SEMI-RIGID ADHESIVE-LINED HEAT SHRINK TUBING SHRINK RATIO 4:1 BH-BK
- Applications: Semi-rigid adhesive-lined heat shrink tubing specially designed to protect splices and joint of wire harness, and other components against environment damage
- Characteristics: Semi-rigid make it more abrasion resistant component with common tubing,4:1 shrink ratio make it easily to fit a wide range of component, and thicker adhesive coated layer forms effective barrier against fluids and moisture
-
Operating temperature range: Operating temperature: -45℃~+125℃
Minimum shrink temperature: 120℃ - Approvals / Specifications: CE
- Colors: Black, Transparent
