It provides a tight seal around the objective lens assembly, protecting the optics and electronics from dust, moisture, and contaminants.

Compatibility

The seal is designed for the objective lens assembly of PVS-7 night vision goggles. Replacement should be considered whenever the objective lens is removed, as well as when the old seal is cracked, flattened, or has lost its flexibility – at that point, it no longer effectively protects the inside of the device from moisture. A separate O-ring is used to seal the goggles housing. It is recommended to verify the part number in the service documentation of your specific unit before ordering.
