16-14 Heat Shrink Butt Connector, 25 pack Free Returns

Pacer TBSE14-25 Heat Shrink Butt Splices are 16–14 AWG blue crimp connectors supplied in a 25-pack, designed to create durable, environmentally sealed wire-to-wire connections with water-resistant adhesive heat shrink insulation.

Pacer TBSE14-25 heat shrink butt splices are used to safely connect one or more wires to another wire in marine, vehicle, and electrical systems. They combine a crimp-style butt splice with heat shrink insulation, creating a protected connection after crimping and heating.

These connectors are designed for 16–14 AWG wire and use blue insulation for easy wire-size identification. When heated, the adhesive-lined heat shrink helps seal the connection against water, condensation, salt spray, and corrosion, making these splices a practical choice for harsh or vibration-prone environments. The Pacer spec sheet identifies butt splices as tinned copper connectors with insulation materials based on splice style and lists applicable features such as 600 V rating, -55°C to 125°C operating temperature, and UL, CSA, and RoHS compliance where applicable.

Check Before Ordering

• Confirm your wire size is 16–14 AWG.
• Confirm the 25-piece package size is correct for your project.
• Use the correct crimping tool for insulated heat shrink butt splices.
• Strip the wire to the proper length before inserting it into the splice.
• Make sure the wire insulation meets the butt splice before crimping to avoid exposed conductor.
• Perform a tug test after crimping and before heating.
• Apply heat evenly from the center outward and avoid burning the connector or wire insulation.
• Do not use this blue 16–14 AWG splice for 22–18 AWG or 12–10 AWG wire unless the wire and connector specifications match.
