Frequently Asked Questions
Q: What heat source can I use to shrink the tubing?
A: You can use a heat gun, which is the most recommended method for even shrinkage. A lighter or match can also work for small pieces, but a heat gun gives the most controlled and professional result. Avoid using an open flame directly on the tubing for extended periods.
Q: What sizes are included in the heat shrink tubing kit?
A: The kit includes an assortment of multiple diameter sizes suitable for a wide range of wire gauges and cable thicknesses. Both colour and black options are available, with bag sets ranging from 127 to 560 pieces and box sets up to 800 pieces depending on the variant selected.
Q: Is this heat shrink tubing waterproof or moisture-resistant?
A: The crosslinked polyethylene construction provides excellent moisture resistance, making the tubing suitable for use in automotive, marine, and outdoor electrical applications. For fully waterproof sealing, consider using adhesive-lined heat shrink tubing variants.
Q: Can this tubing be used in high-temperature environments?
A: Yes. This heat shrink tubing has an operating temperature range of -55°C to +125°C, making it suitable for use near engines, appliances, and other warm environments where standard insulation tape may not hold up reliably.
