    Bolts for oil-filled transformer

    The oil-filled transformer has an upper section, which is bolted to a gasketed flange of the oil tank. Transformer has about 2-3 psi of nitrogen, which "helps" in some oil buildup around bolts/ nylon nuts. I realize that nothing is perfect in this world, but is there some remedy for it, like special bolts/nuts, etc?

    is it over filled?
    over heating?

    try evenly tightening the bolts a few lb-ft
    or a new gasket

    without a pic or oil loss qty hard to gauge if it is a problem

    The company I worked for before I retired made nylon coated nuts, bolts and washers for caustic environments.

    But as far as I can see there is no reason for the conservator to be insulated from the main tank so I’m confused as to what you’re trying to achieve.
    The reports of my death are greatly exaggerated.

    Oil loss isn't a factor, rather a nuisance, like those droplets hanging on some bolts. Obviously the gasket is not as perfect as it suppose to be, and replacing it would come at price, and it's not guaranteed this would fix a problem.

    You need to learn how to explain things.

    That's not a leak; it's a calibrated expansion relief fitting.
