TE Connectivity Heat Shrink Tubing, Black 12.7mm Sleeve Dia. x 1.2m Length 2:1 Ratio, CGPT Series

Flexible, irradiated polyolefin tubing that is self-extinguishing as per UL 224 (excluding transparent tubing) and with a shrink ratio of 2:1 or 3:1. The tubing is resistant to most common solvents and chemicals. This heat-shrink tubing meets the most demanding resistance requirements normally encountered in an industrial context. There are many applications for the heat-shrink including strain relief, electrical insulation, and identification of cables and wires.

• Flexible polyolefin tubing
• Flame retardant (colours only)
• Extremely durable
• 2:1 and 3:1 shrink ratio meaning when heated the tubing shrinks to either half or a third of its original diameter
• Good resistance to chemicals and solvents
• Excellent physical and electrical performance
• Colour coded cables for easy identification
• Operating temperature -40°C to 135°C
• Heat shrink temperature: 80°C

What does a heat shrink ratio of 2:1 mean?
A ratio of 2:1 means when the tube is heated it shrinks to half of its original diameter.
What does a heat shrink ratio of 3:1 mean?
A ratio of 3:1 means when the tube is heated it shrinks to one third of its original diameter.
How can I shrink the tubing?
A heat gun or a heat shrink oven are ideal ways to shrink your tubing. Before heating always check to ensure you know the correct heating temperature of your tubing.

Remember to ensure all health and safety precautions have been taken prior to using a heating devise.
