What are Liquid Tight Threaded Vent Plugs?

Liquid Tight Threaded Vent Plugs are durable components manufactured from UL94V-2 rated Nylon 6/6 and include an internally welded Acrylic Copolymer filter. This filter provides hydrophobic and oleophobic properties, helping to block water, oils, and contaminants while allowing airflow. Each plug features a built-in sealing washer that ensures IP65, IP67, and IP68 protection when correctly installed. With a hexagonal wrench head and compatibility with Metric, PG, and NPT threads, these plugs can be ...
