IDEAL Industries 84-9091 Non-Insulated Parallel Splices

It is a non-insulated splice, so the crimped barrel is bare metal. You have to insulate the joint yourself after crimping, normally with heat shrink tubing or electrical tape, before the connection can be left in service.

Each order quantity covers 1,000 pieces of the 84-9091 splice. That is a bulk electrician's pack rather than a small counter card, so it suits panel shops, fleet maintenance, and MRO stock rooms crimping the same wire range repeatedly.

The barrel is tin-plated brass, which gives corrosion resistance on the metal itself. Because the 84-9091 is non-insulated, any moisture protection has to come from the insulation you apply over the crimp, so in damp locations use adhesive-lined heat shrink over the finished joint.

The barrel has internal serrations that bite into the strands to resist pull-out and lower electrical resistance, and the seam is butted so it will not split when crimped at full pressure. It still needs a proper crimp tool matched to the barrel; pliers will not deform the barrel correctly.

Go non-insulated, like the 84-9091, when you want to control the insulation yourself (heat shrink for moisture, or a joint buried in a sleeve or conduit body) or when the finished diameter has to stay small. Choose an insulated splice from the IDEAL crimp terminal line when you want the barrel covered in one step and the color coding to identify wire range at a glance on inspection.
