Replaces / Cross-Reference Part Numbers

• Universal replacement for standard crimp-style butt connectors for 16-14 AWG wire applications requiring a waterproof seal.

Compatibility & Fitment

• Fits wire sizes from 1.5mm² to 2.5mm² (16-14 AWG)
• Suitable for use with solid and stranded copper wire
• Ideal for automotive, marine, industrial, and home electrical wiring applications

When to Replace

• For creating new, permanent wire splices
• When repairing damaged, cut, or frayed wires
• To protect electrical connections from water, moisture, salt, and corrosion
• In applications where a reliable, sealed connection is required without a separate soldering iron

Installation Tips

• Strip wire insulation by approximately 1/3 inch (8mm) on each end.
• Insert wires into the connector, ensuring the bare ends overlap within the solder sleeve.
• Apply heat evenly using a heat gun, starting from the center and moving outwards.
• Watch for the tubing to shrink and the solder to melt and flow, encapsulating the wires.
• Continue applying heat until the adhesive rings at both ends melt and seal the connection.
• Allow the connector to cool completely before handling or applying any stress.
