Fultyme RV 590-5005 Dual Wall Heat Shrink Tubing 3/16" x 48" Black

The Fultyme RV 590-5005 is a professional-grade dual wall heat shrink tubing engineered for automotive, marine, RV, and truck electrical applications. This 48-inch length of 3/16-inch diameter tubing delivers reliable, long-lasting protection for wire connections, splices, and terminals in the harshest environments.

Key Features:

• Dual wall construction — flexible polyolefin outer layer with a heat-activated adhesive inner liner for a secure, watertight bond
• 3/16" (4.8mm) diameter x 48" length — generous length for multiple repairs or larger projects
• 3:1 shrink ratio — accommodates a wide range of wire gauges and connector sizes
• Moisture and weatherproof seal — adhesive inner wall melts upon heating to block moisture, salt spray, chemicals, and abrasion
• Flame retardant material — meets safety standards for automotive and marine electrical use
• Black color — professional appearance with added UV resistance for outdoor and exposed installations

Installing the 590-5005 is straightforward: slide the tubing over your connection or splice, then apply heat with a heat gun or torch. The outer layer shrinks while the adhesive inner liner flows and seals around the wire, creating a durable, weatherproof connection. Ideal for repairing wiring harnesses, protecting splices, and building professional-quality electrical connections in RVs, boats, trucks, and outdoor equipment.
