Copper Non Insulated Butt Connectors Kit

• Product Material: Crafted from premium-grade red copper with a uniform tin-plated coating, these non-insulated butt connectors provide exceptional corrosion and oxidation resistance.
• Chamfering Design: Precision beveled entry ensure smooth wire insertion for effortless installation.
• Strong Crimps: Heavy-duty seamless butt connector barrels ensures ultra-secure crimps, Wire stop at the terminal center visually confirms full wire seating and proper alignment, ensuring maximum crimping tightness.
• Heat Shrink Tubing Recommended: For maximum waterproof sealing, we recommend insulating the connection with heat shrink tubing to create an airtight moisture barrier.
• Wide Application: These butt connectors are suitable for a wide range of applications including automotive, marine, DIY and Industrial Applications.

Precision Crimping with Raw Copper Terminals

Designed for professionals, these non insulated butt connectors offer a sleek, solderless solution for permanent, low-resistance splices. Built from pure copper, they outperform aluminum or plated alternatives in both conductivity and mechanical strength.

Perfect Match for Non Insulated Ring Terminals

This kit complements our full line of non insulated ring terminals and non-insulated ring terminals, ideal for complete custom circuit building. Whether you're working on automotive, industrial, or marine systems, you can trust these connectors to perform.

Ready for Shrink Tubing Protection

Pair your crimps with heat-shrink tubing, heating shrink tubing, or shrink heat shrink tubing to add water resistance and strain relief. This kit offers insulation flexibility—use bare, wrap with tape, or seal with shrink tubing as needed.
