    Oil-Resistant Compressible Buna-N Pipe Gaskets with Bolt Holes for Dissimilar Metals

    The included plastic sleeves and washers provide a layer of protection against dielectric corrosion, which occurs when different metals are joined. Commonly called full-face gaskets, these cover the entire face of flat-surface pipe flanges and align with the bolt holes. They’re made of compressible Buna-N to ensure a tight seal. They resist oil, water, and salts. Gaskets are compatible with low-pressure pipe flanges; all gasket specifications are sized to meet ANSI standards. Each gasket comes with one full-length sleeve for each bolt hole, plus two phenolic and two zinc-plated metal washers for each bolt hole. Bolts are not included.
