HellermannTyton HIS-3 Heat Shrink Tubing Set 3:1, 1.5 mm/0.5 mm, Transparent, 10 Pieces 308-30164

The HIS-3 set delivers a 3:1 shrink ratio in a compact 1.5 mm pre-shrink diameter, recovering to 0.5 mm for tight, reliable insulation on small-gauge wires and splices. Unlike generic tubing, it is supplied as a set of 10 transparent pieces, making it easy to see the connection underneath while providing a clean, professional finish.

Highlights

• 3:1 shrink ratio for secure coverage over irregular shapes
• Transparent polyolefin allows visual inspection of the joint
• Pre-shrink diameter 1.5 mm, recovers to 0.5 mm

In daily use

Slide a piece over the connection, apply heat above +90 °C, and the tubing shrinks to a snug, protective sleeve. The transparent wall lets you confirm the joint is properly seated before and after shrinking, reducing rework. Its flexibility and resistance to common chemicals make it suitable for automotive, marine, and general electrical work.
