FIT® Heat-Shrink Tubing
Whether your concerns are
mechanical strain relief,
environmental sealing,
or organizing wires, Alpha Wires
FIT heat-shrink tubing is ideal for
solving many challenges in electrical
and electronic wiring:
Protect substrates from
moisture, UV light, corrosion,
oxidation, dust, chemicals,
abrasion, environmental
conditions, solder joints, and
encapsulates
Insulate wire terminations
and connections, entire printed
circuit boards, from electrical
and environmental conditions
Repair cable splices, insulation
damage and cuts, cable
jackets, and connections,
with permanent or temporary
quick fixes
Relieve strain on cables and
connectors to prevent harmful
flexing or bending
Bundle and organize wire
harness, cable, tubing, and hose
dressing on OEM equipment,
breakouts, bundle in small
spaces, conform to odd shapes
Seal connections, backshells,
and other gaps from moisture
and other contaminants
Identify circuits through color
coding, grouping, and labeling
FIT heat-shrink products
Our FIT heat-shrink tubing offers
a reliable way to protect and
seal terminations or add additional
mechanical ruggedness. FIT
preferred heat-shrink products are
made from premium compounds
under the tightest manufacturing
controls. This means FIT tubing
consistently provides excellent
physical characteristics such as
low longitudinal shrinkage and
wide temperature ranges while
providing an elegant appearance
when used alone or on OEM
equipment.
The FIT line consists of various
tubing types, each designed
with unique attributes that offer
tubing solutions for the broadest
possible range of applications
and environments. FIT products
are always in stock and come
in an unprecedented variety of
package sizes.
Beyond the widely used polyolefin
tubing that is suited to the
broadest range of general-purpose
needs, we offer a number of other
materials for higher or lower shrink
temperatures, wider operating
temperatures, and such special
needs as outstanding chemical
resistance or increased flexibility.

directly into dot matrix printers
(high carbon content ribbon
recommended). A standard ball-

Alpha’s heat-shrinkable pre-
insulated crimp splices completely
seal electrical connections from
corrosion caused by water, salts,
and other contaminants. Unlike
conventional splices, these
adhesive-lined butt connectors
provide a strong reinforced
connection. They are lightweight
and easy to install, too.
Simply insert the wires. The
sleeve’s transparent nylon insulation
lets you inspect wire location and
position your crimping tool fast.
Crimp the splice and then shrink
and seal it with a common heat
gun or other heat source. Reliable
sealing plus quick and easy
installation add up to protection
you can count on whenever
wire splices are required,
including automobile and truck
wiring, outdoor electrical
equipment, marine equipment,
telecommunications equipment,
recreational equipment, and
household appliances.

Selection Guide
1 Measure maximum diameter (E)
and minimum diameter
(F) of combined cable and
ground lead.
2. Find appropriate Alpha
part number and sleeve size
in the cable and sleeve
dimensions chart.
Alpha’s FIT-SLV soldering sleeve
is a one piece, shield ground
termination system featuring a
strong, low-cost soldered
connection that is completely
insulated and encapsulated. It
consists of a heat-shrinkable
thermoplastic sleeve containing a
precisely engineered preform of
fluxed solder and thermoplastic
inserts at each end. When placed
over a cable shield and heated, the
solder melts and flows, connecting
the ground lead and shield. The
outer sleeve shrinks and the
thermoplastic inserts melt,
encapsulating the termination.
The result is a perfectly soldered,
strain-relieved and environmentally
protected termination.
A solder preform ensures exact
quantity of solder and flux,
producing optimum solder
connections for maximum strength
and lowest voltage drop.
Transparent heat-shrinkable
insulating sleeve allows inspection
of termination, and provides
long-life strain relief. Meltable
inserts insure complete
environmental protection.
