WF820 - Ferrules & Heat Shrink Tubing Kits

The WF820 Ferrules & Heat Shrink Tubing Kit gives installers a clean, reliable way to terminate 8 AWG power and ground wiring in car audio and 12V systems. Each kit includes tin-plated copper ferrules paired with dual-wall heat shrink tubing, ensuring solid mechanical connections that resist corrosion and vibration over time. A straightforward solution for amplifier installs, distribution blocks, and other high-current wiring work.

• 8 AWG compatibility — sized for common amplifier power and ground runs
• Ten pairs included — 10 red and 10 black ferrules per kit
• Tin-plated construction — resists oxidation for long-term conductivity
• 3:1 heat shrink ratio tubing — conforms tightly to wire and connector for a secure, weatherproof seal
• Color-coded — red and black for polarity identification during installation
