4 Simple Steps To Seamless Wire Connections
1
Prep Your Cables
Strip your wire insulation 1/3" on both wire ends & twist the strands together.
2
Insert & Connect
Use SolderGrip Sleeve to connect the wires together with the right connector size.
3
Heat To Seal
Apply heat with a heat gun, lighter or blow dryer while continuously rotating the wire.
4
Enjoy Durable Connection
Enjoy your secured and waterproof wire connection!
Sealed For Good
Inside every connector sits a low-temperature solder ring, flanked by two rings of waterproof hot-melt adhesive. Apply heat and the solder melts straight into the copper strands — a real metal bond, not a mechanical pinch that works loose.
Seconds later the adhesive flows and the sleeve shrinks tight around the insulation. Water, dust, salt spray and road vibration stay outside where they belong. IP67 rated, engine bay to boat deck.
Sized By Color
Four color-coded sleeves cover 26–10 AWG, so you match the connector to the wire at a glance — white for 26–24, red for 22–18, blue for 16–14, yellow for 12–10. No guesswork, no test-fitting, no splice that's a half-size too loose.
Every box arrives pre-sorted in the ratio real jobs actually use: heavy on the mid-gauges you reach for daily, with the fine and heavy sizes there when you need them

Almost always the same reason: the wrong solder alloy. Cheap kits use a low-grade mix that won't flow before the sleeve burns. SolderGrip's TriSeal ring is calibrated to flow at exactly 280°F — you watch it happen through the transparent tube. If it didn't flow last time, that kit was defective by design. Ours isn't.
That's exactly what IP67 means — tested to withstand submersion. The adhesive bands on both ends seal against moisture migration down the wire itself. Boat owners are our highest repeat-purchase segment.
You can, but a heat gun gives even, controlled heat and a consistent result every time. The heat gun add-on in your cart saves $31.99 vs buying separately — it's exactly what we use in every demo.
White: 26–24 AWG · Red: 22–16 AWG · Blue: 16–12 AWG · Yellow: 12–10 AWG. Color coded — match the connector to your wire in under 3 seconds.
