Express Sleeve Thermo 1in - 1-1/2in x 12ft

The Express Sleeve Thermo 1in - 1-1/2in x 12ft is a marine-grade heat shield sleeve designed for anglers and boaters who demand engine protection in high-performance or compact installations. Whether you're running a center console, cabin cruiser, or performance fishing boat, engine heat can damage critical fuel lines, wiring, and nearby components in tight engine compartments.

This expandable sleeve wraps around hoses and cables to reflect radiant heat away from sensitive equipment, keeping your boat's systems running reliably through long days on the water without costly downtime or heat-related failures. Built by THERMO-TEC, a trusted manufacturer in thermal management solutions, this sleeve features a braided construction that accommodates hoses ranging from 1 inch to 1-1/2 inches in diameter, making it versatile across most marine applications.

The 12-foot length gives you plenty of coverage for exhaust risers, fuel lines, or bundled wiring runs without requiring multiple pieces or splicing. The reflective material actively reduces surface temperatures around protected hoses by deflecting engine heat, which extends hose life and prevents fuel line degradation—critical in saltwater environments where heat and corrosion work together to compromise equipment integrity.
