Benefits

Additional features ensure safe sealing to atmosphere:
- Risk of leakage is reduced by internally mounted hinge pin. The hinge pin mounting bracket is welded directly to the inside of the cover, so no additional seal to atmosphere is required.
- Serrated cover gasket, fully confined to prevent creep.
