SVAAR 132-piece butt splice kit

This kit contains 66 uninsulated butt terminals and 66 pieces of 3:1 adhesive-lined heat shrink tubing. Terminals are made from seamless bare pure copper and cover four wire gauges from 4 AWG to 12-10 AWG. The UL Listed components suit automotive, marine and general DIY wiring tasks where a sealed crimp connection is required.

Check wire gauge and crimp tool before ordering

The assortment includes 30 terminals for 12-10 AWG, 20 for 8 AWG, 10 for 6 AWG and 6 for 4 AWG. Verify that your existing wiring falls within these sizes and that you have a suitable crimping tool for uninsulated copper splices. A heat source such as a heat gun is also needed to activate the adhesive-lined tubing.

Suits installers needing multiple gauge coverage

Electricians and hobbyists who work across 4 to 12-10 AWG will appreciate the single-kit convenience. Users who only need one specific gauge or prefer pre-insulated connectors should look at a dedicated pack instead.

Questions about this item

What comes in the 132-piece kit and what else is needed?

The kit contains 66 bare pure copper butt splices (30×12-10 AWG, 20×8 AWG, 10×6 AWG, 6×4 AWG) plus 66 pieces of 3:1 adhesive-lined heat-shrink tubing rated for 600 Volts. A crimp tool and heat source are required but not included.

How do I choose between the four wire-gauge sizes in the kit?

Match the splice to the wire gauge you are joining: use the 12-10 AWG splices (30 pcs) for 12-10 AWG wire, 8 AWG splices (20 pcs) for 8 AWG wire, 6 AWG splices (10 pcs) for 6 AWG wire, and 4 AWG splices (6 pcs) for 4 AWG wire.

What does the 600 Volt rating on the heat-shrink tubing mean in practice?

The 3:1 dual-wall adhesive tubing is UL Listed for 600 Volts, so when shrunk over a properly crimped splice it provides an insulated, hermetic seal rated for circuits up to 600 Volts in automotive, marine or general wiring.
