Blue Heat Shrinkable Insulated Ring Terminal M4 (100 Pack)
📝 Blue Heat Shrink Ring Terminal M4 (100 Pack)
These blue heat shrink ring terminals are designed for reliable, sealed connections in automotive, campervan, caravan, marine, and off-grid 12v–48v systems.
Built to suit 1.5–2.5mm² cable (AWG 16–14) and featuring an M4 ring size to suit 4mm studs/bolts, they provide a secure, vibration-resistant crimp connection rated up to 27A.
The heat shrink insulation forms a protective seal when heated, delivering superior moisture resistance, strain relief, and long-term durability compared to standard vinyl or nylon terminals.
⭐ 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 environments.
• Improved vibration resistance – ideal for touring and mobile setups.
• Secure crimp connection – ensures consistent electrical performance.
⚙️ Functionality
After crimping with a suitable ratchet crimp tool, apply heat to shrink the insulation around the cable. The sleeve forms a tight seal around the insulation, helping protect against moisture, dust, and corrosion.
Perfect for fuse blocks, solar wiring, DC distribution systems, and vehicle electrical upgrades.
