Select proper size. The tubing's RECOVERED DIAMETER must be less
than the diameter of the area to be insulated and the EXPANDED DIAMETER must
be large enough to pass over the existing insulation.
Cut tubing to length, allowing for a minimum overlap of 1/4" over the
existing insulation on each side of the splice.
Slide the cut tubing over the existing insulation, and out of the
way. Make the splice in the desired fashion. If soldered or
brazed, all to cool.
Slide the tubing over the center of the splice, with equal overlap on both
Apply heat evenly over the length and outer diameter of the tubing, until
it is evenly shrunk and conforms to the shape of the splice. Allow to
cool before applying physical stress.
Recommended heat range is 120 deg C (250 deg F) to 250 deg C (485 deg F)
with 200 deg C (400 deg F) being ideal. Any commercial heat gun can be
used, or shrinking can be done in an oven. Use of open flame is not
recommended, as the uncontrolled heat may cause uneven shrinkage and/or
physical damage to the material causing insulation failure.
Do NOT store Heat Shrink Tubing where temperatures may exceed 100 deg F.
