Rated at 16 psi but wouldn't hold 10 psi. The same problem I had with the one that was on the car so it went back.
I always test the pressure of a radiator cap before I put it on the vehicle, new or not. The pressure tested good on this new cap. Good buy for the price.

Fits just right
Have not had a chance to install this yet but it was a good price and in stock which is important when I am looking for parts.
It was as good as I expected. I would purchase again but like everything else, they were better quality years ago. I really like to have these on my cars because of the pressure relief lever. It can save you from getting burned by hot coolant. (Follow safety precautions).
