1" 2:1 Heat Shrink Tubing | Black | 100' Spool | HST1BK100

Engineered from cross-linked polyolefin, this 1-inch heat shrink tubing delivers professional-grade insulation and mechanical protection with a 2:1 shrink ratio that reduces diameter to 0.5 inches. The 100-foot spool features flame-retardant construction meeting UL 224 standards, UV and chemical resistance for demanding environments, and maintains operational integrity across -55°C to +125°C. Rated for 600V applications with RoHS and CSA certification, it provides a clean, uniform finish ideal for cable bundling, splice protection, and connector insulation in industrial, automotive, and electrical installations.

Features
High Shrink Ratio: 2:1 ratio allows the tubing to shrink to 50% of its original diameter for a secure fit.
Flame Retardant: Meets UL 224 standards for superior fire safety and reliability.
UV & Chemical Resistant: Durable polyolefin construction protects against sunlight exposure and common automotive fluids.
Flexible Application: Easily conforms to irregular shapes and sharp objects without splitting or cold-flowing.
Professional Finish: Solid black, non-printed surface ensures a clean, professional look for wire bundling and identification.
