I would use whatever the company recommends. I have tried to disassemble stuff put together with the high strength Loctite and it can be nearly impossible even with two good wrenches. These fittings generally have very good mechanical connections and most have reusable parts incase something does not fit. I feel about high strength Locktite, like I feel about 5200: I would only use it on something where it is required by the manufacturer or something I never, ever intend to remove. As you are aware there are various strengths of Locktite, so the lesser might be fine. Some of the old fittings (Norseman, no longer around, I think) used to require sealant because they did not want water to freeze in them and break seals. The folks who leave their rigs up in winter have had cracked swages and I guess that could be a problem in the voids. FWIW.
