3/8 in NPT Black Liquid Tight Threaded Vent Plug | 17.5mm Length | Nylon 66
Specified for moisture-controlled ventilation, this black sealed enclosure vent plug is manufactured from Nylon 66 to fit a 3/8 in NPT thread with 21.0mm across flats and 17.5mm overall length. It is designed for enclosures, housings and threaded ports where internal air movement must be managed without leaving the opening unfinished.
The design helps sealed housings breathe as internal pressure changes, reducing stress on seals and enclosure walls. It is well suited to electrical cabinets, telecom boxes and outdoor equipment housings. The black finish can also support visual identification on machinery housings, helping maintenance teams quickly distinguish threaded ventilation points from plain blanking plugs.
What Are Liquid Tight Threaded Vent Plugs?
Liquid tight threaded vent plugs are threaded ventilation components used to equalise pressure inside enclosures while helping block liquid, dirt and particulate contamination. They are commonly used where sealed equipment needs to breathe without compromising protection around sensitive internal parts.
Common Applications
