STT M23053/12 Class 3

PTFE TUBING
1.5:1 SHRINK RATIO
260°C Operating Temperature
DESCRIPTION:

WEICO's STT series is a PTFE heat shrinkable tubing providing outstanding physical,
chemical and electrical properties. When heated in excess of 327°C, STT will shrink to
two thirds of its supplied diameter.  STT is highly resistant to most fuels, chemical and
solvents while offering outstanding dielectric strength. Because of its high temperature
and low coefficient of friction, Weico's STT is an ideal choice for strain reliefs especially
in high density connectors where soldering iron damage is a problem.  

CHARACTERISTICS:

STT tubing meets MIL-I-23053/12, Class 3.
It is rated for continuous operation from -67°C to+200°C.
