Ancor 312599 Marine Grade Heat Shrink Ring Terminals 12-10 AWG 5/16" Stud 100-Pack

The Ancor 312599 Marine Grade Heat Shrink Ring Terminals deliver professional-grade electrical connections engineered specifically for harsh marine environments. Designed for 12-10 AWG wire and 5/16" fasteners, these terminals combine superior materials with heat-activated sealing technology to provide reliable, long-lasting performance on boats and marine equipment.

Advanced Heat Shrink Technology:

• Cross-linked polyolefin tubing resists burning and outperforms standard PVC in strength and durability
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and UV sunlight
• Industry-leading shrink ratio reduces to 1/3 original size for tight, secure fit
• Activates at 257°F (125°C) for reliable heat shrinking
• Provides superior strain relief and vibration resistance

Marine-Grade Construction:

• Pure copper conductor for maximum current flow and conductivity
• Tinned copper construction resists corrosion in saltwater environments
• Brazed seam ensures maximum mechanical strength
• Nylon insulator offers excellent resistance to sunlight, water, oil, chemicals, and cut-through damage
• UL Listed and CSA Recognized for quality assurance

Specifications:

• Wire gauge: 12-10 AWG
• Stud size: 5/16" (8mm)
• Operating temperature range: -40°C to 110°C
• Color: Yellow for easy gauge identification
• Quantity: 100 terminals per pack

These heat shrink ring terminals are ideal for critical marine electrical connections where moisture protection and reliability are essential. The combination of tinned copper, adhesive-lined heat shrink, and nylon insulation makes them perfect for boat wiring, marine electronics, battery connections, and any application exposed to water, salt spray, or extreme conditions.
