The only thing on a cooler system that needs sealant would be the NPT fittings into the cooler if you use that type. A high temp paste sealant seems to work best. AN fittings use no sealant at all as the seal occurs in the tapered fit and not at the threads. The Mocal fittings have seals on them (provided you bought the recommended ones from Mocal) and don't need anything additional. That's all in my DIY BTW..
