    great vent plug
    I installed this brass air vent plug on my electric vehicle's battery enclosure and it works perfectly. The IP67 rating provides excellent protection while still allowing necessary ventilation. This brass air vent plug has held up really well against moisture and temperature changes. It's exactly what I needed for maintaining proper airflow without compromising safety.
