Federal Mogul HS 26534 PT Fel-Pro PermaTorque MLS Cylinder Head Gasket Set

The Federal Mogul / Fel-Pro HS 26534 PT is a premium cylinder head gasket set engineered specifically for the repair environment. Built under the trusted Fel-Pro brand — a division of Federal-Mogul Motorparts — this head gasket set delivers the application-specific sealing performance that professional technicians rely on.

At the heart of this set is Fel-Pro's PermaTorque® MLS (Multi-Layer Steel) technology with LaserWeld™ Stopper Layer, which uses multiple layers of full-hard stainless steel combined with strategically placed sealing beads to maintain consistent contact pressure between the cylinder head and engine block. The LaserWeld™ Stopper Layer limits compression at the combustion opening, helping prevent gasket blowout and ensuring a superior combustion seal.

Key Features:

• PermaTorque® MLS construction with multiple layers of full-hard stainless steel
• LaserWeld™ Stopper Layer technology for superior combustion seal integrity
• Exclusive proprietary polymer coatings to accommodate imperfect sealing surfaces and higher engine temperatures
• NextGen coating compensates for surface finishes as rough as 80 Ra
• Strategically located sealing beads surround combustion chambers and coolant passages to concentrate clamp load in critical areas
• Application-specific engineering validated through on-vehicle testing
• Set includes all parts needed for a complete head gasket repair

As one of the most critical components in any engine repair, the head gasket seals the cylinders to maintain maximum compression and prevent coolant or engine oil from entering the combustion chamber. The Fel-Pro HS 26534 PT is engineered to withstand the stresses of thermal expansion, surface movement, and high combustion pressures — delivering a long-term, leak-proof seal professionals trust.
