Ultra-Chemical-Resistant Compressible PTFE Pipe Gaskets
Also called Gore GR ring gaskets, these gaskets are made of soft expanded PTFE, 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. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

Ultra-Chemical-Resistant Compressible PTFE Pipe Gaskets with Bolt Holes
Also known as Gore GR, these soft expanded PTFE gaskets are more compressible than pure PTFE to ensure a tight seal. They are 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. Gaskets for ANSI Class 150 flanges are compatible with low-pressure pipe flanges. Gaskets for ANSI Class 300 flanges are compatible with medium-pressure pipe flanges.

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.

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 that is FDA Compliant 21 CFR 177.1550 is for use with food and beverage.

Ultra-Chemical-Resistant Compressible PTFE Gasket Material
More compressible than pure PTFE, these expanded PTFE gasket sheets and discs ensure a tight seal. They are chemically inert (except to molten alkali metal and elemental fluorine). Cut with a utility knife or gasket cutter.
Sheets are also known as Gore GR.

Premium Steam- and Chemical-Resistant Packing Seals
Made of Gore PTFE, these premium seals are soft, so they conform to fill irregularities caused by wear in valve stems. They are self-lubricating. Use them in applications involving acids, alkalies, brines, and solvents. Cut these seals to size with a knife; then pack them into place.
