What Is Waterproof Breathable Valve？

A Waterproof Breathable Valve is an essential component used in various electronic, automotive, and industrial systems to maintain pressure balance and prevent moisture intrusion. Designed to offer both waterproofing and air permeability, these valves ensure stable internal environments, prolonging the lifespan and performance of sensitive components.

Our Plastic Breather Valves and Venting Solutions are engineered with advanced materials and precision manufacturing, providing optimal protection in harsh environments. Whether used in battery packs, lighting systems, outdoor enclosures, or automotive components, they deliver exceptional reliability, ensuring that air flows freely while liquids, dust, and contaminants are kept out.

The Waterproof Plastic Vent Valve combines robust sealing performance with effective pressure equalization. Constructed using high-quality engineering plastics or aluminum alloys, these valves feature IP67-level waterproof protection, ensuring that devices remain safe even when exposed to rain, splashes, or temporary immersion.

Each Plastic Breather Vent is designed to allow airflow through a Waterproof And Breathable Membrane, enabling gas exchange without compromising protection. This prevents condensation buildup inside sealed devices — a critical factor in maintaining electronic performance and preventing corrosion.

Key Features

• Waterproof and Breathable Design – Provides IP67 protection while maintaining airflow to stabilize internal pressure.

• Corrosion-Resistant Construction – Made with durable plastic or aluminum materials resistant to chemicals, salt spray, and environmental wear.

• Pressure Equalization – Prevents deformation or leakage caused by temperature and pressure changes in sealed systems.

• High Durability – Designed to withstand extreme temperatures and outdoor conditions for long-term use.

• Compact and Customizable – Available in multiple sizes, materials, and configurations to match specific product requirements.
