Performance Head Gaskets
The LaserWeld™ stopper layer in Fel-Pro® Performance MLS head gaskets provides a precisely-determined limit to the compression of the multiple layers at the combustion opening. This vital function helps prevent gasket damage and ensures a superior combustion seal.
Fel-Pro® Performance MLS gaskets are composed of four to five stainless steel layers, along with proprietary coatings. Strategically-located sealing beads surround the combustion chamber and coolant passages, concentrating clamp load in the most critical areas.
PERFORMANCE WIRE RING
Fel-Pro® Performance wire ring head gaskets feature a 321 Series stainless steel armor surrounding each cylinder, in addition to a pre-flattened steel or copper wire ring that provides highly-concentrated sealing around the combustion chamber.
These gaskets use a rubber/fiber-facing material laminated to a solid steel core to resist torque loss and seal fluids.
