Ergal third generation cylinder head with large sealing ring (TC03E).
The large sealing ring ensures perfect watertight integrity on all cylinders on the market,
managing to adapt perfectly to both large and small holes.
This cylinder head is equipped with an innovative stop in a new technological material: the VULKOLLAN.
The technical characteristics of this elastomer consist of:

- high resistance to dynamic stresses
