Frequently Asked Questions

Q: What widths does this automotive flannel harness tape come in?

A: This flame retardant flannel wiring tape is available in four widths — 9mm, 15mm, 19mm, and 25mm — so you can match the right size to any cable bundle or wiring loom, from single wires to large multi-cable harnesses.

Q: Is this tape safe to use near hot engine components?

A: Yes. The flannel tape is rated for long-term temperature resistance of up to 105°C, making it suitable for use in engine bays and other areas exposed to elevated heat. Its flame retardant properties add an extra layer of safety for automotive applications.

Q: Will this tape actually reduce rattling and squeaking sounds in my car?

A: Absolutely. The soft flannel material acts as a cushioned wrap around your cables, absorbing vibrations between wires and surrounding surfaces. This significantly reduces the minor squeaks and rattles that loose or unprotected wiring can create inside a vehicle cabin or engine bay.

Q: Does the tape leave residue when removed?

A: This flannel harness tape is designed with a clean-removal adhesive commonly used in professional automotive applications. When applied to wiring (rather than painted surfaces), it is intended to stay in place during vehicle operation and minimise residue upon removal.
