Cometic C4493-120 Peugeot MLS Cylinder Head Gasket Bore - TU5 J4 79mm

The Cometic C4493-120 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Peugeot TU5 J4 engines. This precision gasket features a 79mm bore diameter and .120" (3.0mm) compressed thickness, designed to deliver superior sealing performance under demanding conditions.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum durability and reliability
• 79mm bore diameter for precise fitment on TU5 J4 engines
• .120" compressed thickness for optimal compression ratio tuning
• Advanced embossment technology ensures consistent clamping force
• Superior resistance to combustion pressure and thermal cycling
• Eliminates gasket failure from high cylinder pressures and temperature extremes

Cometic MLS gaskets feature multiple layers of stainless steel with proprietary coatings that provide exceptional conformability to sealing surfaces. The embossed layers create additional sealing stress points around combustion chambers, coolant passages, and oil ports. This design makes them ideal for both performance builds and demanding OEM replacement applications where reliability is critical.
