Head gaskets range expanded for commercial diesel engines

Federal-Mogul Motorparts recently announced the expansion of the FP Diesel ML7 multi-layer core head gaskets range, which now includes popular commercial diesel engines used in mining, construction and other demanding applications.

ML7 head gaskets are engineered and manufactured to withstand significantly higher combustion pressures and temperatures, and to accommodate increased vertical and lateral motion between the engine block and cylinder head.

Now available for Caterpillar C15, Cummins ISL, QSL, ISX, QSX and M11, and Detroit Diesel 50 and 60 Series engines, FP Diesel ML7 head gaskets incorporate three solid steel cores sandwiched within an advanced graphite composite material.

The multiple layers are tied together through precisely engineered perforations in the graphite material and an intermediate, secondary sealing layer. Each gasket’s steel core reinforcement helps ensure optimal compressed thickness for improved combustion, better fluid sealing capabilities and superior heat-resistance for high output engines.

Federal-Mogul Motorparts’ engineers designed each gasket to achieve optimal load balance between all component materials, including the gasket body and combustion armour.

The wire used in the combustion armour is manufactured from a copper flash-coated, low-carbon steel that better absorbs stress without cracking, compared to commonly used stainless steel wire.

Each gasket also features a proprietary moly coating to address the conformability demands of the variety of surface finishes found in the engine rebuild service environment. This coating helps seal imperfections in the head and block mating surfaces and allows the gasket to adapt to controlled casting motion. It also ensures a no-stick release for future engine work.

“A gasket’s ability to accommodate rising pressures and temperatures, as well as increased casting motion, has become increasingly important as original equipment manufacturers (OEMs) reduce overall engine mass and boost cylinder efficiency,” says Frank Piojda, Director, Off-Highway/ Heavy Duty: EMEA, Federal-Mogul Motorparts.

“Commercial engine rebuilders look to Federal-Mogul Motorparts and the FP Diesel brand for the latest and best engine sealing solutions. The ML7 design helps our customers maximise engine durability and productivity in an age when their equipment is being operated in extremely harsh conditions.”
