Has anybody any experience/recommendations on a thread sealant for hot oil (heat transfer medium) for temperatures up to 340degC. Pressures are normally at 700kPa max. Also it would need to be able to be dismantled with hand tools without applying heat.

Alternatively what would the highest temp rating of an appropriate sealant be, as mostly these threaded connections are not in the main flow line and not subject to the highest temps. I have used Loctite #567 at lower temps but its rated max is 204degC.
