The Pico Wiring 8263A is a professional-grade waterproof heat shrink tubing designed for reliable electrical connections in automotive, marine, and powersports applications. This 1/2-inch diameter tubing features a vibrant red color for easy circuit identification and includes a heat-activated adhesive inner lining that creates a watertight seal when heated.

Key Features:

• 1/2-inch (12.7mm) diameter accommodates medium-gauge wire bundles and connectors
• Dual-wall construction with adhesive-lined interior for superior moisture protection
• Red color coding for positive circuits and easy wire identification
• 3:1 shrink ratio provides secure fit over irregular shapes and connections
• Heat-activated sealant melts and flows to create waterproof barrier
• Resistant to automotive fluids, UV exposure, and temperature extremes
• Operating temperature range: -40°F to 257°F (-40°C to 125°C)

Ideal for marine wiring, trailer connections, under-hood applications, and any environment where moisture protection is critical. Simply slide the tubing over your connection and apply heat with a heat gun to shrink and seal. The adhesive lining ensures a permanent, waterproof bond that protects against corrosion and electrical failures.
