AV - Adapter Plug, 8mm - Highly Recommended
This is a plug to keep esa-systems adapters free from insects and dust when the probe is removed. It has a small vent port to avoid creating pressure in the system when the plug is inserted and removed - which could damage the flight instruments. It also comes with a "Remove Before Flight" flag and a ring to connect the flag to the plug.

Caution: Using cloned (copied) plugs without a vent port can cause damage to the flight instruments.


  • Works with UN, SUN and ST mounting adapters or any 8 mm port


Plug Material: anodized aluminum
Flag Material: fabric

Diameter of the part that fits into the mounting adapter: 8 mm (0.315 inches)
