PRO POWER HS500 Series 3:1 Heat Shrink Tubing Black - 25.4mm 2m
Professional 3:1 ratio heat shrink tubing. Flame-retardant, UL224 approved. For industrial, electronic & DIY wire insulation and protection.
PRO POWER HS500 Series 3:1 Heat Shrink Tubing is a professional-grade, flexible insulating solution manufactured from thermally stabilised, flame-retardant polyolefin (PO). Its primary function is to provide robust, long-lasting protection for wiring, connections, and components across a wide array of electrical and electronic applications. Engineered for ease of use, this tubing becomes highly flexible when heated, conforming smoothly to irregular shapes and providing a tight, waterproof seal that guards against moisture, corrosion, abrasion, and short circuits.
A key feature of this heat shrink is its 3:1 shrink ratio, meaning the supplied tubing diameter reduces to one-third of its original size when heated. This high ratio allows for a secure fit over a broader range of wire gauges and terminal sizes, ensuring a reliable, strain-relieving finish. It has a low minimum shrink temperature of just 70°C, making it safe to use on temperature-sensitive components without risk of damage. Once shrunk, it offers excellent performance within an operating temperature range of -55°C to 125°C and achieves full recovery at 120°C.
The tubing provides outstanding mechanical strength and electrical insulation properties, enhancing the safety and durability of any electrical assembly. It meets the stringent Sony SS-00259 standard for environmental management and is UL224 approved, signifying its compliance with recognised safety benchmarks for electrical insulating tubing. The black colour offers a professional, discreet appearance suitable for industrial, commercial, and DIY projects.
Ideal Applications
This versatile heat shrink tubing is perfect for insulating solder joints, providing cable strain relief, bundling wires, creating waterproof seals, and colour-coding circuits. Its reliability and performance make it a trusted choice for electricians, engineers, electronics hobbyists, and maintenance teams.
