Copper Non Insulated Butt Connectors Kit

Brand: Haisstronica

AWG: 26-6

Haisstronica’s non insulated butt connectors kit is engineered for professionals who demand clean, low-resistance wire joins with maximum conductivity. Each non insulated butt connector is crafted from high-purity copper, making it ideal for high-performance electrical systems where strength and precision matter.

This set pairs perfectly with non insulated ring terminals, allowing you to build full crimp-style circuits with confidence. Whether you’re wiring vehicles, control cabinets, solar systems, or marine electronics, these connectors deliver the durability you expect—without insulation bulk.

Use them alongside heating shrink tubing or shrink heat shrink tubing for added protection and moisture sealing. Unlike insulated alternatives, these raw terminals give you full control over your wiring layout and ensure clean contact with non-insulated ring terminals.

From mechanics to electricians, this kit empowers you to get the job done right—every time.

Features:

• 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.
