Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Gardner Bender 12-10 AWG Insulated Butt Splice, Yellow, 15 Pack offers a precise, code-ready solution for clean, secure wire-to-wire connections. Designed for reliable performance in electrical and automotive projects, this insulated butt splice ensures that each join stays protected from abrasion and accidental contact while keeping conductors neatly organized in any harness or panel.

Why this insulated butt splice stands out

  • Gauge-accurate color coding: The distinctive yellow insulation clearly identifies 12-10 AWG conductors, making it faster to select the right connector on busy workbenches or in dense wiring harnesses.
  • Insulated construction: Built-in insulation provides immediate protection against short circuits and exposure, reducing the need for additional sleeve or tape while improving long-term durability.
  • Code-compliant reliability: UL Listed and CSA Listed, so you can trust these splices to meet common electrical safety standards and workplace requirements.
  • Convenient packaging: A pegged 15-pack keeps your spare connectors organized and easy to reach, ideal for both professional technicians and DIY enthusiasts who tackle multiple projects.
  • Simple, secure joins: Designed for quick crimping with standard tooling, delivering a solid electrical connection with minimal effort and consistent results.

Ideal use cases

These 12-10 AWG insulated butt splices are well-suited for a wide range of wiring tasks, including automotive harness repairs, household electronics upgrades, lighting installations, and equipment wiring in both professional and DIY setups. Whenever you need to splice two 12-10 gauge wires while maintaining insulation and safety, this Gardner Bender solution is a dependable choice.

Practical tips for best results

  • Ensure wires are within the 12-10 AWG range before crimping to avoid loose or over-tightened connections.
  • Use a crimping tool with the appropriate die to achieve a firm, smooth crimp that seats the conductor and insulation securely.
  • After crimping, perform a gentle tug test to confirm the connection remains firmly seated without any exposed copper.
  • Verify the insulation sits flush around the crimp to maintain protective coverage and avoid snag hazards during installation.

With Gardner Bender’s 12-10 AWG Insulated Butt Splice, Yellow, 15 Pack, you get a dependable, color-coded, and code-friendly solution that streamlines wiring projects. Secure, protected, and readily available in a pegged 15-piece bundle, it’s a practical choice for electricians, automotive technicians, and serious DIYers who value safety and efficiency in every splice.
