Gorffy 300PCS Wire Connectors Kit, Male and Female Spade Connectors, 17 Types Electrical Connector Kit 0.5-6.0mm², Insulated Terminal Connector, Includes Spade Ring Fork Wire Terminal

Overview

I keep a few connector kits on hand for bench work and mobile installs, and the Gorffy kit has quietly become the one I reach for most when I need everyday spades, rings, and forks. It’s a 300-piece assortment covering the common red/blue/yellow ranges (AWG 22–10) with male and female spades in 2.8 mm, 4.8 mm, and 6.3 mm, plus a spread of ring and fork terminals. The appeal here isn’t anything exotic—no heat-shrink barrels or marine-grade adhesive sleeves—just a well-rounded, color-coded set that gets robust, solder-free connections made quickly.

What’s in the box

The kit is organized into a compact, sturdy organizer with individual compartments for each terminal type and size. I appreciate that the layout mirrors how I work: small 2.8 mm spades for switch panels and compact modules; 4.8 mm and 6.3 mm spades for standard automotive tabs; and the expected ring and fork terminals for grounding and bus connections. The color coding aligns with the usual wire ranges:

• Red: 0.5–1.5 mm² (AWG 22–16)
• Blue: 1.5–2.5 mm² (AWG 16–14)
• Yellow: 2.5–6.0 mm² (AWG 12–10)

Gorffy uses tin-plated brass contacts with nylon insulation. The barrels sit squarely inside the sleeves, which makes placement in the crimper straightforward.

Build quality and materials

For a value-oriented kit, the materials are better than I expected. The tin plating is even and takes a crimp cleanly; I didn’t see flashing or burrs on the spade tongues that can otherwise snag during mating. The nylon jackets are clearer and stiffer than PVC, which helps with visibility of the wire insertion and barrel alignment.

That said, stiffness can be a double-edged sword. With a non-ratcheting crimper and an aggressive squeeze, I managed to crack two red sleeves (both 2.8 mm females) during my first session. Switching to a proper ratcheting crimper with the insulated-terminal die eliminated the issue, and I didn’t crack another sleeve across roughly 50 additional crimps. If your only tool is a stamped plier-style crimper, be gentle and use the right cavity; over-compression will split these.

The barrel wall thickness is on par with typical general-purpose connectors but a notch thinner than premium terminals used in high-vibration or under-hood environments. For routine 12 V work, they’re fine. For harsh environments (engine bays, marine bilges), I’d step up to a heat-shrink or tinned copper marine-grade terminal.

In use: crimping and pull strength

I tested with stranded copper in three sizes: 18 AWG (lamp cord), 16 AWG (automotive primary), and 12 AWG (amplifier power runs). Using a ratcheting crimper:

• Red terminals on 18 AWG and 16 AWG seated easily with a visible double-dimple in the barrel and no jacket damage.
• Blue terminals on 16 AWG felt most secure; on the thicker side of 14 AWG they required a careful squeeze but still formed a solid indent.
• Yellow terminals on 12 AWG produced a firm mechanical lock without cutting strands.

My quick-and-dirty pull tests (hand tug and a luggage scale) showed failure consistently above what I’d expect for generic connectors. Most crimps held to the point where the wire strands stretched or slipped at 20–35 lb depending on size and terminal type. For spades, the crimp held; if anything gave way, it was the spade’s mating friction before the crimp itself.

Electrical performance was uneventful—in the best way. Voltage drop across a ring-lug crimp with a 12-inch loop of 16 AWG under a 10 A load was essentially in the noise compared to a soldered counterpart. The tin plating and tight barrel compression provide low-resistance contact when properly crimped.

Fit and compatibility

The fit of the spades was pleasantly snug:

• 2.8 mm (approx. 0.110 in) females mated cleanly to blade tabs on compact rocker switches without having to “tune” the spring tension.
• 4.8 mm (0.187 in) and 6.3 mm (0.250 in) females offered a firm push-on with positive retention and no deformation after a few test cycles.

If you need to repeatedly connect and disconnect the same pair, be aware that these aren’t designed for endless cycles. After a dozen mate/demate operations on one 6.3 mm pair, retention loosened slightly, still serviceable but less “clicky.” That’s normal for this class of terminal; if quick-disconnect longevity matters, look for higher-cycle-rated connectors.

Ring and fork assortments cover light-duty stud sizes commonly found in relay blocks and small bus bars. You won’t find heavy battery lugs or large-diameter rings in this kit, and that’s appropriate given the wire size range tops out at 10 AWG.

Organization and labeling

Simple but effective. Each compartment holds a single type/size, and the translucent sleeves make it easy to confirm you’ve grabbed the right piece. The box latch is solid and survived a few tosses into a van bin without spilling contents into neighboring compartments. It’s not a field-service Pelican vault, but it does the job.

Limitations and caveats

• Sleeve brittleness with improper tooling: Use an insulated-terminal die and avoid over-crimping. These nylon sleeves don’t forgive flattened, slip-prone jaws.
• Barrel thickness: Adequate for general use, but not the tank-like feel of industrial-grade terminals.
• No heat-shrink or adhesive lining: If you’re working in wet or corrosive environments, pair these with external heat-shrink or step up to sealed terminals.
• Not a “complete everything” kit: You get spades, rings, and forks in useful sizes, but no butt splices or specialty terminals.

Who it’s for

• DIYers and technicians doing 12 V and low-voltage wiring in vehicles, motorcycles, trailers, and household gadgets.
• Anyone setting up switch panels, relays, LED lighting, or accessory harnesses who needs common spade sizes and light-duty ring/fork options.
• Beginners learning proper crimp technique—color coding, visible barrel alignment, and predictable results make this a friendly starter kit.

If you’re outfitting a marine engine bay or need mission-critical reliability in high heat and vibration, treat this as a secondary kit and rely on sealed, heavy-duty terminals for those circuits.

Value

For the piece count and spread of sizes, the Gorffy kit is strong value. I didn’t encounter out-of-spec spade widths or deformed barrels—the kind of QC hiccups that waste time and confidence. The ratio of male/female spades to rings/forks is sensible for general use, and the box is durable enough to live in a tool bag without turning into a rainbow soup.

Tips for best results

• Use a ratcheting crimper with the correct insulated-terminal die. Match the die color to the terminal color.
• Strip to the barrel length and ensure copper strands are fully inside the barrel; don’t crimp on insulation.
• Give each crimp a firm tug test. If it slips, cut and redo—it’s cheaper than troubleshooting later.
• Avoid soldering after crimping; solder wicks and can create a rigid failure point at the barrel exit.
• For damp environments, add heat-shrink over the nylon sleeve and a dab of dielectric grease on spade pairs.

Final recommendation

I recommend the Gorffy kit as a dependable, good-value assortment for everyday electrical work. It covers the essentials—common spade sizes plus ring and fork terminals—using materials that crimp cleanly and hold up well when you use the right tool. The nylon sleeves are on the stiff side and can crack with poor technique, and this isn’t the set for extreme environments or heavy battery cables. But for automotive accessories, motorcycle wiring, trailers, and household projects where you need quick, solder-free connections, it’s exactly the kind of organized, “grab-and-go” kit I like to keep near the top of the toolbox.
