MS27063F
MS27071, MS27072, and MS27087 parts shall be coated with the same type of dry film lubricant as indicated in the PIN, no mixing of dry film lubricants shall be used on an assembly unless it is of the types specified by the "blank" designator.
NOTE: Avoid using graphite dry film lubes with aluminum unions and nipples because in a wet environment, graphite becomes corrosive to the aluminum.
