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. Our moly rings resist scuffing, reduce drag and seat fast.

Chrome-plated top compression rings, engineered for harsh-condition use, handle the heat, friction, abrasion and corrosion problems encountered in high-load engines. Sealed Power’s chrome-plated top rings are pre-seated at the factory, delivering instant sealing when the engine starts.
