Which gaskets work in flange isolation kits?
Customers will occasionally ask for a flange insulation or isolation kit or gasket to electrically insulate one flange from the mating flange. Kits are available from a variety of distributors and include an insulating gasket along with a sleeve for the bolts and insulating washers to be installed under the steel washers and nuts.
