Stant
Stant Radiator Cap 21-25lb
Stant Racing Radiator Caps are designed for use on high performance cooling systems. We stock standard SAE "A" size for 2-1/8" OD x 3/4" deep filler necks. These caps can be use for both open (no recovery bottle), and closed (recovery bottle) cooling systems.
High-pressure radiator caps help to insure against overheating. Raising your coolant pressure will raise the coolant boiling point (1 psi adds approximately 1°C to the boiling point, depending on your coolant mixture).
These Stant racing radiator caps are available with two different pressure settings: 20 psi (holds between 18 and 22 psi) or 23 psi (holds between 21 and 25 psi).
Before installing a high-pressure cap, have your cooling system inspected and pressure checked to make sure that it can handle the increased pressure.
