Black 30FT Heat-Shrink Braided Sleeve 2:1 — 1-1/8" (29mm) to 9/16" | Polyolefin + Polyester

2:1 ratio black braided heat-shrink sleeving, 30FT length. Designed to shrink from an initial inner diameter of 1-1/8" (29mm) down to 9/16" while delivering durable protection for wire bundles and hoses. Construction: Polyolefin + Polyester. Operating temperature range: -40°F to 257°F. Shrink activation temperature: 230°F~365°F (110℃~185℃). Key benefits: abrasion-resistant outer braid protects cables from wear; reduces noise and vibration transmitted by hoses and pipes; resists heat and moisture; self-extinguishing for added safety; tear-resistant and maintains bundled wiring neatness. Also provides UV resistance and helps prevent corrosion and discoloration caused by rust. Typical applications: automotive hoses and irregular-shaped tubing, automotive air conditioning lines, rubber and soft hoses, plastic hoses, wire harnesses, and general electrical wire organization. Flexible design makes it easy to fit over uneven or awkward shapes and offers long-lasting protection against abrasion. Notes: Actual product color may vary slightly due to photography and monitor differences. When two or more lengths are ordered we normally join the pieces and ship them together as a single continuous length.
