Federal Mogul Fel-Pro HS 26415 PT-1 PermaTorque MLS Engine Cylinder Head Gasket Set

The Fel-Pro HS 26415 PT-1 is a PermaTorque Multi-Layer Steel (MLS) Engine Cylinder Head Gasket Set engineered by Federal Mogul for demanding real-world repair environments. This head gasket set is purpose-built to deliver a reliable, leak-free seal even on imperfect or worn sealing surfaces, making it a trusted choice among professional technicians and engine builders alike.

Key Features:

• Multi-Layer Steel (MLS) Construction: Multiple layers of stainless steel maintain consistent sealing stress and accommodate head lift common in late-model engines
• LaserWeld Technology: A laser-welded stopper layer reduces head lift and ensures a stronger, more consistent combustion seal
• Proprietary Coating: Exclusive surface coating withstands rougher sealing surface finishes up to 80 Ra, helping seal imperfect mating surfaces
• Superior Combustion Seal: Precisely embossed sealing beads at all critical areas eliminate potential leak paths under high cylinder pressures
• Application-Specific Design: Engineered and validated specifically for the repair environment — validated for fit, form, and function
• OEM-Level Quality: Built to meet or exceed all original equipment specifications

The head gasket is one of the most critical seals in any engine, responsible for maintaining maximum compression while preventing coolant and engine oil from entering the cylinders. The Fel-Pro HS 26415 PT-1 withstands the constant stresses of thermal expansion, contraction, surface warping, and dynamic head movement to provide a lasting seal.
