For this job I don't think it matters too much which product. Those aviation ones are usually pretty good as long as it says it is suitable for rubber. A smear of gasket silicone on the rings would also work but the one I had was a brown one like contact adhesive. Can't remember what I even had that for, no doubt it's not the right thing to use with coolant orings. Really Orings should not need any sealant on them because they are designed to seal by compression against the metal faces. Sealant will only help if the faces are corroded to help fill the pits, if you're lucky.
