UNI-GRIP SPLICES FOR
AAC, AAAC & ACAR CONDUCTORS
The Uni-Grip compression splice assembly for Alloy, ACAR and All Aluminum consists of a
pre-filled aluminum body. Each fitting is marked to show FARGO, catalog number, conductor
diameter range and installation die size. . Repair splices have catalog number marks that
include suffix “XL” followed by and the damaged conductor cutout length in inches.
1. Prior to installation the conductor must be clean, straight and in lay. Any bend in the
conductor section inserted into the splice will tend to make the splice body bow during
compression.
2. Mark each conductor end at a distance equal to the insertion length. The insertion length
is the distance from the tapered end of the splice to the center of the splice.
3. With a clean stainless steel wire brush (V-brush type recommended), aggressively brush
the aluminum conductor over the entire crimp zone. Immediately apply a generous coat of
FARGO Joint Compound Type UJC or HTJC over the entire insertion length of the
aluminum conductor.
4. Remove the protective plastic and the end plug from one end of the splice. Insert the
conductor into the mouth of the splice using the mark applied in step 2 as an indicator of
complete insertion.
5. Select the compression dies as marked on the splice body. Mount die halves in press and
lubricate both die faces and the splice body compression zone with die lubricant stick,
clean oil or clean plastic bag material (if plastic used as lubricant, ensure that it wraps
completely around the deadend tube, fully covering both die face during each
compression). Make the first compression at the knurled ring (near center) and continue
crimping toward the tapered end. Ensure full die closure with each crimp and overlap
crimps by an amount necessary to prevent the formation of ridges between adjacent
crimps. Continue crimping until the end of the splice has been crimped. To minimize
bowing of the splice, keep the compression zone lubricated equally at both die faces and
fully seat splice body in one die half as dies close.
6. Repeat above procedure for other end of the splice.
7. Remove excess joint compound and any marking tape. Remove flash from the splice body
and file or sand for smooth appearance.
NOTE: DO NOT COMPRESS IN THE REVERSE DIRECTION.
DO NOT APPLY TENSION TO THE CONDUCTOR PRIOR
TO COMPLETION OF ALL COMPRESSION.
