Style 5888 Valve Stem Packing

This dimensionally stable, firm, high-density PTFE continuous filament fiber packing is useful in slower shaft speed applications.  Its PTFE dispersion reduces friction and prevents leakage through the braid. Style 5888 is resistant to all chemicals except molten uranium salts. It is completely asbestos-free, with very little water absorption.
