PSTH Tubing

Elastomeric Polyester, Flexible

Data Sheet

3M PSTH tubing is a high performance,

Product Description

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.

Shrink Ratio

3M PSTH tubing has a 2:1 shrink ratio.

When freely recovered, the tubing will

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 to 50% of its as-supplied internal

diameter. The recovered wall thickness is

proportional to the degree of recovery.
