Automotive Lights
Without the fragility and variability common in non-sintered materials, POREX Virtek® PTFE, which is specifically designed for exterior automotive lights, uses unique sintered material that outperforms competitive expanded materials. With its robust porous structure, our vents equalize pressure while minimizing humidity flow into the enclosure, protecting enclosure seals from premature failure.
