A continuous filament PTFE fiber. Style 5889 is a dimensionally stable yet relatively soft and flexible packing. Treated with PTFE dispersion and an inert ingredient, it's an excellent choice for high speed rotary shaft service in marine, waste/water treatment, and most volatile applications. Pre-shrunk to avoid packing wear and shaft scoring, Style 5889 is also very non-porous. It's often found in sump pumps, chlorinators, alkaline softeners, slip-type expansion joints, strong acid situations, coke plant hot oil pumps, reciprocating rods, rams and plungers.
