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.
