Federal-Mogul's Sealed Power® brand offers premium molybdenum-faced and chrome-plated compression rings that are lapped to a light-tight finish for fast break-in and positive blow-by control. These materials are the ideal choices for top rings, which get the most heat, the most pressure and the least lubrication.

Rings made with molybdenum (moly), a hard, low-friction metal, have outstanding oil-carrying capacity to provide excellent top-ring lubrication. Federal-Mogul's Sealed Power® brand moly rings resist scuffing, reduce drag and seat fast.
