3/4 in NPT Grey Liquid Tight Threaded Vent Plug | 21.8mm Length | Nylon 66
A practical choice for membrane protected venting, this grey protected airflow plug is manufactured from Nylon 66 to fit a 3/4 in NPT thread with 32.8mm across flats and 21.8mm overall length. It is designed for enclosures, housings and threaded ports where internal air movement must be managed without leaving the opening unfinished.
The thread form provides a positive mechanical fixing compared with push-in ventilation plugs. This is useful for applications where vibration, movement or weather exposure may affect ordinary closures. The grey finish can also support visual identification on hydraulic equipment covers, 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.
