About Heat Shrink Tubing — 2:1 Polyolefin

Polyolefin heat shrink tubing is the most widely used heat shrink material in electrical, automotive, marine, and industrial wiring — it is flexible, flame retardant, and resistant to moisture, oils, and a wide range of chemicals. The 2:1 shrink ratio means the tube shrinks to approximately half its supplied diameter when heated — a 7.5mm supplied I.D. tube recovers to approximately 3.5mm minimum recovered I.D., creating a tight, conforming sleeve over the cable or termination.

Heat shrink is applied using a heat gun set to the correct temperature — applying even heat along the tube causes it to shrink uniformly around the cable or component underneath. The low longitudinal shrink (less than 5%) means the tube retains close to its original 1 metre length after recovery. The HSTL7 range suits cables, conductors, terminals, connector barrels, and wire bundles up to approximately 7mm OD — suited to heavier gauge automotive and marine wiring, multicore cables, cable gland entries, lug and crimp protection, and conduit entry sealing.

Multiple colours are available to allow colour coding by circuit, polarity, phase, or system — consistent with standard wiring colour conventions. All colours carry the same polyolefin specification, 2:1 shrink ratio, and 600V rating.

Q: What cable OD does the HSTL7 suit?
A: The HSTL7 has a supplied I.D. of 7.5mm and suits cables and conductors up to approximately 7mm OD. With a 2:1 shrink ratio, the recovered I.D. is approximately 3.5mm minimum.

Q: What temperature is required to shrink the HSTL7?
A: The HSTL7 begins to shrink at 70°C and is fully recovered at 125°C. A standard heat gun is suitable.

Q: What colours are available in the 7mm size?
A: Black, Red, White, Blue, Green/Yellow, Clear, and Yellow. Select the required colour using the variant selector below.

Q: What is the voltage rating of the HSTL7?
A: The HSTL7 is rated at 600V continuous.

Q: How long is each piece?
A: Each piece is 1 metre in length.
