    Oil-Resistant Aramid-Reinforced Buna-N Pipe Gaskets

    Image of ProductInUse. Front orientation. Pipe Gaskets. Oil-Resistant Aramid-Reinforced Buna-N Pipe Gaskets.
    In addition to oil, these Aramid-reinforced Buna-N gaskets resist water and aliphatic hydrocarbons such as ethylene. Also known as ring gaskets, use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection.
    Plain-Back Gaskets for ANSI Flanges
    Gaskets for ANSI flanges are sized so all gasket specifications meet ANSI standards.
    For ANSI Class 150—Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges.
    For ANSI Class 300—Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

    Oil-Resistant Aramid-Reinforced Buna-N Pipe Gaskets with Bolt Holes and Fasteners

    Each gasket comes with enough bolts and nuts to create a connection between two steel pipe flanges. Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. They’re made from Aramid-reinforced Buna-N and resist oil, water, and aliphatic hydrocarbons such as ethylene.
