HellermannTyton HIS-3 Heat Shrink Tubing 3:1, 3 mm, Black, 20 cm, 10 Pieces (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
