Lixternum 950-Piece Pin Connector Kit — Copper Pins, Waterproof Seals & SN-48B Crimper

Lixternum’s 950-piece connector kit supplies a full set of copper male and female pins, rubber seals, a crimping plier and removal tools to repair or build durable, sealed automotive and electronics wire connections.

This complete assortment bundles the most commonly used pin diameters with matching waterproof plugs and the tools you need to crimp, inspect and remove terminals without replacing entire housings. Everything is organized in a transparent, labeled storage box so you can identify sizes quickly and carry the kit to the workshop, garage, or job site.

What sizes and parts are included, and how will they cover varied jobs?

The kit contains 950 pieces: 550 copper terminal pins across 28 styles, 400 rubber waterproof plugs, an SN-48B crimping plier, 18 needle extractors, tweezers, and a clear compartment box. Sizes range from 1.0 mm up to 3.5 mm pin diameters, covering typical automotive and small-electronics wiring.

• Pin diameters: 1 / 1.5 / 1.8 / 2.2 / 2.3 / 2.8 / 3.5 mm
• 550 terminals in multiple male/female formats for polarity and device compatibility
• 400 rubber seals to create moisture-resistant connections
• SN-48B crimp plier and removal tools for installation and service

How do the materials and seals affect electrical reliability?

Terminals are stamped from quality copper for solid conductivity and dimensional stability; rubber sealing rings provide insulation and help keep out oil, brake fluid and moisture. Together they produce connections that maintain low resistance while resisting environmental contaminants.

• Copper pins for consistent electrical contact and corrosion resistance when properly installed
• Rubber plugs that compress around wires to reduce ingress of liquids and dirt
• Crimped joints form a mechanically stable, low-resistance connection when done with the included plier

Can this kit replace damaged connectors without soldering new housings?

Yes — the assortment is designed so you can replace individual pins and seals inside existing multi-pin housings, restoring original fit and function without cutting housings or splicing in new plugs. Properly matched pins and seals reestablish the factory-style interface.

• Match pin diameter and gender to the original terminal for a snug fit
• Use the needle removers to extract old pins without damaging the housing latch
• Crimp or solder pins depending on preference and the application’s vibration or environmental needs

What tools are provided and how do they make installation easier?

The SN-48B crimping plier included is sized for the kit’s terminal range and helps form reliable crimps quickly; tweezers and needle extractors simplify pin removal and placement inside tight housings. The transparent, labeled storage tray keeps parts sorted for fast selection.

• SN-48B crimper tailored to the kit’s pin sizes for consistent crimps
• 18 needle extractors and tweezers to remove or seat terminals without breaking plastic housings
• Clear, compartmented box that prevents loss and speeds part identification

Who this kit is for: technicians, mechanics, electricians, and DIYers who service cars, motorcycles, marine equipment, small aircraft electronics or household appliances will find this kit covers the most common terminal needs. It’s also useful for restoration projects and custom wiring harness work where maintaining original connector housings matters. If you need a single, portable set that provides multiple pin sizes, seals and the basic tools to crimp and extract terminals, this Lixternum kit is tailored for that purpose.
