Sky High Car Audio Red Solder Seal Wire Connectors AWG 18-22 150 pc

Clean, reliable splices for small-gauge wiring. These red solder-seal connectors are sized for 18–22 AWG and use a low-temp solder ring plus adhesive-lined heat-shrink to create a strong, waterproof connection—no separate crimp or extra heat-shrink required.

Key Features

• One-step solder & seal: Heat melts the solder and shrinks the tubing while adhesive flows, forming a durable, water-resistant joint.
• Color-coded sizing: Red band = 18–22 AWG for quick ID in the bay.
• Transparent tubing: Lets you see the solder flow for a proper bond.
• Built-in strain relief: Adhesive grips insulation to resist pull-outs and vibration.
• Tool-light install: Just a heat gun or micro-torch—no crimper needed.
• Quantity: 150 pieces (great for shop stock and full rewires)

Ideal Uses

Speaker leads, remote turn-on, LEDs/lighting, sensors, and general 12V accessory wiring in cars, trucks, marine/UTV, and powersports.

Note: For large battery/alternator cables, use proper lugs and heavy-duty crimps.

Quick How-To

1. Strip ~1/4” (6–7 mm).
2. Overlap wire ends inside the sleeve (solder ring centered).
3. Heat from the center outward until solder fully flows and ends seal.
4. Let cool, then perform a light pull test.
