1/2in NPT Grey Liquid Tight Threaded Vent Plug | 20.6mm Length | Nylon 66
Used where airflow is needed without liquid ingress, this grey liquid tight ventilation plug is manufactured from Nylon 66 to fit a 1/2in NPT thread with 24.9mm across flats and 20.6mm overall length. It is designed for enclosures, housings and threaded ports where internal air movement must be managed without leaving the opening unfinished.
This plug is made for demanding enclosure work where simple hole coverage is not enough. It supports airflow management while helping maintain protection in damp or dusty surroundings. The grey finish can also support visual identification on pneumatic control assemblies, 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
- Battery box ventilation
- Automation sensor enclosures
- Fabricated box sections
