Applications
MiniSeal wire-to-wire splic-
ing products offer solutions
for hundreds of aerospace
and defense applications.
These environment-resistant
splices provide excellent
reliability, long term per-
formance, MIL-S-81824/1
qualification, and a low
installed cost.
MiniSeal crimp splices con-
sist of a plated copper
crimp barrel and a sepa-
rate, heat-shrinkable, trans-
parent sealing sleeve. They
can be used on a combina-
tion of wires, from 1:1 to
10:10. MiniSeal splices are
one of the smallest, lightest,
and most environment-
resistant splices available.
They preserve the electrical
integrity of the splice by
preventing the penetration
of liquids and the resulting
chemical and galvanic
corrosion.
Product Selection Process
1. Determine the type of
splice required.
■
Stub (parallel) splice:
Butt (in-line) splice:
■
2. Determine which crimp
barrel plating is required:
■
Table A provides the
CMA of typical conduc-
tors. (Both CMA and mm
give the same results, so
choose either CMA or
mm as your unit of
measure for selection
purposes and continue
to use it for all your
selection criteria.)

2
Tin plating,
recommended for tin
or silverplated wire
Nickel plating,
recommended for
nickel-plated wire, or
silver-plated wire in
applications above
150°C [302°F].
■
4. Select the color code for
the size crimp barrel
required. Using Table B
(page 8-23), select the
crimp barrel—color-
coded red, blue, or
yellow—for the CMA or
mm you calculated.
2
5. Determine the type of
sealing sleeve required.
Some wire insulations will
not fit in the holes of the
sealing sleeve inserts, so
be sure to compare the
internal diameter of each
hole with the outer
diameter of the wire(s)
you intend to insert in
that hole. To create a
reliable seal, place a
maximum of two wires
in any hole of the sealing
sleeve.
6. Select the part number.
Turn to the MiniSeal part
number selection tables
(Tables C and D, page
8-23 and 8-24) and find
the table for the type of
splice (stub or butt)
required.
Using the appropriate
table, find the crimp
barrel size range and
the size and number of
wires for your applica-
tion. Then select the
part number for the type
of plating required. The
color code accompany-
ing that part number
should match the color
code you arrived at in
Table B, confirming that
the part number you
have selected is correct.
3. Calculate the size of
crimp barrel required.
Using the CMA/mm
2
worksheet on the next
page, calculate the total
cross section to be
spliced by adding the
circular mil area (CMA)
or square millimeters
(mm ) of each wire.
2
Stub splice:
Select the
barrel that will accommo-
date the total cross
section.
Butt splice:
Select the
smallest barrel that will
accommodate the
largest CMA/mm
2
required. (Refer to the
example in the work-
sheet for a more specific
description.) If the
CMA/mm
2
of the smaller
side of a butt splice is
too small for the size
barrel required to fit the
larger side, increase the
CMA/mm
2
—either by
doubling back one wire
(stripping the conductor
twice the length you
would ordinarily strip it
and then folding it back)
or by adding a filler wire.
Stub splice: Add the
CMA or mm of all wires
together.
2
Butt splice: Calculate
each side separately
(see example on the
worksheet).

Worksheet
Example:
Application: A butt splice
with three AWG 22 wires in
one side and one AWG 18
wire in the other side:
The CMA for AWG 22 wire
in Table A is 754.
Side one is therefore calcu-
lated as follows:
CMA = 3 x 754 = 2262
The other side, where the
CMA for AWG 18 is 1900, is
calculated as:
CMA = 1 x 1900 = 1900
Using Table B to select the
smallest crimp barrel that
will easily fit 2262 CMA, the
blue barrel is the correct
choice.
