PSTH Tubing
Elastomeric Polyester, Flexible
Data Sheet
Product Description
3M
™
PSTH tubing is a high performance,
rugged heat shrinkable tubing designed
for harsh operating conditions. The
tubing is made from flexible elastomeric
polyester and has a continuous operating
temperature range of -55°C (-70°F) to
150°C (302°f). PSTH is resistant to a
wide range of solvents and chemicals
including aviation fuel, diesel fuel,
lubricating oils and hydraulic fluid. 3M
PSTH tubing is specifically designed to
pass the SC-X15111C military
specification but also meets the
functional requirements of MIL-DTL-
23053/16.
Typical Applications
3M PSTH tubing is primarily designed
for wire harnessing applications on
military ground vehicles. It was primarily
developed for the M-1 tank program, but
is well suited for any application where
conditions call for a high performance
heat shrink tubing, particularly where the
tubing will be exposed to petroleum
based fluids. PSTH is also an excellent
choice for heavy duty equipment and off-
road vehicles.
Standard Color
Black.
Standard Packaging
Spools.
Ordering Information
Order PSTH Tubing by product name,
size equivalent to the expanded inside
diameter, package type and color. Always
order the largest size that will shink
snugly over the component to be
covered.
Example: PSTH, 3/8", black, spools.
Shrink Ratio
3M PSTH tubing has a 2:1 shrink ratio.
When freely recovered, the tubing will
shrink to 50% of its as-supplied internal
diameter. The recovered wall thickness is
proportional to the degree of recovery.
