Threaded Vent Plugs

Threaded Vent Plugs — also known as ventilation plugs or pressure relief plugs — are essential components used to manage airflow and pressure inside sealed enclosures and housings. These are primarily used by professionals across industries such as electronics, manufacturing, automation, and electrical engineering, helping to prevent condensation, equalise pressure, and protect sensitive components.

Our comprehensive range includes both general-purpose and liquid-tight variants, suitable for applications with varying levels of exposure to dust, moisture, and other contaminants. Available in Metric, PG, and NPT threads — ranging from M12 to M20 and PG7 to PG21 — these plugs are offered in durable materials like UL94V-2 rated Nylon 6/6. Some models also feature built-in hydrophobic membranes, allowing airflow while blocking liquids and particles, with IP68 ingress protection ratings.

For non threaded applications, consider our Vent Plugs with the option for filtered and louvered styles.
