Hoonsun Metal vent plug is designed to provide reliable airflow/pressure equalization while preventing ingress of liquid, dust and contaminants into sealed enclosures. Ideal for applications such as outdoor lighting housings, electronics enclosures, industrial equipment, transportation systems, and any environment where internal pressure must be relieved without compromising the sealed integrity.
Key Features:
Allows gas/air to pass while blocking water, moisture, dust and solids.
Helps prevent condensation build-up inside sealed equipment by enabling pressure equalization during temperature/humidity changes.
Constructed with durable metal body (e.g., brass with nickel plating, stainless steel, aluminum alloy) for high strength, corrosion resistance and long life.
Incorporates a breathable membrane (for example ePTFE or sintered metal) with microporous structure, providing good air flow while maintaining protection against liquid ingress.
High protection rating available (for example IP67/IP68) suitable for outdoor or harsh industrial environments.
Threaded or screw-in design for easy installation into housing or enclosure panels (common thread sizes: M3–M20, or other metric/imperial).
Excellent chemical, temperature and mechanical performance: many models operate from around -40 °C to +125 °C (or higher depending on material), and resist harsh environments.
Applications:
Enclosures for outdoor lighting, LED fixtures, street lamps, floodlights.
Automotive/transportation housings and sealed modules.
Industrial equipment and control panels where internal condensation needs to be prevented.
Electronic devices, communication equipment, instrumentation in harsh/dusty/wet conditions.
Marine, outdoor, extreme-temperature environments requiring ventilation with protection.
