Reinforced with fiberglass filler for strength, these PTFE gaskets won’t thin out when compressed. They resist hydrocarbons, solvents, refrigerants, and moderate concentrations of acids. 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. All gaskets are compatible with low-pressure pipe flanges and are sized to meet ANSI standards.
