Our vent plugs feature a microporous ePTFE membrane for reliable pressure equalization and moisture blocking.
Designed with standard metric and PG threads for quick, dependable fitting into any enclosure.
The Science Behind the Seal
How Our Breathable Vents Work
The core of our vent plug is a microporous ePTFE membrane. Its unique structure contains millions of tiny pores, large enough to allow air and vapor molecules to pass through freely, but thousands of times smaller than a water droplet. This enables continuous pressure equalization while providing an impenetrable barrier against liquids and particulates.
Avoids stress on enclosure seals and gaskets caused by internal and external temperature fluctuations.
Allows humid air to escape before it can cool and condense into damaging moisture inside the enclosure.
By maintaining a dry, stable internal environment, our vents significantly prolong the life of sensitive electronics.

Frequently Asked Questions
A breathable vent plug’s main purpose is to equalize the pressure between the inside and outside of a sealed enclosure. It allows air to pass through a microporous membrane, preventing pressure buildup from temperature changes, while blocking water, dust, and other contaminants from entering. This prevents condensation and protects sensitive internal components.
You should match the thread size of the plug or vent to the size of the unused entry hole in your enclosure. Our accessories are available in standard Metric (M) and PG thread sizes. Please refer to the specifications of your enclosure or measure the diameter of the entry hole to ensure a correct fit.
Our standard screw plugs and breathable vent plugs are all certified to an IP68 protection level. This means they are fully protected against dust ingress and can withstand continuous immersion in water under specified conditions, providing the highest level of reliability for your enclosures.
