Key Features & Benefits
- Precision Fit for 12-10 AWG Wiring & M6/M8 Studs
The 3.3mm wire entry is designed to create a tight, moisture-proof seal around 12 AWG to 10 AWG cables. The cap options (11mm and 15mm ID) fit securely over standard M6 (1/4″) and M8 (5/16″) studs found on alternators and distribution blocks, ensuring a stable connection without slipping.
- High-Temp Flame Retardant Silicone Material
The flame-retardant silicone construction provides excellent thermal stability with a working temperature range of -40°C to +230°C. This durable material resists melting or cracking in high-heat engine bays and meets strict safety standards for electrical insulation, unlike standard PVC or rubber covers.
- Total Corrosion & Short Circuit Prevention
The fully enclosed design acts as a robust barrier against dust, oil, moisture, and accidental contact. These insulating boots effectively prevent arc-over and corrosion buildup on the terminal stud and crimp lug, significantly extending the lifespan of electrical systems.
- Enhanced Elasticity & Pull-Tab Design
The soft silicone body offers superior elasticity compared to rigid plastic caps, allowing for easy installation over crimped lugs. Models L3.3-15-51.8 and L3.3-15-59 feature integrated pull-tabs (grips), making removal for maintenance quick and effortless, even in tight spaces.
- Color-Coded for Safety & Identification
The industry-standard Red and Black color options allow for immediate visual identification of Positive (+) and Negative (-) polarity. This color coding is essential for preventing reverse polarity mistakes during installation and maintenance in automotive and marine applications.
