Shrink tubing for businesses
Consultation, quotation, and fast delivery

For a quick quote, please send the following.

To help us recommend the right heat shrink tubing and provide an accurate price quickly, please send:

• Outer diameter of the object (Ø mm) / size before shrinking

• Shrink ratio (2:1 / 3:1 / 4:1 / 6:1 – if known)

• With adhesive (dual wall) or without adhesive

• Length (per piece or per meter) and quantity (pcs/m)

• Environment: indoor/outdoor, moisture, UV, oil/chemicals, temperature

• Color and any requirements/standards (e.g. UL/CSA, RoHS, etc.)

Tip: Don’t have all the measurements? Send us a photo with a ruler or something similar for reference, and we’ll help you determine the right size.

How does shrink tubing work?

Because KACAB’s heat shrink tubing is available in a wide variety of materials that are developed to operate in temperatures between -75°C and +260°C in constant working temperature. The tubing can be thin-, medium- or thick-walled and are delivered with or without a glued inside. All standard heat shrink tubes are therefore flame retardant and or self-extinguishing. They have a shrinkage capacity from 2: 1 and up to 6: 1 and can be delivered in a variety of colors and sizes (0.6 mm – 1500 mm). Our tubing vary, for example, from economic, to high-tech, and are approved according to UL224/CSA and specified with a variety of MIL standards. Product quality is our key word. All our products also meet or certainly exceed all approvals/environmental requirements such as RoHS, and where applicable, UL, Mil, ASTM, VDE and Cenelec HD623 (for “LV joints kits”).

What is Heat Shrink Tubing?

Heat shrink tubing is thus a special type of plastic tube whose diameter shrinks when heated. The shrink tube is also used to insulate wires and protect them from abrasion. The application of heat is done at the same time with a hot air gun that you can buy from us. There is shrink tubing with or without glue, where the glue not only attaches to cable sheaths and conductors but also seals extra. Heat shrinkable hoses are comparatively divided into shrink ratio, hence that is how much the hose’s diameter can maximally shrink when heat is applied. The most common ratios are between 2:1 to 6:1. furthermore, the greater the shrink ratio a heat shrink tube has, the larger the uneven application it can be shaped around. The wall thickness and diameter change especially when shrinking a heat shrink tube.

Frequently Asked Questions About Heat Shrink Tubing (FAQ)

Which size should I choose?

Start with the object’s outer diameter: the tubing should slide on easily before shrinking and fit tightly after shrinking. Email us the diameter in mm and the application, and we will recommend the right size.

2:1 or 3:1 (or 4:1/6:1) – which should I choose?

2:1 is often sufficient for straight, uniform dimensions. 3:1 to 6:1 offers a wider shrink range and is better suited for connectors, uneven transitions, or varying diameters.

When should I choose adhesive-lined heat shrink tubing?

Choose adhesive-lined heat shrink tubing (dual wall) when you need extra sealing and moisture protection, better mechanical retention, or when the application is more demanding, such as outdoor, marine, or vibration-prone environments.

Can heat shrink tubing withstand cold, heat, and harsh environments?

We offer materials for different environments and operating temperatures (for example, from approximately -75°C to +260°C depending on the type). Tell us about the environment and your requirements, and we will select a suitable material and wall thickness.

Do you offer different wall thicknesses and colors?

Yes, heat shrink tubing is available in thin-, medium-, and thick-wall versions, as well as in a range of colors and sizes. We help you choose the right type for insulation, protection, or sealing
