Product Details

ATUM - Moisture Proof Sleeving 3:1 or 4:1

The ATUM range of heat shrink tubing has been specifically designed to provide environmental sealing and protection in a wide variety of electrical applications and is suitable for both commercial and military use. The tubing has an internal adhesive lining that when heated forms a moisture proof seal that bonds to a wide variety of materials. The high expansion ratio makes it possible to repair most damaged cables without the need to remove any connectors.

Features and Benefits

• Provides excellent environmental sealing for electrical components, wire splices, cable jackets and harness breakouts
• High strength bonding – the adhesive in ATUM tubing bonds to a wide variety of plastics, rubbers and metals
• Medium walled for increased mechanical protection
• Flame retardant jacket
• Polyolefin material – commonly used insulating material, flexible and durable
• Heat shrink ratio of 3:1 or 4:1 meaning when heated the tubing shrinks to either one third or one quarter of its original diameter
• Standard black in colour
• Operating temperature range of -55 to +110 °C
• Minimum shrink temperature: +80 °C
• Supplied in lengths of 1.2m

What does a heat shrink ratio of 3:1 or 4:1 mean?
A ratio of 3:1 means when the tube is heated it shrinks to one third of its original diameter. The original tubing size is three times larger than its shrunken form.
A ratio of 4:1 means when the tube is heated it shrinks to one quarter of its original diameter. The original tubing size is four times larger than its shrunken form.

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.
