INTRODUCTION:
HOW TO SELECT THE CORRECT SIZE
TUBING FOR YOUR APPLICATION
Heat Shrink Tubing, unlike many other products is designed
to change shape when installed. Correctly sized tubing will
conform to the substrate over which it is applied. It shrinks
in diameter and in general overall length. This can make it
especially tricky to select the right size for your application.
This guide was put created to help with that process.
Recovered ID vs.
Size of Substrate
To achieve a good robust installation
of heat shrink tubing it is important
to get the best fit of the tubing to
the substrate. To do this, the tube
needs to shrink by at least 20% of its
supplied size but not so far that the
tube reaches its fully recovered size. It
is best to have at least 10% unresolved
recovery after the tube is installed.
Example: RNF-100 size 1” recovers
to a maximum of 0.50”. It should
be used for applications where the
expected recovered size is between

0.50”+ 0.05” (i.e.-10%
of 0.5”) = 0.55” to;
•
1” - .2” (i.e. - 20% of 1.0”) = 0.80”
Or in other words, it is intended to cover
something that measures between
0.55”- 0.80” outside diameters.
Will the heat shrink tubing work in
the zone outside the recommended
installation window? Maybe, but it
will not give optimal performance.
Always select the biggest size tube
that will fit the application. It will be
easier to install and achieve the target
wall thickness on of the installed tube.
This will give a more robust solution.

Length Shrinkage
Just as the tubing will shrink in diameter,
it will also shrink slightly in overall
length during the recovery process
(in general – in some case it can grow
in length). Different products have
different longitudinal shrinkage %’s.
Please consult with a Field Applications
Engineer if this is a concern prior to
placing an order. Make sure to account
for this when specifying the cut length
needed or when cutting the tubing
in-house. When using a long length of
tubing, it will need to be cut longer than
the distance it needs to cover because
of the shrinkage during recovery.

the final installed length required.
The tube will change length during
recovery. The more you shrink
it the greater the longitudinal
change. The long change is noted
in the product specification. Use it
when calculating the cut length.
Installation Do’s and Don’ts
•
Do not force the supplied tube over
something by stretching it. This can
cause it to tear during recovery
•
Since heat shrink tubing is
supplied at a minimum expanded
diameter, always use the specified
Expanded ID dimension. Do not
assume that the tube will be
delivered at exactly the same
dimension every time. However,
it will always meet the specified
minimum expanded ID dimension.
•
•
Do not assume the tube will
always shrink to the same fullyrecovered dimensions. Always use
the specified dimensions for the
recovered internal diameter of the
tube. Sometimes the tube will shrink
a little more than the Recovered ID
specified, but it will always meet
the maximum specified dimension.
Do not cut the tube length to be
•
Do not recover the tubing over
something with sharp edges, they
can cut the tubing or puncture
it which results in the tubing
splitting during installation.
•
Follow the installation guidelines,
especially the guideline on
temperature. At too low a
temperature the tubing may not fully
recover. At too high a temperature
it may show burn marks or split.
•
If you use a heat gun to recover
the tubing, expect to see some
wrinkles. This is caused by nonuniform heating of the tubing (chill
marks), but generally has no effect
on the performance of the tubing.
Recommended recovery is in an oven
to give uniform recovery around the
entire circumference of the piece,
or with a heat gun that allows the
substrate to come up to temperature
and assists in full recovery.
•
If you have any questions when
selecting which size tubing is
appropriate for your application
please consult with one of our FAE’s.
