TIESELX Heat Shrink Bullet Connectors Kit – Waterproof Male & Female Wire Terminals (22–10 AWG)

Product Overview

The TIESELX Heat Shrink Bullet Connectors Kit provides male and female bullet terminals for secure, detachable low-voltage wire connections. Crimp a terminal onto each wire, connect the matching pair, and apply heat to seal the joint.

The adhesive-lined, dual-wall heat-shrink sleeve helps protect the connection from moisture, dust, and corrosion when installed correctly. The compact round design also fits neatly into tight wiring harnesses and inline connections.

The kit covers 22–10 AWG and comes in 110-piece and 130-piece options, with red, blue, and yellow terminals for different wire sizes.

Key Features

• Sealed heat-shrink connection: The adhesive-lined sleeve shrinks around the wire to help protect the joint from moisture, dust, and corrosion.
• Male and female bullet terminals: Connect and disconnect wires by hand when servicing a circuit.
• Tinned copper contacts: Provide reliable conductivity and added corrosion resistance.
• Color-coded sizes: Red, blue, and yellow sleeves make size selection easier.
• Compact round design: Fits well in tight wiring harnesses and inline applications.
• 3:1 shrink ratio: Allows the sleeve to contract tightly around the connection.
• Organized storage case: Keeps terminals sorted and easy to access.
• Two pack options: Choose 110 pieces for smaller jobs or 130 pieces for larger projects.

Wire Gauge and Color Coding

Match the terminal to the wire gauge before crimping.

Use a terminal within the specified range for the conductor. The wire should fit fully into the barrel without forcing or leaving loose strands exposed.

Male and Female Bullet Terminals

Each connection uses a matching male and female terminal.

The male terminal has a rounded pin that fits inside the female terminal. Once crimped onto the wires, the two halves push together to complete the connection.

You can separate them by hand when you need to remove or service a component. The round profile also makes them a practical choice for compact wiring runs.

Applications

Use these heat-shrink bullet connectors for a wide range of low-voltage wiring projects:

• Automotive and 12V accessory wiring
• Motorcycle and powersports wiring
• Marine and RV circuits
• Trailer wiring harnesses
• Car audio and speaker wiring
• Outdoor lighting
• Battery and accessory connections
• DIY electrical projects

For exposed or moisture-prone installations, heat the sleeve evenly and make sure the adhesive-lined tubing seals around the wire.

How to Install

1. Disconnect power before working on the circuit.
2. Strip approximately 6–7 mm of insulation from the wire.
3. Insert the conductor fully into the terminal barrel.
4. Crimp the barrel with a suitable crimping tool.
5. Install a male terminal on one wire and a female terminal on the other.
6. Push the two terminals together until they seat securely.
7. Apply even heat with a heat gun until the sleeve contracts around the wire.
8. Let the connection cool.
9. Give the wire a gentle pull to check the crimp.

Avoid overheating or scorching the heat-shrink sleeve.

Frequently Asked Questions

What are heat-shrink bullet connectors used for?

They join two low-voltage wires with a detachable male-and-female connection. They work well for automotive, marine, RV, motorcycle, trailer, audio, and other wiring applications.

Are these bullet connectors waterproof?

The adhesive-lined sleeve creates a sealed connection when installed correctly. The connection is IP67 rated when properly sealed.

What wire sizes do these connectors fit?

The kit covers 22–10 AWG through its red, blue, and yellow sizes.

Do I need both male and female terminals?

Yes. A complete bullet connection requires a matching male and female terminal.

Do I need a crimping tool and heat gun?

Yes. Crimp the terminal first, then use a heat gun to shrink and seal the sleeve.
