Lugs and insulation supplies in one assortment
KIT-90C includes 50 copper battery cable lugs plus 40 pre-cut heat-shrink tubes: 90 individual pieces. A practical consumables kit for preparing different cable terminations without buying every item separately.
Part 1: 50 copper cable lugs
- 10 lug types covering the listed 8, 6, 4, 2 and 1/0 AWG conductor sizes.
- Thick annealed-copper, closed-end barrel construction for compatible copper cable.
- Check the actual lug's cable and stud markings before assembly. Request the detailed per-size quantities if your project requires many identical ends.
Part 2: 40 adhesive-lined heat-shrink tubes
The included tubing has a listed 3:1 shrink ratio. Select a tube that passes over the unshrunk assembly and recovers to fit the finished cable/lug transition. The adhesive lining helps protect that transition when installed correctly; it does not establish a waterproof rating for the entire connection.
There are 40 tubes for 50 lugs. If every termination needs one insulation piece, plan at least 10 additional correctly sized tubes. Cable, crimper, cutter, stripper and heat gun are not included.
Two sizes must match: cable and stud
AWG describes conductor size; the hole dimension describes the mounting stud. Check both before ordering. 1/0 AWG (one-aught) is different from 1 AWG; this assortment lists 8, 6, 4, 2 and 1/0 AWG, not every size between them.
- Match copper cable construction and barrel dimensions; do not remove strands to make a cable fit.
- Check stud diameter, palm clearance, cable bend space and the equipment's fastening requirements.
- Select tooling by the actual lug, conductor and required crimp profile, not just the tool's maximum capacity.
- Current capacity depends on the cable, terminal, load, temperature and installation; no universal amp rating is implied.
Project fit
For compatible copper battery-cable terminations in automotive repairs, RV auxiliary-power wiring, inverter and battery-bank projects, golf carts and equipment maintenance. These jobs need the right cable gauge, correct stud fit and resistance to vibration through proper mounting and cable support. Confirm any marine or outdoor installation requirements separately; a closed-end barrel does not by itself make the cable entry or assembled connection waterproof.
Installation guidance
- Isolate power using the equipment's battery-disconnection procedure. Match the cable material and stranding, lug barrel, stud hole and specified crimp tooling.
- Cut squarely and strip to the lug's insertion length without removing strands. Slide correctly sized heat-shrink tubing onto the cable before terminating both ends.
- Insert all strands fully into the barrel. Use the specified die/profile, crimp positions and sequence; there is no universal number of crimps for every lug.
- Inspect strand capture, barrel condition and crimp quality against the terminal requirements before fitting insulation. Apply tubing with suitable controlled heat according to its instructions.
- Mount the palm flat on the compatible connection point and tighten to the equipment's specified torque. Support the cable and verify the assembly before energizing it.

Frequently asked questions
Does 90 pieces mean 90 lugs?
No: 50 lugs and 40 tubes.
Can I choose a die by AWG alone?
No. Verify the lug barrel, cable construction and specified crimp profile; equal nominal wire sizes do not guarantee identical dies.
Already have tubing?
Compare KIT-50BL, the 50-lug assortment, and check its size table against your parts list.
