WKK Heat Shrink Tubing Assortment, 465 Pieces in 9 Sizes, Thin-Wall Polyolefin 2:1, Black, -55 to +125 °C

The WKK 28113101 is an assortment of 465 pre-cut black heat shrink tubes in nine diameters, made of thin-wall flexible crosslinked polyolefin with a 2:1 shrink ratio — for technicians and installers who insulate solder joints, splices and connector ends and want the right size at hand.

Shrinking starts at +70 °C and full recovery is reached from +100 °C. Once shrunk, the tubing works from -55 to +125 °C and is UL224 and CSA approved, VW-1 flame rated and self-extinguishing.

• 5 × Ø 19.0 → 9.5 mm, 70 mm
• 5 × Ø 25.4 → 12.7 mm, 70 mm

• Insulate solder joints and crimp splices on low-voltage wiring, fan leads, LED strips and sensor cables.
• Add strain relief and a neat finish where a cable enters a connector.
• Choose a tube that slides over the widest point and shrinks to at most the smallest diameter you need to grip.
• The tubing is printable, so it can also be used for marking.

• It will not seal against water — there is no adhesive inside.
• It will not grip anything thinner than its recovered diameter (1.2 mm for the smallest size).
• It is not halogen-free.
• It will not shrink without heat — a lighter scorches; use a heat gun.
