4:1 Waterproof Dual Wall Heat Shrink Tubing With Glue
E-FLEX® Glue Lined Heat Shrink is a high-performance, dual-wall tubing engineered for superior environmental sealing. It features an irradiated polyolefin outer layer and a heat-activated adhesive liner. Upon heating, the adhesive melts and flows to provide a robust seal against moisture, corrosion, and mechanical stress. The exceptional 4:1 shrink ratio allows for a precise fit over oversized or irregular shapes, ensuring a tight, durable shield.
What's Special about Glue Lined Heat Shrink Tubing?
- Superior coverage for irregular shapes; simplifies inventory by covering a wider range of component sizes.
- Adhesive lining flows to block moisture and contaminants, preventing cable corrosion.
- VW-1 flammability rated with ≥15KV/mm dielectric strength for guaranteed electrical safety.
- Maintains performance from -55℃~+125℃ in harsh operational environments.
