Fully fluorinated grease
Fully fluorinated grease (MOLYKOTE® HP-500 Grease) that is resistant to high temperature environments, exposure to chemicals and solvents, and deterioration.
Applying this grease to O-rings of waterproof dome covers and waterproof camera cases enhances the performance of O-rings and extends their service life.
How to apply grease
Apply a very small amount of fully fluorinated grease (just enough to stick to the fingertip) to the O-ring and blend it throughout.
