Twippo Automotive Crimp Terminal Pin Kit 440pcs — 1.5/1.8/2.5/2.8mm Tinned Copper, 22–12 AWG

Twippo 440-piece crimp terminal pin kit supplies a complete set of tinned-copper male and female pins for reliable automotive and low-voltage wiring connections.

This kit groups 440 precision crimp pin terminals across the common 1.5 / 1.8 / 2.5 / 2.8 mm series so you can rebuild or repair a wide range of 12V wiring harnesses. The pins are manufactured from fully tinned copper to resist corrosion and maintain consistent conductivity, and the assortment fits many standard housings used on motorcycles, cars, trucks, boats and garden equipment. Everything is arranged to help professionals and DIYers restore connector performance without hunting down individual sizes.

What sizes and wire gauges are included?

The set covers the typical small-series terminal dimensions used in many automotive and accessory connectors. It is intended to work with most 22–12 AWG automotive wires and common connector shells used in vehicle harnesses.

• Four pin series: 1.5 mm, 1.8 mm, 2.5 mm, 2.8 mm sizes.
• Compatible with 22–12 AWG wiring ranges found on lighting, sensors, and power leads.
• Both male and female crimp pins included for full connector repair.
• 440 pieces total to stock multiple projects or replacements.

How do these pins perform and how are they made?

Each terminal is stamped from copper and plated with tin to improve oxidation resistance and electrical contact. The plated surface and accurate dimensions give dependable electrical continuity while the crimp geometry secures the conductor and insulation when properly crimped.

• 100% tinned copper construction for corrosion resistance and conductivity.
• Precision stamping for consistent fit into connector housings.
• Designed to hold tightly after a proper crimp, reducing intermittent faults.
• Lightweight design that preserves connector alignment and sealing.

Which connectors and applications will these pins work with?

The kit is tailored to general-purpose 12V systems and common automotive connector families. Use them to repair or modify harnesses on vehicles, marine gear, lawn equipment, and small industrial controls where those pin dimensions are specified.

• Motorcycles, cars, trucks, tractors and boats for lighting, sensors and accessories.
• Weatherpack-style and similar sealed or unsealed connector shells when fitted to the correct pin size.
• Hobby electronics and DIY projects requiring robust crimped contacts.
• Field repairs and maintenance where quick terminal replacement is needed.

What do I need to crimp and install these pins correctly?

Good results require the right tools and technique: strip to the proper conductor length, seat the wire in the barrel, and use a matched crimp tool for automotive terminals. After crimping confirm the pin locks securely into the housing and test continuity before reassembly.

• Use a dedicated open-barrel crimp tool sized to the pin series for best mechanical hold.
• Strip the conductor cleanly to the recommended length for the pin type.
• Inspect crimps for proper compression and test with a multimeter if available.
• Replace any pins with visible damage or poor fits to avoid failures.

Who this kit is for: technicians, mechanics, boat owners, hobbyists, and anyone who maintains or customizes 12V wiring will find this Twippo terminal pin assortment useful. It provides a broad set of sizes and both genders of pins so you can repair connectorized wiring, build custom harnesses, or keep a reliable parts stash for field fixes without buying individual terminals.
