Phillips Cable STA-DRY Heat Shrink Tubing - Adhesive-Lined Dual-Wall Electrical Insulation

Phillips Cable STA-DRY® Heat Shrink Tubing is a professional-grade, adhesive-lined dual-wall electrical insulation solution trusted by fleet technicians, electrical builders, and powersports professionals across the automotive, commercial vehicle, marine, RV, and off-road industries. Engineered by Phillips Industries — a family-led manufacturer with nearly a century of innovation — the STA-DRY® line goes beyond basic wire insulation to deliver a complete moisture and contamination barrier wherever electrical integrity is critical.

At the heart of the STA-DRY® line is an adhesive-lined, cross-linked polyolefin dual-wall construction that waterproofs and insulates in a single application. When heat is applied, the outer wall shrinks radially while the inner adhesive layer activates, flows into voids, and forms a permanent, conforming, watertight seal around wires, splices, terminals, and connectors — providing protection that standard single-wall tubing simply cannot match.

Key Features:

• Dual-Wall Adhesive-Lined Construction — Cross-linked polyolefin outer shell combined with a heat-activated inner adhesive delivers a tight, conforming seal that bonds securely to surrounding surfaces
• Permanent Watertight Seal — Activated adhesive locks out moisture, road salts, chemicals, and mineral buildup that lead to corrosion and connection failure in demanding environments
• Extended Terminal and Connection Life — Protects terminals and electrical connection points from oxidation, dramatically extending service life wherever exposure to the elements is unavoidable
• Mechanical Strain Relief — Adds reinforcement at high-stress points in wire harnesses and cable assemblies, reducing the risk of wire fatigue and breakage over time
• High Dielectric Strength — Rated for dependable electrical insulation across a broad range of low- and mid-voltage applications
• UV, Abrasion, and Chemical Resistance — The polyolefin outer wall withstands abrasion, UV exposure, temperature extremes, and chemical exposure common in commercial, marine, and powersports environments
• No Special Tools Required — Applied with a standard heat gun — no adhesives, primers, or specialized equipment needed for a clean, professional result
• Broad Application Range — Suitable for primary wire protection, harness assembly, splice insulation, repair work, and general electrical maintenance across a wide variety of equipment and industries

The STA-DRY® Heat Shrink Tubing line is available in multiple configurations to accommodate varying wire gauges, connection types, and job requirements. Select the variant that best fits your application and count on STA-DRY® to deliver the proven sealing performance professionals depend on.
