Radiator cap

I think the rubber in my Radiator cap is gone as it's leaking coolant

Wonder if anyone knows where I can get a radiator cap replacement from?
(brand, model number, price, where..) is much appreciated.

thanks in advance.

After a long search and a lot of coolant, finally I think I got one that fits, and here is what I replaced it with:

Brand: CPC
Model: 562-100
Price: $12
Availabilty: Any Auto-store like Repco, AutoOne, SuperCheap etc

if anyone using a different Radiator Cap please share, sometime is good to know what is everyone using out there.

The radiator cap is designed to hold a certain pressure in the coolant system. Most caps hold 8 - 12 PSI. This pressure raises the point in which the coolant will boil and maintains a good, stable system. If your cap does not hold enough pressure, then the car engine could overheat on hot days since the system never becomes pressurised. By raising the relief pressure all it means is the water in the rad can be cooled by the airflow for longer just before it recirculates.
