I’d be interested to hear the views of others on possible electro chemical corrosion between Ex brass cable glands / copper sealing washers & Ex aluminium enclosures. Both Pirelli & Hawke recommend the use of nickel or tin plated glands, but one Ex panel manufacturer recommended using brass glands with silicone grease applied to the threads???

Thanks in advance,

Alan
