Ten black copper ring terminals with red and black heat-shrink tubes

TKDMR 10pcs 1/0 AWG 3/8" Battery Lugs with Heat Shrink Tubing

SKU CH-34F6-WY8ZW

Ten 1/0 AWG copper lugs with 3/8" rings and dual-wall heat-shrink tubing, UL listed for 600 V

  • Certifications and standardsUL Listed
  • Product colorBlack
  • 10-pack with 10 heat-shrink tubes included
  • 100 % annealed copper for maximum conductivity
  • UL & CSA certified 4:1 shrink tube rated 600 V
  • Closed-end design seals out moisture and solder leaks
  • Pre-cut 257 mm tubing speeds up installation

What you get

This pack contains ten 1/0 AWG copper lugs with a 3/8 inch ring and ten pieces of 4:1 dual-wall adhesive heat shrink tubing. The lugs are made from 99.9 percent oxygen-free copper with a corrosion-resistant finish and a closed-end barrel that prevents solder leakage. Each lug can be crimped or soldered using standard tools. The tubing is UL and CSA certified for up to 600 volts and is pre-cut in black and red for quick identification.

Who these suit

The lugs are built for heavy-duty battery cables in automotive, marine, solar, golf cart and general outdoor wiring where vibration and moisture are constant. The adhesive-lined tubing creates a waterproof seal that protects the connection in those environments. Installers who need a different wire gauge, a different stud size or a non-adhesive shrink tube will not be served by this specific kit.

Deciding specification

The critical figure is the 1/0 AWG wire size combined with a 3/8 inch ring terminal; the lug will only fit cables of that gauge and bolts of that diameter. The 4:1 shrink ratio and 600 volt rating on the tubing confirm the insulation level for the circuit. If either the conductor size or the stud size differs, this pack cannot be used.

Questions about this item

How do I crimp the 1/0 AWG lugs and what step do people often miss?

Use a standard crimping tool with no special dies required; the step people miss is sliding the 4:1 dual-wall adhesive heat shrink tubing onto the cable before crimping, then heating it to seal the connection against moisture.

What maintenance or replacement will the heat shrink tubing need later?

The 4:1 dual-wall adhesive tubing is UL and CSA certified for up to 600 V and 257 °C; inspect periodically for cracks or adhesive breakdown in high-vibration marine or vehicle use and replace any damaged sections.

What limit appears first when these lugs run under sustained high current?

The 99.9 % oxygen-free copper lugs handle maximum current flow, but the 600 V rating of the heat shrink tubing is the first limit reached if voltage or temperature exceeds its certification.
