A…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 washer to be installed under the steel washers and nuts.
A Garlock subsidiary, Garlock Pipeline Technologies (GPT) specializes in flange isolation and can be found at www.gptindustries.com for all your flange isolation needs. We do offer many gasket styles with good electrical insulating properties (Dielectric Breakdown Voltage values are available from Application Enginnering).
