HellermannTyton Heat Shrink Tubing Black 8 mm Sleeve Diameter 50 mm Length 4:1 Ratio TG40

HellermannTyton TG40 Heat Shrink Tubing, model TG40, is a semi-rigid black polyolefin sleeve with an 8 mm sleeve diameter and 50 mm length, designed for reliable electrical insulation and mechanical protection in demanding environments. It features a 4:1 shrink ratio, shrinking to a 1.65 mm diameter upon heating, making it suitable for covering wire joints, terminals, and harnesses.

This heat shrink tubing operates safely across a wide temperature range of -55°C to +125°C, with shrink activation beginning at 110°C to ensure predictable recovery. Its flame-retardant and self-extinguishing construction reduces fire propagation risk, while its capability to withstand AC2500V/60s without electrical breakdown provides outstanding safety in high-voltage applications.

The inner adhesive lining melts during shrinking to seal against moisture ingress and enhance strain relief at connections, improving durability and reliability. The tubing is resistant to chemicals including acids, alkalis, oils, and fuels, extending its service life in harsh environments. It meets RoHS compliance and conforms to UL224 600V 125°C Class 1 and SAE‑AMS‑DTL 23053/5 flammability standards.

Typical dielectric strength is about 11.9 kV/mm measured per IEC 243, delivering strong electrical insulation suitable for high-voltage testing and industrial use.

Storage recommendations include keeping the tubing below 40°C away from direct sunlight to maintain performance, which provides a shelf life of five years. This product is widely used for insulating wire terminations in harness assemblies, protecting cable splices in automation equipment, sleeving wiring in electrical panels and junction boxes, and offering abrasion protection for mechanical assemblies.

This heat shrink tubing offers excellent thermal, chemical, and electrical protection. It is suitable for industrial, electrical, automation, and manufacturing applications. The adhesive-lined polyolefin sleeve ensures moisture sealing and strain relief.

It provides a flame-retardant, self-extinguishing solution for fire safety. RoHS compliant and meets international electrical and flammability standards. Wide temperature operating range from minus 55°C to 125°C. High dielectric strength supports high-voltage insulation needs.

Ideal for wire harness assemblies and cable joint protection. Explore more products in Heat Shrink Tubing for your electrical and industrial applications at EnvMart.
