Fortified main pressure valve spring and silicon packing are used to raise the pressure inside the radiator for a higher boiling point. The coolant will not boil easily, prevents air bubbles in the block and radiator core with improved heat transfer.
PIVOT's high pressure radiator caps works at 1.3kg/cm2 at zero atmospheric pressure. In practice though, the atmospheric pressure of the road surface (approximately 1.0kg/cm2) is added and the pressure is 2.3kg/cm2.
In summary, Pivot Radiator Cap:
- Increases pressure of radiator up to 1.3 Bar.
- Improves radiator cooling.
Available in 2 models:
