Clear Lenses for the Life of the Vehicle
Eliminate Lamp Fogging and Moisture Damage — IP6K/IPX9K Protected
Gore adhesive vents for automotive headlamps, rear lamps, fog lamps, and LED assemblies continuously diffuse moisture and equalize pressure — preventing lens fogging and seal failure whether the vehicle is moving or parked.

Lens fogging in automotive lighting is not just an aesthetic issue — it degrades light output, triggers warranty claims, and in LED assemblies, can accelerate LED degradation from thermal cycling in the presence of moisture. The root cause is straightforward: sealed lamp housings experience temperature and pressure changes that draw moist air in past gaskets and seals if there is no compliant pressure equalization path. Gore's adhesive lighting vents provide that path with a UV-stable ePTFE membrane that is waterproof, dustproof, and breathable. The membrane continuously diffuses moisture out of the lamp housing — whether the vehicle is parked overnight or driving at highway speed — and prevents the pressure differentials that stress seals. Products are rated to IP6K (full dust exclusion), IPX7 (immersion), and up to IPX6K/IPX9K (high-pressure spray) depending on the model selected. IATF16949-certified manufacturing and EU REACH compliance are standard.
Why Choose Gore Exterior Lighting Vents?
Continuous Moisture Diffusion — Parked or Moving
Unlike one-way check valves that only open under positive pressure, Gore's breathable ePTFE membrane is always active. Moisture vapor diffuses outward through the membrane continuously, even when the vehicle is parked overnight. This prevents the gradual moisture accumulation that eventually results in visible condensation on the inside of the lens.
IP6K/IPX7/IPX9K Ingress Protection
Full dust exclusion (IP6K), immersion protection to 1 meter (IPX7), and high-pressure spray resistance (up to IPX9K depending on model) ensure that the vent path itself does not become a weakness in the lamp's IP rating. Gore's proprietary membrane materials and IATF16949 manufacturing process deliver consistent IP compliance across production volumes.
Higher Moisture Vapor Transmission Than Competing Solutions
Gore's AVS 120 delivers 14% greater moisture vapor transmission rate (MVTR) than the industry-reference AVS 9 with identical outer dimensions. The AVS 113 variant showed 25–28% faster condensation clearing in comparative testing. Higher MVTR translates directly to fewer warranty claims and faster lamp recovery after temperature cycling.
UV-Stable ePTFE Membrane
Automotive exterior lighting is exposed to direct sunlight throughout the vehicle's service life. Gore's ePTFE membrane is intrinsically UV-stable — it does not degrade, discolor, or lose water-repellency under prolonged UV exposure. This is critical for forward-facing assemblies where competing hydrophobic surface treatments can degrade over time.
Smallest-Footprint Options for Compact LED Assemblies
Modern LED headlamp and tail lamp designs are often constrained by the optical and thermal management packaging, leaving minimal space for accessory components. The AVS 118/119 series offers the smallest footprint in Gore's automotive lighting vent range while maintaining full IP protection and moisture diffusion performance.
Seal Pressure Relief — Extends Gasket Life
Without pressure equalization, each thermal cycle forces the lamp housing seal to flex against internal/external pressure differentials. Over thousands of cycles, this degrades the seal and eventually allows bulk water ingress. Gore vents eliminate this pressure load on the seal, extending gasket and seal service life and reducing the leak failure rate over the vehicle lifetime.

Frequently Asked Questions
Does the Gore lighting vent affect the IP rating of my lamp housing?
Gore lighting vents are tested and rated to IP6K (dust), IPX7 (immersion), and up to IPX9K (high-pressure spray) depending on the model. The vent is designed to preserve or enhance the lamp's overall IP rating — not reduce it. Gore provides IP test data for each model to support your lamp-level IP qualification testing.
Which model is right for a compact LED DRL with very limited space?
The AVS 118 and AVS 119 series offer the smallest footprint in Gore's lighting vent range and are designed specifically for space-constrained accessory and fog lamp applications. For headlamp modules where space is slightly less constrained, the AVS 120 provides the highest MVTR in the range. Contact RSTECH Electronics with your available footprint dimensions for a specific recommendation.
Can Gore lighting vents be applied in automated assembly processes?
All Gore adhesive lighting vents are available in reel formats compatible with automated pick-and-place and tape-and-reel assembly processes. Manual application formats are also available for lower-volume or prototype builds. Specify your production process when ordering through RSTECH Electronics.
Will the membrane saturate or lose effectiveness over time in a high-humidity climate?
Gore's ePTFE membrane does not saturate. It is hydrophobic — water cannot be absorbed into or retained within the membrane structure. Moisture vapor passes through the membrane by diffusion, not by liquid absorption, so the membrane's performance is unaffected by prolonged exposure to humid environments or repeated wetting.
