Braided from 100% PTFE filament, PTFE Soft Filament Packing is thoroughly impregnated with a PTFE suspensoidal blocking agent and our proprietary break in lube. Our unique blend of lubricating oil eases friction during startup and operation. A soft but dense and stable packing is ideally suited for chemical process pumps where extreme chemical resistance and extremely low shaft friction are required.
