4. To check O-rings for damage, place the O-ring between the index finger and thumb.
Then pull the O-ring through your fingers, feeling for any debris or wear.
5. If O-rings are dirty, it is best to replace them. Washing dirty O-rings with soap and
water is not recommended. Soap breaks down the lubricants and will compromise
the integrity of the seal.
6. Properly greased O-rings will help maintain sealing integrity and minimize O-ring
degradation. Use enough grease to lubricate the O-ring thoroughly, but not so much
that it will attract additional debris.
7. Clean the groove with a lint free swab or the folded edge of a paper towel.
8. All of the front optic ports for the housing also utilize two O-ring seals. Also check
these seals every time the optic is removed.
