Waterproof vent plugs are essential device for improve the protection of equipment benefit thoroughly, especially in applications where it is required to prevent the ingress of moisture (water vapor), dust or other contaminants through the internal volume of a device while allowing gas exchange to minimize pressure differential across a barrier. These vent plugs are commonly incorporated in outdoor applications including LED lighting, automotive components, sensors, ECUs (electronic control units), telecommunication equipment as well as solar enabled systems. They safeguard the equipment from extreme environment without affecting normal operation and prolong its life cycle.

Depending on configuration, pore size, air flow rate, adhesion level and material, custom vent plugs can be tailored for a wide range of venting applications. With these custom solutions, waterproof vent plugs can address the requirements of different industries and deliver efficient, reliable eco-friendly waterproof breathable protection. Waterproof vent cap/vent plug, vent with high permeability and protection classification can eliminate the fog quickly in the headlights to avoid sagging! Besides, a variety of protection levels are offered–IP54/IP67/IP68/IP69K.
