High Pressure Valved-Radiator Cap

Regular price $35 Unit price  per 

Circuit Hero high pressure radiator cap uses a 1.3 kgf/cm² spring to increase your coolant/antifreeze boiling point and protect your engine.

An added bonus we've incorporated is the built-in button valve. To ensure there is no hot heat pressure built up, always press the button to make sure there is no hot vapors in your radiator before opening the cap.  Pressing the button also allows hot vapors to escape for quicker cooling. 

*NEVER OPEN RADIATOR CAP WHEN HOT.


Features

  • High pressure spring to raising engine boiling point.
  • Safety button to reduce chance of being burned.
  • Release hot vapors to cool down engine faster.
