Cellpack Heat Shrink Tubing 3-1, 15 m, Black

Cellpack Heat Shrink Tubing 3-1 – 15 m in Practical Dispenser Box

The Cellpack heat shrink tubing 3-1 is a versatile sheath made of cross-linked polyolefin, used for insulating and protecting cable connections. It comes in a handy dispenser box and is ready to use.

• The 3:1 shrink ratio allows adaptation to various cable diameters – from thin wires to thicker conductors.
• With a length of 15 meters and an inner diameter of 3 mm, many connections can be shrunk in one operation.
• The black polyolefin material is flame-retardant and reliably protects against moisture, corrosion, and mechanical stress.
• The dispenser box keeps the tubing neatly coiled and always at hand – ideal for workshop and mobile use.

What sets the heat shrink tubing 3-1 apart

Unlike standard heat shrink tubing, the 3:1 version offers a significantly wider adjustment range. It is especially suitable for applications where a cable with a connector needs to be insulated, as the tubing can be slipped over the connector. The UV-stabilized polyolefin ensures a long service life even in outdoor installations.

Ideal for electrical work, modeling, and automotive

This heat shrink tubing is valued by electricians, modelers, and in automotive technology. It is used to insulate solder joints, bundle cable strands, and protect feed-throughs from chafing.

How to use the heat shrink tubing

1. Cut a piece of tubing about 50% longer than the area to be insulated.
2. Slide the tubing over the cable end.
3. Heat evenly with a heat gun (approx. 150 °C) – the tubing shrinks to half its diameter.
4. Allow to cool – the connection is firm and sealed.
