Ancor 302648 Heat Shrink Tubing 3/16" x 48" Red Marine Grade

Ancor's marine-grade heat shrink tubing provides superior protection for electrical connections in harsh marine environments. This 3/16" diameter, 48" length red tubing features cross-linked polyolefin construction with a heat-activated adhesive lining that creates watertight, corrosion-resistant seals.

Key Features:

• Cross-linked polyolefin construction - stronger and more durable than PVC tubing, won't burn like PVC
• Heat-activated adhesive lining creates an impervious seal against salt water, oil, acids, and sunlight
• 3:1 shrink ratio - shrinks to one-third of original diameter for secure fit
• Provides excellent strain relief for wire connections
• Activates at 257°F (125°C)
• Operating temperature range: -40°F to 230°F (-40°C to 110°C)
• UL 224 listed for quality assurance
• Suitable for 20-12 AWG wire

Installation Tips:

Apply heat gradually using a heat gun or torch, moving the heat source continuously along the length of the tubing to ensure even shrinkage and prevent burning. The adhesive lining will flow and seal as the tubing shrinks, creating a waterproof connection ideal for marine, automotive, and outdoor electrical applications.

Each package includes one 48-inch piece of red heat shrink tubing.
