A-11
Style 1965
Superb fexibility & easy
handling
¦ Protects machinery's critical components from abra-
sive media
¦Lowers maintenance and sealing element expendi-
tures
¦Product does not extrude and lasts longer in service
¦Material fexibility and easy handling mean faster
change-out times
¦Non-contaminating components keep end product
and pump area clean
¦Shock resistant withstanding cavitation, pressure
surges and other system upsets
¦Increased thermal stability conserves water

PTFE Packings
Style 5888
Valve stem packing with
superior chemical resistance
¦High density, dimensionally stable—very little water
absorption
¦Ideal for valve and slower shaft speed applications
¦PTFE dispersion ensures a low friction fnish and
prevents leakage through the braid
¦Resistant to most chemicals
Specifcations
Construction: LATTICE BRAID® continuous flament
PTFE braid with PTFE dispersion
Equipment: Check and needle valve stems,
reciprocating rods, rams and plungers,
and rotary applications
