What exactly comes in the kit and why does it matter?

The Filluck kit packs 945 pieces to cover routine connector repair and maintenance. You get 525 pin terminals across 21 sizes, 400 waterproof plugs, an 18-pin extraction needle, tweezers for handling small parts, and a ratchet crimping tool, all in a clear, labeled box.

• 525 pins in 21 diameters for precise fit to pin housings
• 400 rubber seals to restore waterproofing on multi-pin plugs
• Extraction needle and tweezers for safe removal and installation
• Ratchet crimping tool sized for 22–16 AWG crimps with consistent pressure

How do the materials and construction affect performance?

Filluck terminals are made from galvanized brass to provide stable electrical contact and corrosion resistance. The matched rubber seals create a tight, insulating barrier to reduce moisture ingress and protect connections from oils and fluids common in vehicles.

• Galvanized brass pins for reliable conductivity and longevity
• Rubber seals sized to match pin diameters for airtight protection
• Crimp profiles designed to form secure mechanical and electrical bonds

Which wire types and applications are supported by this kit?

The terminals cover common automotive and electronics wire gauges, so you can repair engine bay harnesses, sensors, lighting circuits, household appliances and hobby electronics. The variety of pin diameters means you can reuse existing housings or rebuild connectors to original-style assemblies.

• Compatible with 22–16 AWG wires typically used in cars and electronics
• Useful for sensors, lights, ECU connectors, and small appliance wiring
• Supports both male and female mating contacts for full harness repair

How easy is it to use the kit for repairs and assembly?

The kit is built for straightforward installation: the ratchet crimping tool provides consistent pressure for repeatable crimps, while the extractor and tweezers help seat and remove pins without damaging housings. Labeled compartments speed up part selection so you can work faster and with fewer errors.

• Ratchet crimper ensures uniform crimps across many terminals
• Needle extractor removes pins without deforming connector bodies
• Clear, labeled storage box keeps parts organized for quick access
