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.

Frequently Asked Questions
Threaded Vent Plugs are designed to equalise pressure and provide controlled airflow within sealed enclosures whilst helping prevent the ingress of dust, moisture and contaminants. They are commonly used to protect sensitive electrical and electronic equipment from condensation and pressure build-up.
Threaded Vent Plugs allow air to pass through a specialised vent membrane whilst blocking water, dust and other contaminants. This helps maintain a stable internal environment and reduces pressure changes caused by temperature fluctuations.
Most Threaded Vent Plugs are manufactured from durable, flame-retardant UL94V-2 rated Nylon 6/6, providing excellent strength, corrosion resistance and long-term performance in industrial environments.
Many Threaded Vent Plugs are available with IP68 ingress protection, allowing pressure equalisation whilst preventing water, dust and other contaminants from entering the enclosure.
Threaded Vent Plugs help prevent pressure build-up and condensation inside sealed enclosures. This protects sensitive electrical components, extends equipment life and improves the reliability of systems operating in changing environmental conditions.
Yes. By allowing controlled airflow and pressure equalisation, Threaded Vent Plugs help minimise condensation inside enclosures caused by rapid temperature changes and humidity.
