| 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

"STAR" 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.
