Blue Heat Shrinkable Insulated Ring Terminal M12 (100 Pack)
📝 Blue Heat Shrink Ring Terminal M12 (100 Pack)
These blue heat shrink ring terminals are built for sealed, vibration-resistant electrical connections in campervan, caravan, marine, automotive, and off-grid 12v–48v systems.
Designed to suit 1.5–2.5mm² cable (AWG 16–14) with an M12 ring size to fit 12mm studs/bolts, they provide a secure crimp connection rated up to 27A.
Once heated, the insulation shrinks tightly around the cable, forming a protective seal that improves strain relief and resists moisture, dust, and corrosion — making them ideal for mobile and harsh environments.
⭐ Essential Benefits
• Heat shrink insulation – creates a sealed, moisture-resistant connection.
• 27A max current rating – ideal for medium-duty DC circuits.
• 105°C temperature rating – suitable for demanding installations.
• Superior vibration resistance – perfect for touring and marine setups.
• Secure crimp connection – delivers 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 improves durability and connection stability.
These are ideal for fuse blocks, DC distribution, solar inputs, accessory circuits, and general 12v wiring upgrades.
