US Department of Transportation) and ADR (European Agreement for Dangerous Goods by Road) test programs for packaging hazardous substances. This validation supports the use of vented packaging in regulated transport scenarios without requiring individual shipper testing — reducing compliance cost for chemical, pharmaceutical, and agrochemical manufacturers.

Frequently Asked Questions
What bung sizes are compatible with Gore plug-in packaging vents?
Gore plug-in vents are designed for standard UN drum bung sizes including 2-inch (51 mm) and 3/4-inch (19 mm) openings commonly found on UN-rated steel and plastic drums. IBC bung compatibility depends on the IBC closure standard. Contact RSTECH Electronics to confirm compatibility with your specific container bung specification.
How does the vent maintain repellency after contact with low-surface-tension fluids?
ePTFE is inherently both hydrophobic and oleophobic. When a low-surface-tension liquid contacts the membrane surface, surface tension forces prevent the liquid from penetrating the pore structure. After liquid drains from the surface, the membrane regains its full gas permeability. This recovery behavior is measured and reported by Gore and distinguishes ePTFE from surface-treated membranes that lose repellency after liquid contact.
Can Gore plug-in vents be used for air freight of hazardous goods?
Pressure changes in aircraft cargo holds (typically 0.55–0.75 bar cabin pressure equivalent) place significant stress on sealed containers. Gore plug-in vents equalize this pressure and prevent closure failure during air freight. Specific air transport regulations (IATA DGR) requirements should be verified for each product classification — contact RSTECH for regulatory compliance support.
