FEATURE / SPEC
■ SUPER GROMMET DESIGN
The sealing performance has been improved considerably with the super grommet,to suit these engines and has been proven to brliver excellent relibility.
SUPER GROMMET TYPE The dual sealing method of the bead structure & metal grommet, provides maximum sealing for the coolant, oil & gases around the bore circumference. |
■ Durable stainless steel made
The bead top pry is made of durable but flexible SUS301.
High heat radiation character of SUS301 helps transferring heat of the head and the block to coolant efficiently and prevents heat spots which causes gasket blow.
SUS301 is also known for its tensile strength and it helps the beads to keep sealing the head and cylinder which repeat heat expansion and shrink all the time. This structural strength also improves torsional rigidity of the whole engine by improving coupling rigidity of the head and the block.
■ ABOUT MARKING
All our metal head gaskets are laser marked with Models, Bores, Thickness, and TOMEI POWERED INC. company name. Since there are similar/counterfeit goods on market, please make sure logos on Gasket. |
