Ratio 3:1
The shrink ratio is the relationship between the inner diameter before shrinking and the smallest possible inner diameter after shrinking.
3 to 1 shrink ratio means that the tubing's inner diameter can shrink down to 1/3 its original inner diameter. Thus, the tubing is three times larger supplied than compared to when it has been shrunk down.
For example, 1-1/4"(31.75mm) of the pipe diameter becomes 5/12"(10.58mm) after heat shrinking.You only need to heat it evenly with a hot air blower to make it shrink.Initial shrinkage temperature:90℃(194℉),fully shrink temperature:125℃(257℉)，range temperature:-45℃-125℃(-49-257℉).Dielectric strength:rated up to 1000V.
