Default Expansion tank cap pressure question

I have searched the Rave, owner’s manual and the forum for the pressure rating on the correct cap for my 2002 Disco. 1.4 bar is stated in Rave and owners manual and when I convert to psi I come up with 20 psi. My cap is an aftermarket URO cheap part and it says 14 psi … so my question is what is the correct psi for my Disco? I’m doing high mileage tune up and thought this would be a good thing to update. Thanks in advance for any tips and or advise.
