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 22.0mm supplied I.D. tube recovers to approximately 10.0mm 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 HSTL20 range suits cables, conductors, terminals, connector barrels, and wire bundles up to approximately 20mm OD — suited to large multicore cables, heavy battery and welding cables, large cable gland entries, lug and crimp protection on high-current connections, and conduit entry sealing in automotive, marine, solar, and industrial electrical installations.

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 HSTL20 suit?
A: The HSTL20 has a supplied I.D. of 22.0mm and suits cables and conductors up to approximately 20mm OD. With a 2:1 shrink ratio, the recovered I.D. is approximately 10.0mm minimum.

Q: What temperature is required to shrink the HSTL20?
A: The HSTL20 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 20mm 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 HSTL20?
A: The HSTL20 is rated at 600V continuous.

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