TFE Filament
Interbraid construction. TFE fibers are treated with a TFE dispersion which fills
and seals all interstices in the packing fibers. After braiding, a TFE coating is
applied and the packing is forced air dried. This packing will not wick.
Recommended for valves, expansion joints, and static applications. For all
severe chemical and corrosive services where an inert packing material is
essential. For temperatures to 500°F/260°C; PV factor 650,000; pH range 0-14.
Excellent valve stem packing for all chemicals and corrosives; inert to all fluids
except molten alkali metals. Packaged in 10 lb. boxes which may be broken for
smaller orders.

TFE Packings
PTFE Filament Impregnated with PTFE
Interbraid construction. Pre-lubricated yarns to provide a softer, more flexible
packing with improved peripheral speed characteristics and exothermic
properties. Recommended for any equipment where braided packings are
commonly used. Dynamic and static applications. For the most severe services.
All oxidizers and corrosives with one exception: molten alkali metals. PV factor
650,000; pH range 0-14; speeds up to 1200 FPM. No glazing at higher speed
applications, inert, virtually indestructible, lower coefficient of friction, thermal
resistance to 500°F/260°C; and high compressive strength. Packaged in 10 lb.
boxes which may be broken for smaller orders.

Teflon
®
Cord Packing
100% pure PTFE round packing and gasket material. Self
lubricating and non-hardening. A tough fibrous PTFE core
and low friction surface is more chemically inert than
conventional string packings and has greater resistance to
cold flow under pressure. Recommended for flanges, valve
or faucet stems, pump housings, stuffing boxes, rotary
pump shafts, reciprocating rods, centrifugal pumps, rams
and expansion joints. For most acids, alkalies, solvents, fuels,
air, water, steam, refrigerants, gases and liquified gases.
Temperature from -450°F to 500°F. Not recommended for oxygen service.
Packaged on plastic spools with shell. Twelve rolls per plain white display box.
