TEFLON
HOSE ASSEMBLY
HOSE
PROPERTIES
| Design |
-Teflon®
is a registered trademark of DuPont and is the
trade name for
-Polytetrafluoroethylene (PTFE). |
Temperature
Resistance
|
-(-)70
to 260°C |
| Chemical
Resistance |
-Suitable
for almost all chemicals except few like fluorine
gas, oxygen
-difluoride, chlorine
trifluoride and boiling alkali metals |
| Flexibility
with strength |
-PTFE
hose assemblies (Smooth Bore) have an excellent
vibration
-absorbance and
flexibility at high pressure |
| Non-stick |
-Due
to non-stick nature of PTFE, media passing through
the hose does
-not stuck up, reducing
the risk of bacterial contamination, hence widely
-used in pharmaceutical
and food industry for batch purity. |
| Non-ageing |
-Enormous
Shelve life and resistant to atmospheric conditions. |
| Size
Range |
-Smooth
Bore - 1/4" to 1"
-Convoluted - 1/2"
to 6" |
Braid
for protection & pressure

-SS
304 / SS 316 |
"KFI"
hose assemblies are available in two types of PTFE,
non-conductive (white) and conductive (black). Black
PTFE has been treated with carbon to make it electrically
conductive for dissipation of static
electricity.
