HELLERMANNTYTON set guaine termorestringenti HIS-3, rapporto di restringimento 3:1, colori vari, 100 pezzi, lunghezza 200 mm 308-31214

Heat shrink tubing set with a 3:1 shrink ratio, providing a secure, insulating seal for electrical connections. The set includes 100 pieces in assorted colours, each 200 mm long, with diameters from 1.5 mm to 18 mm before shrinking. Made from cross-linked polyolefin, the tubing shrinks at +90 °C and operates from -55 °C to +125 °C.

Advantages

Cross-linked polyolefin construction delivers reliable insulation and strain relief. The 3:1 shrink ratio allows the tubing to conform to irregular shapes, while the assortment of colours aids in wire identification.

Suitable for

• Insulating electrical splices and terminations
• Bundling wires and cables
