INSTALLATION INSTRUCTIONS
OPEN-RUN TEE TAP COMPRESSION CONNECTORS
FOR AAC, AAAC, ACAR and ACSR CONDUCTORS
Tee connectors are marked with the conductor diameter range, die sizes, minimum press size and FARGO
catalog number. Cable-to-flat tees have 2 or 4-hole NEMA pads. Cable-to-cable tees have pre-filled
compression tube for tap connection.
1. CABLE MAIN With a clean stainless steel wire brush (V-brush type recommended), aggressively
brush the conductor over the entire section where tee will be installed. Immediately apply a generous
coat of FARGO Joint Compound Type UJC or HTJC over the just brushed main conductor.
2. Remove the protective plastic from the main tube ends, taking care not to drop either half as the
connector will separate at its interlocking side joints as plastic is removed. Aggressively wire brush the
I.D. of main tube halves and immediately coat brushed surfaces with FARGO UJC or HTJC compound.
Set aside the untapped tube half on a clean surface.
3. Install the sleeve halves over the damaged conductor area so that the seams between sleeve halves
will be inside the die cavities during compression:
a. Position one of the brush-cleaned & compound-coated sleeve halves centered over the damaged
conductor section and slide the interlocking opposite half into place until ends are flush.
b. Tape wrap near sleeve center, to prevent tube halves from separating at the slide joints until set by
crimping.
4. Select compression dies indicated on main tube. Mount die halves in press and lubricate both die faces
and the tee main compression zone with clean oil or clean plastic bag material (if plastic used as
lubricant, ensure that it wraps completely around the split tube, fully covering both die face during each
compression).
5. Position press at the knurled ring on first tee main side to be crimped. Compress from knurled ring to
tube end. Overlap each crimp by an amount necessary to prevent the formation of ridges between
adjacent crimps. Ensure full die closure with each crimp. To minimize bowing of the connector, keep
the compression zone lubricated equally at both die faces and fully seat main tube in one die half as
dies close.
a. One-Way crimp procedure where damage is close to a deadend, splice or suspension clamp: Press
from short span side to center, remove center tape and press opposite side from center to longer
span end.
6. Once main crimp operations are complete, remove any flash and file or sand for a smooth appearance.
FLAT-PAD TAP (Cable-to-Pad tees)
7. Remove protective plastic from tee tap pad. Wire brush clean the pad surface. Immediately apply a
generous coating of FARGO contact sealant GF-198 (or HTJC, but NOT UJC, compound) to
brushed tee pad surface. Remove excess compound from bolt holes (to keep it out of bolt threads on
nut end). Wire brush mating terminal pad surface (If mating pad is tin plated, clean but do not wire
brush it). Immediately bolt joint together using aluminum bolts, nuts and flat washers (25 ft-lb for ½”
torque). Or, if using stainless steel hardware, add Belleville-type spring washers rated to compress flat
under SST hardware with 40 ft.-lb torque applied.

CABLE TAP (Cable-to-Cable tees)
8. Mark the tap conductor with from the end at a distance equal to the tap tube insertion depth. The
insertion depth is the distance from the open end of the tap tube to knurled ring. With a clean stainless
steel wire brush (V-brush type recommended), aggressively brush the conductor over the entire over
the entire insertion length of the tap conductor. Immediately apply a generous coat of FARGO Joint
Compound UJC or HTJC over the just brushed conductor.
9. Select the compression dies indicated on the tap tube. 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).
10. Insert conductor, rotating to spread joint compound over conductor end as it is pushed to insertion
depth. With the conductor at the insertion depth marked above, move press tool to position dies at the
knurled ring, and compress from knurled ring toward tube end. Overlap each crimp by an amount
necessary to prevent the formation of ridges between adjacent crimps. Be sure that full die closure
occurs with each crimp. To help prevent bowing, apply light machine oil to the die faces, or tube crimp
zone surface, during crimp operation; and be sure that the terminal is firmly seated in one die half while
dies are closing. DO NOT REVERSE CRIMP TAP BARREL.
11. Once crimp operations are complete, remove any flash and file or sand for a smooth appearance.
NOTE: TEE TAPS ARE MINIMUM-TENSION CONNECTORS
