Connector BLOW 43-027# insulated butt splice 4.3 mm / 26 AWG yellow

Insulated butt splice Connector BLOW 43-027# is designed for joining or repairing two electrical conductors with a neat, insulated connection. Sized for a 4.3 mm outer dimension and intended for use with approximately 26 AWG wires, the yellow insulated sleeve provides electrical insulation and mechanical strain relief. This connector is suitable for applications in automotive wiring, small electronics and general electrical repairs where a compact, color-coded butt splice is required.

Advantages

The yellow insulated sleeve offers clear visual identification for wire gauge and helps prevent accidental shorting. The metal crimp barrel inside ensures a secure electrical and mechanical connection when properly crimped. Its compact form factor enables use in confined spaces and contributes to tidy wiring harnesses and repair points. The combination of insulation and strain relief reduces stress on the conductor at the termination point, enhancing durability of the joint.

Suitable for

• Repairing or extending 26 AWG wires in automotive harnesses
• Joining conductors in small electronics and control circuits
• General wiring repairs and maintenance where insulated butt splices are required

Key specifications

• Connector type: insulated butt splice
• Outer sleeve diameter: 4.3 mm (nominal)
• Recommended wire size: approximately 26 AWG
• Insulation color: yellow
• Construction: metal crimp barrel with insulating sleeve

How to use

Strip the insulation from both conductor ends to the recommended length for the crimp barrel. Insert each stripped conductor end into opposite sides of the metal crimp barrel inside the insulated sleeve. Use an appropriate crimping tool sized for the connector and the specified wire gauge to compress the barrel firmly onto the conductors. After crimping, inspect the joint for mechanical integrity and proper insulation coverage. If required, apply heat shrink tubing or additional protective sleeving for environmental protection.

Usage recommendations

Use a matched crimping tool rated for insulated butt splices and the specified wire gauge to achieve reliable electrical contact and mechanical strength. Verify wire gauge compatibility before installation and avoid exceeding the recommended conductor size to ensure correct crimping and insulation fit.
