Similar to Style 5889, but designed for slower shaft speed applications, Style 5888 is a dimensionally stable, firm, high density PTFE continuous filament fiber packing material. It exhibits a superior resistance to all chemicals except molten uranium salts. Style 5888’s high density dimensionally stable design provides for very little water absorption, while the PTFE dispersion ensures a low friction finish and prevents leakage through the braid. It features excellent mechanical strength and is completely asbestos-free. This packing is often used in check and needle valve stems, reciprocating rods, plungers, rams and valves of safety injection systems.
