    The tubing is made of polyolefin, which is a durable and reliable material for electrical insulation.

  2. What color does the heat shrink tubing come in?

    It comes in black, which provides excellent UV resistance and durability to protect your wires or cables.

  3. How big is each piece of tubing?

    Each piece of 3M™ SFTW-203 Heat Shrink Tubing measures 1.22 meters long, with an outer diameter of 12mm and inner diameter of 4mm.

  4. Is it easy to install this heat shrink tubing on my wires or cable bundle?

    Yes! This type of heat-shrinkable tube shrinks easily once exposed to high temperatures like from a heat gun. This makes it perfect for insulating connections quickly between secure ties or twisted wire bundles

  5. How many pieces do I get when I order this product?

    You will receive one length (or "piece") measuring at exactly 1.22 m so you can cut off various lengths as needed depending on how much cabling coverage you need.

Product Description: 3M™ Tubing Heat Shrink Tubing SFTW-203

The 3M™ Tubing Heat Shrink Tubing SFTW-203 is an excellent choice for shrink fit jacketing and insulation of flexible wire bundles and temperature sensitive components. Its extra flexibility and low shrink temperature make it ideal for these applications.

The SFTW-203 tubing has a 3:1 shrink ratio, making it the perfect insulation for end terminations where the connector body is larger than the cable. It is also great for repair applications where the tubing must be slid over a connector. Additionally, the SFTW-203 tubing can be used to insulate an oversized component in line with the wiring.
