Federal Mogul HS 26531 PT Fel-Pro PermaTorque MLS Cylinder Head Gasket Set

The Fel-Pro HS 26531 PT PermaTorque Engine Cylinder Head Gasket Set is engineered specifically for the real-world repair environment, delivering a dependable seal on even the most demanding applications. As a cylinder head gasket set built around Fel-Pro's proprietary PermaTorque MLS (Multi-Layer Steel) with LaserWeld technology, this set is validated on-vehicle to ensure optimal sealing performance and long-term durability.

The cylinder head gasket is one of the most critical components in your engine. It seals the cylinder bores to maintain maximum compression while preventing engine oil and coolant from mixing or leaking into the combustion chamber. Over time, thermal cycling causes cylinder heads to warp and pit, making a high-quality replacement gasket set essential for a reliable repair.

Key Features:

• PermaTorque MLS with LaserWeld Technology — Exclusive LaserWeld stopper layer reduces the risk of blow-out and delivers a stronger, more consistent combustion seal
• Multi-Layer Stainless Steel Construction — Multiple stainless steel layers maintain sealing stress and accommodate head lift under extreme engine conditions
• Proprietary Combustion Coating — Exclusive surface coating withstands rougher sealing surface finishes up to 80 Ra, helping seal imperfect or mildly worn mating surfaces
• Embossed Sealing Beads — Precisely placed embossed beads at all critical sealing areas eliminate potential leak paths for oil, coolant, and combustion gases
• Designed for Imperfect Surfaces — Engineered to compensate for surface imperfections and provide the proper amount of torque retention without requiring additional sealers
• Complete Gasket Set — Includes all gaskets needed for a full cylinder head reseal

Fel-Pro gasket sets are tested on-vehicle and validated to ensure proper fit and function straight out of the box. No additional sealers are required. Always inspect and resurface the engine block and cylinder head mating surfaces prior to installation to ensure they meet specification.
