Description
x📝 Yellow Heat Shrink Ring Terminal M12 (100 Pack)
These yellow heat shrink ring terminals are designed for heavy-duty, sealed electrical connections in campervan, caravan, marine, automotive, and off-grid 12v–48v systems.
Built to suit 4–6mm² cable (AWG 12–10) with an M12 ring size to fit 12mm studs/bolts, they provide a secure crimp connection rated up to 48A.
Once heated, the insulation shrinks tightly around the cable, forming a protective seal that improves strain relief and protects against moisture, dust, corrosion, and vibration — ideal for higher-current DC circuits in mobile environments.
<>⭐ Essential Benefits
• Heat shrink insulation – creates a sealed, moisture-resistant connection.
• 48A max current rating – suitable for higher-current DC circuits.
• 105°C temperature rating – built for demanding installations.
• Heavy-duty cable capacity – suits 4–6mm² wiring.
• Secure crimp connection – ensures long-term electrical reliability.
⚙️ Functionality
After crimping with a suitable ratchet crimp tool, apply heat using a heat gun to activate the insulation. The sleeve shrinks tightly around the cable insulation, forming a protective barrier that strengthens the joint and improves durability.
These are ideal for battery feeds, fuse holders, distribution blocks, solar wiring, and higher-load accessory circuits.
