Our porous plastic Vent Plugs prevent sparks or fire from entering into a machine / device, while allowing free flow of air and other gases. Numerous devices, such as batteries, emit various gases during operations; these gases may be flammable (hydrogen, ammonia, methane, etc.). In the event that these flammable gases come in contact with a spark or flame, our porous plastic Vent Plugs prevent the fire from entering the battery, keeping it safe.

In addition, these porous plastic products also prevent the entry of unwanted solid and liquid particles into the battery which could compromise the functioning of the battery and negatively impact the operations of the automobile. Our Vent Plugs are designed to be chemically inert and physically strong, with a sturdy external casing, making them durable and ideal for long-term use situations.
