HellermannTyton HIS-3 Guaina termorestringente 3:1, 3 mm, nera, 20 cm, 10 pezzi (308-30315)

For reliable insulation and strain relief in tight spaces, this HIS-3 heat shrink tubing offers a 3:1 shrink ratio, allowing it to conform to irregular shapes and provide a secure, professional finish. The cross-linked polyolefin material is self-extinguishing and resistant to common fluids, making it suitable for demanding electrical applications.

Highlights

• 3:1 shrink ratio for effective coverage over connectors and splices
• Supplied diameter 3 mm, recovers to 1 mm for snug fit
• Pack of 10 pieces, each 20 cm long
• Operating temperature range -55 °C to 100 °C
• Self-extinguishing material for added safety

In daily use

Cut the tubing to the desired length, slide it over the connection, and apply heat above 90 °C. The tubing shrinks uniformly, providing insulation, mechanical protection, and a clean appearance. Ideal for cable bundling, color coding, and strain relief in electronics and automotive wiring.
