HellermannTyton Heat Shrink Tubing 12.7mm 2:1 Black 1.2m

The HellermannTyton 183-24100 is a high-quality, thin-wall heat shrink tubing designed for electrical insulation, mechanical protection, and cable bundling. Made from flexible polyolefin with a 2:1 shrink ratio, it shrinks to half its supplied diameter when heated above +90°C, providing a tight, secure fit around cables, wires, and connectors. This black tubing has a supplied diameter of 12.7 mm and recovers to 6.4 mm, with a length of 1.2 meters per piece. It operates reliably in extreme temperatures from -55°C to +135°C and offers excellent dielectric strength (>20 kV/mm) and tensile strength (>10 MPa). The tubing is UL and CSA approved, RoHS compliant, and meets MIL-DTL-23053/5 Class 1 & 2 standards. Its UV and chemical resistance make it suitable for both indoor and outdoor applications.

Advantages

This heat shrink tubing provides reliable insulation and protection against moisture, abrasion, and mechanical stress. The 2:1 shrink ratio ensures a snug fit without excessive material, while the thin-wall design maintains flexibility. It is self-extinguishing (UL94 V-2) and resistant to common fluids and solvents, making it ideal for demanding environments.

Suitable for

• Electrical insulation of wires and cables
• Mechanical protection for connectors and terminals
• Cable bundling and organization
• Automotive, industrial, and electronic applications
• Outdoor installations requiring UV resistance
