    If the sealing surfaces are clean and straight, I think I’d use Permatex Anaerobic Flange Sealant, P/N 51531, on it. This stuff is similar to the old OMC Gel Seal and since it is anaerobic, it will set up in the absence of air. Permatex does have a copper based primer to compliment it if you are in a hurry but it will set up overnight without it.
