1 Remove any oil, grease, water, dirt, etc., by wiping the cable ends and connector.
Remove all sharp edges and burrs from connector.

2 Center tubing over splice connector.
3 Use the light blue outer portion of the flame when using the SIT-1 torch. Do not hold the torch still in one position or concentrate the hot inner flame of the torch on the tubing; this may cause scorching.
4 Begin heating tubing in the center. Recover the central portion of the tubing first by heating around the circumference of the splice. (Keep heat source moving constantly around the circumference of the insulator to
ensure uniform shrinkage of the insulator.)
5 Continue heating around the tubing and out toward one end. Move torch around the tubing until one end is
completely recovered.
6 Repeat the above procedure on the opposite end of the splice, again working the source from the center outward and around the tubing.

Typical Specifications
Insulating and sealing of all 600 V, in-line cable splices from #16 AWG through 1000 kcmil shall be done in
accordance with the instructions provided with the Shrink-Kon™ shrinkable insulators, catalogue Series HS.
The connector insulator must be made of thermally stabilized, homogeneous polyolefin having internally applied
sealant. It must have Underwriter’s Laboratories Listing (UL 90°C, 600 V) and be approved for the use. It must be
usable without additional covering or adhesive both indoors and outdoors, in overhead, direct burial, or submersed
applications at rated voltage. It must not be adversely affected by moisture, ozone, oils, fuels, mild acids and
alkalies, or ultraviolet light. It must be compatible with all commonly used cable jacket materials, including
rubber, plastic, lead, steel, aluminum and copper.
Factory-Applied Sealant
A standard sealant is coated on the entire inside surface of most precut sizes. Tubing is also available without
sealant — consult factory. The sealant is rated for continuous 90ºC operation on non-pressurized cable systems
and aids in sealing out moisture and corrosion.

Cost and Reliability of Heat-Shrinkable
Tubing Compared to Tape
The cost differential in the installation of T&B
heat-shrinkable tubing over taping can result in up to
a 34% savings in labor and overhead. For example,
on a 2/0 aluminum splice, heat-shrinkable tubing can
be installed in 3 minutes, versus 10 minutes of taping.
In addition to the direct cost reduction, there are the
advantages of assured uniformity of wall thickness and
moisture sealing.
Safety Warning: Keep clothing and body parts away from flame.
