INTERNAL SEALING WASHER

Ensures gas tightness of the spark plug

1) Transmits heat from the insulator tip to the shell
2) Prevents leak of gases from the combustion chamber into the spark plug
3) Compensates and distributes the tension from pres-tress during electrothermal assembly

BRISK TIP

BRISK utilises its long-term experience with electro-thermal assembly technology and knowledge of thermal flows between the spark plug and engine parts.
