Haisstronica bullet connectors feature pure copper construction and 3:1 heat-shrink tubing, giving every male and female bullet wire connector excellent conductivity with a waterproof, dustproof seal. Designed for quick snap-together connections, each bullet connector ensures reliable, risk-free performance for technicians and home DIY projects.
220PCS Heat Shrink Bullet Connectors AWG 22-10 creates insulated quick-disconnect joints with a mixed assortment of male and female bullet terminals. The red, blue, and yellow connectors cover AWG 22-10 wiring for compatible vehicle, boat, motorcycle, trailer, and equipment circuits.
| Connector Type | AWG | Color | Pack Quantity | Material/Sealing | Application |
|---|---|---|---|---|---|
| Male and female bullet connectors | 22-16 | Red | 220PCS mixed kit | Tinned copper / adhesive-lined heat shrink | Small accessories and control wiring |
| Male and female bullet connectors | 16-14 | Blue | 220PCS mixed kit | Tinned copper / adhesive-lined heat shrink | Automotive, marine, and equipment wiring |
| Male and female bullet connectors | 12-10 | Yellow | 220PCS mixed kit | Tinned copper / adhesive-lined heat shrink | Higher-current accessory wiring |
Use this kit for compatible quick-disconnect connections in automotive, marine, motorcycle, trailer, outdoor-equipment, and workshop wiring. The adhesive-lined heat-shrink sleeve helps insulate and seal a correctly crimped joint. Do not use a connector outside its listed conductor range, circuit rating, or required terminal standard.
Match the stripped conductor to the listed AWG range and color: red for AWG 22-16, blue for AWG 16-14, and yellow for AWG 12-10. Then confirm that the male and female bullet terminals are the correct mating pair for the equipment. Stud size does not apply to bullet connectors.
Do not use an open flame or continue heating after the sleeve has fully recovered.
Choose the connector by the conductor gauge and the required male or female bullet type. Use red for AWG 22-16, blue for AWG 16-14, and yellow for AWG 12-10, then verify the circuit and equipment requirements.
Use a male bullet with its compatible female bullet of the same connection system and suitable wire range. Bullet connectors do not use a stud size; stud size applies to ring, fork, and similar terminals.
Heat-shrink insulation is useful where a correctly crimped connection needs added insulation, strain support, and moisture resistance, such as vehicle, marine, trailer, and outdoor-equipment wiring. It does not replace correct conductor sizing or crimping.

Haisstronica’s bullet connectors are engineered so that frequent disconnects never limit the flexibility of your circuit. Each bullet connector is designed for a seamless, snap-together fit, allowing wiring bullet connectors to form a reliable electrical path that is as easy to manage as it is to install. Whether you are a professional technician or a home DIYer, this bullet wire connector system provides the ultimate modular convenience for projects that require quick-release efficiency.
Around the high-purity copper core, a thick 3:1 heat-shrink sleeve turns every connection into a hermetically sealed joint. After the snap-fit is secured, heating the electrical bullet connectors triggers the adhesive-lined tubing to shrink tight, creating a waterproof and dustproof barrier around every female bullet connectors pair. This advanced insulation ensures your bullet electrical connector joints stay protected against corrosion and moisture, delivering a factory-style finish that thrives in harsh environments.
Inside the barrel, the design ensures that conductor strands stay fully captured and compressed during the crimping process. After selecting the correct size for your gauge, simply seat the wire bullet connector and apply pressure with a professional tool to ensure the perfect amount of force. A quick pull test confirms the rock-solid mechanical bite, ensuring your wire connectors bullet and electrical bullet connector setups remain stable even under heavy vibration or temperature cycling.
Because real-world value matters as much as performance, Haisstronica provides a 220-piece bullet wiring connectors kit to keep your workshop stocked for any electrical challenge. We stand behind every female bullet connector and male terminal with attentive after-sale support and a risk-free guarantee. If any of our bullet connectors ever fall short of expectations, our team is ready to help with sizing or replacements—so your projects stay powered, sealed, and confident for the long term.
