Description
The GBC 18.3923.30 is a heat-shrinkable eyelet terminal for cables in the 0.5–1.5 mm² range (AWG 22–16). Its 3:1 shrinkage ratio creates a tight, sealed connection after heat application, protecting the joint from condensation, salt water, corrosion, and solvents including isopropyl alcohol, gasoline, battery acid, and motor oil.
The terminal is recommended for any installation at risk of water contact — automotive wiring, outdoor runs, marine electronics, and similar environments. The M4 bolt hole (Φ4.3mm) and PVC/tin-plated copper construction are the same as the standard pre-insulated range, with the addition of the heat-shrink sealing step. Red colour coding identifies the 0.5–1.5 mm² range. Each pack contains 10 pieces.
Key Features
- Heat-shrinkable sleeve with 3:1 shrinkage ratio for a sealed, watertight termination
- Protects against condensation, salt water, corrosion, isopropyl alcohol, gasoline, battery acid, and motor oil
- Designed for cable cross-sections 0.5–1.5 mm² (AWG 22–16)
- M4 screw type with Φ4.3mm hole diameter
- Red PVC/heat-shrink sleeve and tin-plated copper contact
Product Benefits
- Sealed termination prevents moisture ingress that would corrode a standard crimp joint over time
- 3:1 shrink ratio grips the cable jacket for additional strain relief beyond the crimp
- Solvent resistance makes these terminals reliable in engine bays, bilges, and industrial outdoor enclosures
- 300V rating and tin-plated copper contact suit low-voltage automotive and marine circuits
- Red colour coding identifies the 0.5–1.5 mm² range even after the sleeve has shrunk
