The GBC heatshrink eyelet terminal (MPN 18.3923.60) is a ring-tongue connector with a heat-shrink PVC sleeve that contracts 3:1 to seal the wire entry point against moisture ingress. Tin-plated copper construction and PVC insulation resist condensation, salt water, battery acid, motor oil, and isopropyl alcohol.

Compatible with cable cross-sections of 0.5–1.5 mm² (AWG 22–16), this terminal mounts to M8 fasteners via a 8.4mm screw hole. Its 12mm external diameter and 34.7mm length are sized for M8 bolt heads on chassis earth points, battery terminals, and similar heavy-duty connections. Supplied in packs of 10, colour-coded red.

Key Features

• Heat-shrink PVC sleeve with 3:1 shrinkage ratio creates a watertight seal at the wire entry
• Tin-plated copper contact resists corrosion and maintains conductivity in harsh environments
• M8 screw hole (Φ8.4mm) fits large chassis fasteners, battery terminals, and earthing studs
• Red colour coding matches the 0.5–1.5 mm² / AWG 22–16 cable convention
• Rated to 300V maximum voltage

Product Benefits

• Sealed entry protects the crimp joint from salt water, condensation, and chemical solvents
• Resistance to gasoline, battery acid, and motor oil makes it dependable in under-bonnet wiring
• Built-in heat-shrink sleeve eliminates the need to slide on a separate shrink tube before crimping
• M8 sizing serves the largest common automotive and marine fastener size in one terminal
• Pack of 10 provides enough terminals for a full circuit repair or harness modification
