The ID of maximum continuous length is φ25, and Φ25 or more is 1 meter/pcs.
Prepare surface: Clean the conductor or component surface to remove contaminants before heat shrinking.
Select size: Choose the correct tubing size based on the conductor or part diameter.
Apply heat: Use a heat gun or controlled heating source to evenly shrink the tubing over the target area within the shrink temperature range (90°C ~ 170°C).
Ensure full coverage: Confirm that the tubing has fully recovered and snugly encapsulates the protected area for reliable insulation.
Cooling: Allow to cool naturally before mechanical or electrical service.
