Unique-Bargains Heat Shrink Tubing 120mm Dia 191mm Flat Width 2:1 Ratio 1m Black

Heat-shrink tube for large cables

This black heat-shrink tubing has a 120 mm diameter before shrinking and a 191 mm flat width at a 2:1 shrink ratio. The one-metre length suits electricians and installers insulating thick cable bundles or conduit. It carries a 1000 V rating and operates from -55 °C to +105 °C.

Fits over oversized bundles and shrinks tight

Slide the sleeve over the prepared joint or harness, then apply heat until it contracts to half its original diameter. The material provides electrical insulation, corrosion resistance, high-temperature resistance and waterproof protection. No adhesive liner is mentioned, so mechanical retention or separate sealant may be needed for critical joints.

Replaces tape or smaller tubing on big conductors

Use this instead of wrapping multiple layers of electrical tape or stacking undersized tubing on large feeder cables. The jump is worth it when a single-piece cover must survive 105 °C continuous temperature and 1000 V stress without splitting. It is not for buyers needing adhesive-lined seals or diameters above 120 mm.
