HEAD GASKET

The head gasket is a vital component within the combustible engine. The head gasket ensures the pressure created from the spark plug’s ignition of fuel vapors remain within the combustion chamber. The combustion chamber contains the pistons and needs a high amount of pressure to ensure the pistons continue to fire appropriately.

INLET GASKET

Inlet gaskets are made of rubber or non-asbestos, which helps eliminate the possibility of leakage. An inlet gasket is a flexible, fitted part of a car engine that helps prevent air from leaking out during fuel combustion and helps regulate chamber temperature.

Muti-layer steal

MLS Gasket features an extra fold-over layer providing a torque limiting surface that prevents yielding of the combustion seals. MLS gaskets have several layers of thin carbon steel that are embossed and crimped in the critical sealing area. This type of gasket is capable of sealing at higher pressures than older composite gaskets.
