Porex Hydrophobic & Oleophobic PTFE Cap Vents 


Particulate and moisture contamination are persistent challenges faced by automobile manufacturers, as they can lead to detrimental effects on the fluid systems of vehicles. Rust, viscosity changes, sludge formation, and other issues can compromise the performance and reliability of automotive components. To address this critical concern, Porex offers a range of innovative solutions specifically designed to protect fluid reservoirs from the ingress of moisture and contaminants.

At the core of Porex’s offering is the highly customizable and self-supporting Virtek PTFE filter media. This advanced filtration material is engineered to be extremely hydrophobic, effectively repelling moisture and preventing its entry into fluid systems. Additionally, the high-temperature resistance of Virtek PTFE ensures reliable performance even under demanding conditions, safeguarding the integrity and functionality of automotive fluid reservoirs.
