How It Works

The Plastic Vent Valve utilizes a microporous PTFE or ePTFE membrane embedded into a durable plastic housing. When environmental temperature changes cause pressure differences inside the device, the membrane allows air to flow in and out while blocking liquid and dust particles. This pressure equalization prevents internal condensation, casing deformation, and performance degradation.

Our advanced production techniques ensure the perfect balance between breathability and protection – making Waterproof Plastic Vent Valves essential for sealed enclosures exposed to outdoor conditions.
