Taukealugs 130-Piece Battery Ring Terminals & Butt Connectors Kit — Tinned Lugs and Butt Terminals with Adhesive-Lined 3:1 Heat Shrink Tubing

A complete 130-piece set of tinned, non-insulated copper ring terminals and butt connectors paired with adhesive-lined 3:1 heat-shrink sleeves for durable, low-resistance battery and power cable connections.

This two-sided Taukealugs assortment equips you with a broad range of ring terminals, butt connectors and matching heat-shrink tubing in a compact, partitioned carry case. Each side of the box supplies 65 carefully sized components: one side furnishes bare copper non-insulated butt connectors across AWG8, 6, 4, 2 and 1/0 gauges plus heat-shrink sleeves; the other delivers heavy-duty copper ring terminals that cover common stud sizes and the same protective shrink tubing. Components are manufactured from low-resistivity T2 purple copper with corrosion-resistant surface treatment and are organized with clear size markings for fast selection on the job or in the workshop.

What sizes and quantities are included in this set?

The kit contains a total of 260 pieces when counting both terminals and sleeves: 130 metal connectors and 130 adhesive-lined heat-shrink tubes. One side has 65 non-insulated butt connectors (AWG8 x15, AWG6 x15, AWG4 x15, AWG2 x10, AWG1/0 x10) plus 65 shrink tubes. The other side includes 65 ring terminals across multiple stud and wire size combinations plus 65 matching shrink tubes.

• Butt connector mix: AWG8, 6, 4, 2, 1/0—quantities match common wiring needs.
• Ring terminal range: fits 1/4", 5/16", 3/8" studs across AWG8–1/0 gauges.
• 65 adhesive-lined 3:1 heat-shrink sleeves per side for seal and strain relief.

How do these connectors perform electrically and mechanically?

Parts are stamped from T2 low-resistivity copper and given a surface treatment to resist corrosion, providing stable conductivity for power and battery circuits. Barrels are flared to allow easy wire insertion, and after crimping they hold the conductor securely so wires won’t pull free. The terminals meet UL and ABYC-tested performance expectations for temperature resistance and mechanical strength.

• T2 copper construction minimizes voltage drop in high-current runs.
• Flared openings and burr-free barrels simplify crimping and improve contact.
• Heat-shrink sleeves add adhesive sealing and abrasion resistance.

How does the 3:1 adhesive-lined heat-shrink help long-term connections?

The included heat-shrink sleeves reduce environmental exposure at the crimp and provide strain relief where wire meets terminal. The 3:1 shrink ratio allows for a tight, conforming seal over differing barrel sizes, while the internal adhesive flows when heated, creating a moisture-blocking bond. This combination lowers corrosion risk and keeps mechanical stress from loosening the crimp over time.

• Adhesive-liner forms a watertight seal around the crimped joint.
• 3:1 shrink ratio fits a range of barrel diameters for reliable coverage.
• Heat-shrink adds mechanical reinforcement to prevent flex fatigue.

Who is this kit designed for? Taukealugs engineered this assortment for electricians, marine technicians, automotive and RV owners, and DIYers who need a ready supply of quality copper terminals and matching shrink sleeves. The organized double-sided case with labeled compartments helps professionals and hobbyists quickly find the correct size on-site or at home, making it a versatile toolbox staple when you need dependable electrical terminations without sourcing parts individually.
