    Ultra-Chemical-Resistant Compressible ePTFE Pipe Gaskets

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant Compressible ePTFE Pipe Gaskets.
    Also called Gore GR ring gaskets, these gaskets are made of soft expanded PTFE (ePTFE), which is more compressible than pure PTFE to ensure a tight seal. They are chemically inert (except to molten alkali metal and fluorine compounds). Use them with raised-surface pipe flanges; they fit the surface inside the bolt holes and do not interfere with the bolt connection. All gasket specifications are sized to meet ANSI standards.
    Plain-Back Gaskets for ANSI Flanges
    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.

    Gasket Tape for Pipe Flanges

    Because this expanded PTFE tape is thicker than other gasket tape, it fills the irregularities on rough-surfaced flanges when compressed for a tight seal. This gasket tape is chemically inert, except to molten alkali metal and elemental fluorine.

    Gasket Tape

    Very soft and conformable, this expanded PTFE gasket tape compresses into an extremely thin profile. Use it to create a leak-resistant seal in tight-tolerance applications, such as on precision machinery. This tape is chemically inert, except to molten alkali metal and elemental fluorine.

    Ultra-Chemical-Resistant Compressible ePTFE Pipe Gaskets for Low Stress-to-Seal Flanges

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant Compressible ePTFE Pipe Gaskets for Low Stress-to-Seal Flanges.
    Often used with fiberglass flanges where you want to avoid overtightening, these gaskets seal under low torque. They’re made of soft expanded PTFE (ePTFE) that is also known as Gore UPG. Use them to fill gaps in pitted and corroded flanges and compensate for uneven bolt load due to vibration or incorrect installation. They’re chemically inert, except to molten alkali metal and fluorine compounds. All of the gasket specifications are sized to meet ANSI standards. They’re compatible with ANSI Class 150 flanges, so you should use them with low-pressure pipe flanges.

    Image of ProductInUse. Front orientation. Pipe Gaskets. Ultra-Chemical-Resistant Compressible ePTFE Pipe Gaskets with Bolt Holes for Low Stress-to-Seal Flanges.
    Form a seal even under the low torque needed for fiberglass flanges. Also known as Gore UPG, these gaskets are made from soft expanded PTFE (ePTFE). They fill gaps in pitted and corroded flanges and make up for uneven bolt load resulting from vibration and incorrect installation. They’re chemically inert (except to molten alkali metal and fluorine compounds). Commonly called full-face gaskets, they cover the entire face of flat-surface pipe flanges and align with the bolt holes. All gasket specifications are sized to meet ANSI standards.
