Product description
3M™ Heat Shrink Tubing PSTH is a
high performance, rugged heat shrinkable
tubing designed for harsh operating
conditions. The tubing is made from
exible elastomeric polyester and has a
continuous operating temperature range
of –55°C (–70°F) to 150°C (302°F).
PSTH tubing is resistant to a wide range
of solvents and chemicals including
aviation fuel, diesel fuel, lubricating
oils and hydraulic uid. 3M PSTH
tubing is specically designed to pass
the SC-X15111C military specication
but also meets the functional requirements
of AMS-DTL-23053/16*.
Typical applications
PSTH tubing was developed for
wire harness applications on military
ground vehicles and is well suited for
applications where conditions call for
a high-performance heat shrink tubing,
particularly where the tubing will be
exposed to petroleum based uids. PSTH
is also an excellent choice for heavy duty
equipment and off-road vehicles.
Shrink ratio
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.
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
shrink snugly over the component to
be covered. Example: PSTH tubing,
3/8", black, spools.
