HKS 1.2mm Bead Type Head Gasket for Toyota Supra / 7M-GTE

BEAD TYPE HEAD GASKET

A bead is a type of spring used to maintain surface pressure which is very well suited to head gasket use. The beads are laid out to provide optimum pressure and seal around the combustion chamber. By carefully designing and adjusting the bead shape and heights, precise control of surface pressure is achieved for optimum results. Using a combination of 3 different types of beads allows maximum efficiency and performance.
