This is suitable for polarity marking and circuit identification. For a junction that must remain watertight — crimped ferrule exposed, wet bulkhead penetration — use adhesive-lined tubing: the adhesive version exists in the same diameter.\u003c\/p\u003e\n\n\u003ch3\u003ePolarity marking\u003c\/h3\u003e\n\u003cp\u003eRed marks the positive on a DC installation. The color code only has value if applied consistently throughout the installation: a red sleeve on a negative is worse than no sleeve at all.\u003c\/p\u003e\n\n\u003ch3\u003eChoosing the correct diameter\u003c\/h3\u003e\n\u003cp\u003eThe 3 mm diameter must fit over the largest point to be covered, and the 1 mm diameter after shrinking must be smaller than the support so the tubing grips.
