6:1 shrink ratio tubing

MrCarbon 6:1 dual-wall heat-shrink tubing comes in four black pieces, each 26 mm long. The polyolefin tube has an inner diameter of 14 mm before shrinking and reduces to 2.3 mm after full recovery. An inner adhesive layer melts at 70 °C to create a waterproof seal. Operating range spans –45 °C to 125 °C.

Repairing frayed charger cables

The tubing suits anyone fixing cracked MacBook, USB-C, Lightning or HDMI leads where a tight, glue-lined seal is needed. It is not for buyers who want longer lengths for bundling multiple wires or a clear sleeve to inspect the joint. The 0.3 mm pre-shrink wall keeps the repair slim.

Adhesive liner creates waterproof bond

When heated with a lighter or heat gun, the internal glue flows and locks out moisture while adding strain relief. The thin 0.3 mm wall means the finished cover adds barely any bulk. Flame-retardant polyolefin meets safety needs without extra coatings.

Questions about this item

What cable diameter do I need so the 26 mm tubing shrinks down to a tight seal?

The tubing shrinks from 14 mm to 2.3 mm, so any cable between those diameters will be sealed.

Will the adhesive hold on the charger cables I already use?

Yes, the inner glue layer bonds to USB-C, Lightning, HDMI and headphone cables when heated.

How can I confirm the tubing has fully shrunk after heating?

The tube reaches its final 2.3 mm diameter and the adhesive flows out, creating a waterproof seal at 105 °C.
