Gore icon for seal integrity

A sealed lamp enclosure protects everything within it from environmental challenges and contaminants. But what protects your seals from stress due to over-pressures or vacuums forming inside the enclosure?

GORE® Automotive Vents help to maintain seal integrity over time, because they rapidly and responsively equalize pressure differentials between the lamp interior and the outside world. Our membrane vents rapidly shed automotive fluids, soaps and other washing materials after contact, so they continue to equalize pressures. That prevents pressure-induced stress which could cause seals to fail prematurely, exposing lamp components to damaging environmental contaminants.

Bi-directional airflow resolves pressure imbalances whether vehicle is moving or parked.

How it works

Our vents' membrane of 100% ePTFE (expanded polytetrafluoroethylene) allows air and gases to pass through in both directions, rapidly bringing interior and exterior pressure differences into equilibrium.  This process is ongoing, so these pressure imbalances are resolved whether the vehicle is moving or parked.
