Adjust flame distance based on flame size; if temperature is insufficient, lower the flame gradually.

Higher temperature results in faster shrinking; shrink speed depends on temperature and tubing wall thickness.

Do not apply flame directly to tubing; closer flame causes blackening.

Heat gun is preferred for even heating and best results without blackening.

Maintain proper flame distance to avoid damage.

Use heat gun when possible for uniform heating and optimal performance.
