Automotive Electronic Enclosure Vents
Without the fragility and variability common in non-sintered materials, POREX Virtek® PTFE, which is specifically designed for automotive venting applications, uses unique sintered material that outperforms other material options. With its robust porous structure, our vents utilize an air-permeable structure that equalizes pressure and protects the enclosure seals from premature failure.
